I like how you posted directly to the fractal wood burning part which is the most insane thing I've seen people try and DIY. Incredibly dangerous.


ive seen clips and images of them over the years and i thought about doing it myself, but i had no idea yoy needed a fuckin backwoods transformer setup until just now lol fuck that..


Yeah I thought they just used a car battery. I didn't know you had to step-up the mains supply. That is ridiculously dangerous.


You couldn't just use a car battery, you'd also need an inverter to generate AC. Plugging a battery directly into a transformer just makes it an expensive space heater.


Right? The only thing I got out of this video was dumbfucks don't know microwave transformers are deadly... And everyone should cause the back of your microwave is plastered with warnings not to fuck with it. There has to be an actual machine designed to do this kinda thing that's not a death trap.


Even a properly designed machine would be fucking dangerous. By design, it needs to deliver a ton of energy into the wood to achieve this. I think you'd need something with an enclosure and safety mechanism where it won't turn on unless closed. Have leads that are mostly covered that you place on the wood, seal it up, and hit a button. Even with that though I could see people bypassing the safety switch so they could do things like moving the contact point.


Yup. I'm a biologist and do gel electrophoresis and that's exactly how the boxes are designed for 100-300V. The electrodes are built into the lid so you can't touch the electrified buffer while it's running. If the lid comes off, the circuit is broken. The power supply has circuitry to check for things like shorts and won't provide power if anything seems wrong. https://www.labdepotinc.com/p-61341-mini-gel-electophoresis-systems?gclid=EAIaIQobChMIkqOaley--AIVdhbUAR2_zg5BEAQYAiABEgInY_D_BwE It probably wouldn't be too challenging for a few engineers to design an industrial process to make this artwork safely but it needs containment and purpose-built equipment, not someone screwing around in their garage.


I could see this. Make a 4'x4' open-top (ventilation is probably pretty important for this to work safely) enclosure with a heavily insulated base and heavily insulated walls (glass?) Have the leads attached to insulated poles that go through the enclosure walls so that they can be manipulated without getting close to the metal clips. Rig up a button and foot-operated switch. Your foot must be on the switch to start the machine using the button, and it turns off if your foot leaves the switch. I'm not an electrical engineer, so I'm not sure if all of this would still make it 100% safe, but it'd definitely be better than holding some alligator clips with your hands running 2000v through your kitchen table.


Microwave transformers are just a thing you shouldn't fuck with. People with electrical engineering degrees are the only people qualified to fuck with microwave transformers, and they don't because you don't fuck with microwave transformers. They arc and kill you way too easily.


I think she said in the video that 2 of the 34 confirmed deaths to this wood fractal burning were electricians. Any mistake or complacency with high voltage and you're gone.


You'd think the guys who work with angry pixies, know not to fuck around with angry pixies.


“I’ll try to change this outlet before you find the fuse box. Go.”




Linus wouldn't do anything that dangerous. The worst I've seen him do was that 3500watt power supply he was poking around with. Also with giant warnings on screen saying never do this


That was funny they were way too concerned about their connection to the 240V mains. They had wire nuts and wrapped it in electrical tape which is basically code, out in the open it's perfectly good for a temporary hookup but could become damaged over time. The biggest risk was caps, which can be discharged and I believe they did, and a possible fire, but I assume they have a dry extinguisher at the ready.


You're looking for Mehdi: r/ElectroBOOM


Late to the thread, but figured I'd post anyways. I work in a lab, mostly in a clean room. They're the kinds of labs where you wear the full hooded suit (called a bunny suit) to protect both the lab and you. There are *a lot* of safety trainings to go through just to get in, and more training for every piece of equipment you want to use. I'm not exaggerating when I say safety regulations are written in blood. People you would assume are pretty intelligent and highly trained have provided countless hours of accidents for safety videos. And labs all have their own horror stories during training; I've never seen the same safety disasters twice. People get complacent, confident, tired, negligent, and make mistakes that can come with the ultimate consequence. *Never* relax when you are working with hazardous materials. They deserve our constant vigilance.


+1. WHMIS is important and specialized training saves lives. Used to work in Aerospace. High Voltage and Heavy things are no joke.


The true nature of magic smoke is still unclear and its interactions with the human body remain a mystery to modern science. It's best to leave the magic smoke inside the machines where it belongs.


At 2000v things you don't expect to conduct with start conducting, so you need to make sure that whatever you're using to insulate you is actually adequate for the task. If these are just regular house electricians, they likely haven't worked with or even studied these voltages all that much.


Had to stop a guy once, he legit though that cut resistant gloves would protect him while he was working on a 277v circuit. 277v will really hurt you, 2000v will fuck you up.


It’s this. Electricians are used to being pretty relaxed about safety because the voltage tickles a bit. Edit: Here in the US atleast. I've seen Electricians do LIVE rewiring stuff. And it just boggles me.


I was an electrician in the Navy for too long. When I think about the dumb shit we would do I cant believe I am alive. I had my moment of clarity at the top of an escape trunk out of the lower level of the engine room. I was at the top of the ladder about 50 ft up investigating a light bulb. I pulled the cover and noticed the ballast cover was missing and the ballast looked like it had something all over it. I touched it, it was energized and it was all I could do to hang on to the metal ladder as I was being shocked and try to jerk my hand away which had clamped down on the ballast. All I could think was "oh, so this is how it happens". Started being way more serious about safety after that. That was only 120V and I worked with up to 4KV. Now I work near much higher voltages and I stay the fuck away.


Best to have a learning moment when it’s survivable.


You never forget the times you almost died It's the cruel mistress of survival instinct


Not in the UK. 240V Household. 415V for 3 phase industrial. 48v in a phone line, do NOT strip the insulation with your teeth. Don't ask how I know, and don't ask how my filling literally exploded. :-/


US/Canada household is also 240V line to line. They get 120V from the 'split phase' going line to neutral. Big appliances like dryers and cook stoves are 240V, lighting and small appliance receptacles are 120V. Low voltage industrial electrical in Canada is three phase 347/600V usually. In the US it's 277/480V. My big learning moment was having a 600V motor starter explode in my hand. I had the cover off, and missed that the pump motor I had replaced wasn't in fact defective, but the cable connecting it to the starter had been damaged by a frost heave and was now a dead short. I saw spots for a long while after and have a bunch of tiny scars on my hand still. We used to make Jacob's Ladders from old oil furnace igniter transformers. I think they were 10kV on the output end.


I know an electrician who believes perpetual energy machines exist and that the government is covering it up. It's possible to have skills in a relevant trade and still be as thick as pig shit.


Electricians are not electrical engineers. They're *very* different levels of education.


I have a PhD in electrical engineering, but my parents think I’m essentially an electrician.


And let’s just go a step farther, we’ve got this incessant need to label everything. So people are either smart or dumb when most people do smart AND dumb things. Plus certain members of the population haven’t grown beyond labels. So to them a good person can’t do bad things except for a good reason. So they assume smart people are always smart. Even electrical engineers can have blind spots in their technical knowledge. We live in a world of grey filled with people that only see black and white.


I work with a guy, great electrician. He asks me the other day, why don't we put a dynamo on a Tesla so it could recharge while you drive. Facepalm.


Correct me if I'm wrong, but that's what a hybrid does, right? When slowing down the rotational force is used to recharge the battery?


Yes, that's called regenerative braking, you're recovering momentum of an already moving car. It doesn't break the law of conservation of energy though.


And to add, it's something all electrical (so also hybrids) cars do because the type of motor used can be turned into a generator for (nearly) free.


I did some high voltage tinkering for a high school project, trying to build a plasma speaker, and I went down the HV experiment rabbit hole for a while. On the various forums you'd see experienced hobbyists with a bunch of high voltage projects under their belt and a very common sentiment was that they weren't willing to fuck with microwave transformers because they are just that deadly. If you use things like 20kV flyback transformers from old CRTs or tesla coils, the secondary windings are so thin that you can't have the massive amounts of power that MOTs produce and because they typically are used in higher frequency circuits which makes the current flow close to the body surface due to skin effect. It might still stop your heart (especially if you touch it with both hands), but it won't grill your insides if you fuck up.


When something is so dangerous even Electroboom doesn't fuck with it.


I'm just wondering what size of FULL BRIDGE RECTIFIER it would take to convert 1000w microwave to DC power...


On the output side? Smaller than you might think. Diodes drop about a volt, so when they're rectifying high voltage (and this low amperage) they can be really efficient). Won't be all that big, just kind of long so energy doesn't just arc across the diode.


He actually did make a video about this kind of wood art, but it (possibly rightfully) got ~~banned~~ removed from YouTube. Obviously, don't try it, but here's a re-upload of it. [https://www.youtube.com/watch?v=8qwp0Oq\_dzU](https://www.youtube.com/watch?v=8qwp0Oq_dzU)


Guy is next level. The fact that he's survived so long doing what he's doing is a testament to what an expert he is.


My favourite was when he blew the breakers on an entire UK hotel. You can't go showing a guy like him the electrical safety features we have over here, he'll just see it as a challenge lol


I got an electrical engineering degree to assuredly say that I don't want none of that smoke. I always say "never mess with electricity."


I got an electrical engineering degree so that I know **why** I shouldn't touch microwave transformers.


That's a big one. There are ways to make this safe enough to do, and PPE that is effective, but you have to understand what you're protecting yourself against and why. It's not something even an electrician is going to generally have the knowledge to be able to set up themselves without consulting an expert. And if you're attaching alligator clips to a microwave transformer, you're already doing things wrong.


My colleges computer science has two classes that we went and took over in EE: Microcontrollers (8-bit assembly) and Digital Logic. In one of the labs there was a chart showing deadly voltage ranges. It was a pretty scary chart and it really stuck with me. I don’t mess with electricity ever.


And StyroPyro, never forget StyroPyro when it comes to microwave transformers.


Another YouTuber named Big Clive goes into detail about the dangers of people doing this: https://youtu.be/FBeSKL9zVro


A coworker of mine recently did this with their 6 year old son. I knew it was dangerous, but didn't realize the extent of it. Glad nobody was hurt in this case.


I hope you send them this video!


Link this to them now. They did it once, they'll do it again. PLease.


In some alternative timeline, I’m probably dead cause that wood fractal thing is something I would have done Saw that video and thought it was cool. Just never got into it


Here's me seeing the jumper leads thinking they are doing this with a car battery. Nope, pulling apart a microwave and using the transformer to give them 2000V. This is just insane.


Just use a soldering iron and draw burn markings on the wood. Much safer and you can be creative.


It wouldn't look even remotely the same if you try to do it freehand. Source: painter


Nah, its okay. Thanks for teaching me about it. Not interested in it anymore


[Interest in fractal wood burning after watching the video](https://c.tenor.com/kKIEUhvP2gAAAAAC/seinfeld-no-thanks.gif)


This is one of those things that really makes me think basic electric principles should be required learning for secondary school. I've just got a very basic understanding of it, but even with that when I looked into trying this stuff myself I saw "microwave transformer" and just noped all the way out. There are just too many devices around the home these days with lethal amounts of power going through them.


There's really not a lot of lethal electrical devices around the house. The microwave definitely is though.


Microwave is the most dangerous according to bigclive. I think some respect is also required with TVs and some other things that have large capacitors. They can end up holding a deadly charge. So someone might think they are safe to unplug and open up. Then you accidentally bridge the contacts on the capacitor and get a nasty shock. I assume that means a lot of things like dishwasher, laundry machines, etc have big motors but don't pose that much of a danger unless you get hit by them while they are moving. And some devices are low-voltage and high amps. Amps can be really deadly, but when the voltage is low enough the current won't want to flow through us because skin has decent resistance. I mean, I'm not going to open any of them up to find out. I don't trust myself around electricity.


The old CRT tvs had some 30,000 volts if I remember right, and could discharge even unplugged. The new ones aren't so bad but still ain't a good idea to fuck with.


Can't most capacitors discharge even when unplugged?


Yes, in fact that is their primary purpose to an extent. You can think of them as a temporary battery (the mechanism behind how they work is different, but they function that way.) They are why, in a lot of older devices, like CRT TVs, the picture doesn't immediately shut off when you unplug it, but rather does a little fizzle off routine. That's a capacitor discharging.


This should be a necessary PSA for kids https://imgur.com/gallery/p46ytk1


"Not only will this kill you, but it will hurt the whole time you are dying"


When I was a kid in the UK I had the shit scared out of me by a PSA we had to watch in school where a kid sticks a fork in a toaster, *literally fucking dies,* then a cloaked figure shows him all the people miserable about him dying before revealing that *ah-HA!* the cloaked figure was the dead boy all along. It's my PSA white whale because nobody believes me when I say we were shown, at 8 years old, a trouser-soiling horror movie *specifically* about the dangers of sticking a fork in a toaster, but bugger me if I can find a copy of the damn thing anywhere.


>*This is one of those things that really makes me think basic electric principles should be required learning for secondary school.* This was part of my physics curriculum in high school, but I’m not sure how much it would help. For me, it was a lot of math… I didn’t remember any of it after about a year. That said, I certainly know enough not to play around with microwave transformers! Also, many electronics use capacitors to store charge, so I’d be scared to play with microwaves and jumper cables even if they were unplugged.


The dangers of a lot of household items can be taught with physics that I think is intuitive and easy to remember. Anything with high quantities of potential energy is potentially highly dangerous. Big springs, big currents, big voltages or things falling from high up? Think a bit about safety and if you can do whatever it is safely.


Right? Like, do you know where a microwave transformer belongs? In a fucking microwave!


I forget who it was, maybe bigclive? showed off a "safeish" design for one of these things. It used a momentary button spaced far apart enough that you needed both hands, I think one for each hot/neutral going to the transformer. The idea being that so long as you weren't incredibly stupid and like having the whole thing in a puddle of water or something, it would be impossible to run the device while touching a live wire or something with either hand since both had to be "busy" to run it.


Two momentary buttons wired in series. So that both need to be fully depressed for it to energize. As much as that design helps, I'm not sure what happens if you had paralysis from a shock. Do you just continue holding the buttons? I'm not an electrical engineer, but I'm pretty sure the design he sketched could be made safer still.


Reminds me of that time crazyrussianhacker made a video about basically using a block of dry ice and a fan as an air conditioner. Another YouTuber had to make a video that subliming a few kilos of CO2 into a confined space is a really terrible idea, if not lethal.


i get all my cooling advice from this dude called ***crazy russian hacker***


I remember a news story where people died because of that. An instagrammer dumped a ton of dry ice into her pool for her birthday to make it look cool and three people died, including her husband.


They thought the pool was too hot, so they threw in 25kg of Dry ice.


Yikes. Pure CO2 is denser than air so it likely displaced the air in the area between the surface of the water and the top of the pool. Anyone popping their head above the water for a breath would have passed out. Once CO2 levels hit around 10% you're a gonner


The pool is a very effective way to make a death trap: * The water ensures the CO2 sublimates quickly * It's a convenient pit to contain the CO2 * The fancy smoking pit tempts people to jump in, exposing them suddenly before they can notice and GTFO, and they'll be excited (needing a lot of air and taking a deep breath as soon as they come up) * If the CO2 doesn't finish the job, the drowning will


I love her. Great vids on 'fixing' bad cake jobs and calling out BS from several content creators.


And her science is on point! Like..it has become profitable for a lot of people to debunk actual science and promote "science". But they are debunking nonsense. She is doing actual tests, in real conditions and explaining exactly the limits of her setup and what it can convey. Ann Reardon is a good scientist and that is awesome.


Well she is a food scientist.


The combination of soothing voice and Australian accent makes my ears go blissful-face-surrounded-by-hearts-emoji.


Then her husband Dave randomly shows up to try what she makes and he seems like a good hangout too


Doing a good thing on YT? Surprised her channel hasn't been unfairly taken down already.


She also has a book on Amazon. I love her so much . She is super cool


Her husband is awesome too. He’s always the taste tester


His reactions to some pretty terrible items she has had him try are amazing. They seem like genuinely nice and good people. It really upsets me that YouTube's algorithm basically shuns creators like her. Instead YouTube pushes dangerous in this case or otherwise useless and fake videos because they are brief and fit the "user engagement" part of their algorithm because they get play through because they are just shotgunned up.


I’m subscribed to her and I haven’t seen her videos on my feed for a long time. That makes more sense. What a crappy thing they did!


That's why she's moved into this kind of content. She used to have a purely baking channel but was being left out in the cold in favour of shitty overproduced food hacks that most of the time don't work at all. She started with debunking them and now has transitioned into general shitty hack debunking and calling out YouTube while also keeping in some of the baking/cooking.


I have made her chocolate cake from that book. Seriously the best chocolate cake I have ever eaten.


I did the rainbow/refracting chocolate for my boyfriend for Christmas, and it turned out so cool!! All you need is a $5 refracting sheet and some melted chocolate.


I thought it was a rainbow FRACTAL chocolate cake for a second and I was like DON’T DO IT!


Especially when she reveals how YT itself monetizes the user's videos on other platforms like Facebook... while the YT video has less that 34k views, they promote it on FB having over 3M and their TOS states the creator has no right to any profit or right over the video. YT is another Google Scam.


Yup. She actually touched on it in the beginning of this video


The Wisconsin incident she references is local to me. Initially they called it suspicious and felt it was homicide. Took awhile to get to the bottom of it that they were just doing this electrified wood. There are even entire shops now doing this... And frankly it is a design concept that gets boring pretty fast, to me they all look the same and are a 'meh' just like [woodburned flags](https://www.google.com/search?q=wood+burned+flag) that became a fad everyone made to try and sell.


Why not both, from lower down your link lol. https://www.tractorsupply.com/tsc/product/tx-usa-corporation-wood-burning-flag-wall-decor-ntl-m21748


Wow that’s ugly


I saw your comment and it somehow was even uglier than I expected.


I saw yours, and it's *still even uglier* than expected


I'm just a bit in shock myself. Presumably they've made thousands of them and they should be semi unique, surely there had to be one that didn't look that awful


> Access denied Guess its AMERICANS ONLY


Did...did they forget to count the stripes? Jesus christ.


Perfect! Haha


"a design that gets boring fast" Like those toxic and poisonous Epoxy Turnings everyone seems to be doing? They look great, but considering many types of resin are highly toxic and carcinogenic, i dont see the plus in having kilos of resin waste, just so some tosser can make another video.




She is still mostly cooking channel. Since shes also a food scientist and uses those methods properly, they transfer over well to just about anything that looks too good to be true. But people click on the 'too good to be true' so bad actors keep making them


It's absolutely not the sort of thing I would usually watch on YouTube but her channel's great. She's a good communicator and knows her stuff about food (not just cooking, but the chemistry behind it). Love watching her videos and seeing Dave enjoy (or not) her recreations.


> Dave Did you see her video where she was debunking clickbait videos, but then he just shows up and basically says "my wife was going to make a cooking video, but accidentally discovered a Russian disinformation campaign, let me tell you about it"?


Wait what???? Where is the link?


https://youtu.be/pvqa8dsBtno Dave starts digging into the behind the scenes stuff at about 13:15 of the video.


Wait, Dave used to be a journalist? Damnnn, I admire that man so much.


I love their whole family. They seem like stable kind people?


Thanks murphymc


That made me want Dave to have his own channel, it was super interesting.


Same. While I love cooking I'm not really a baker but she makes good interesting videos. Even her baking videos are enjoyable.


> She is still mostly cooking channel. Like, what percentage is human vs cooking channel? 90/10?


She used to be. But she still is, too.


She also has a cookbook that I love because it really explains the science behind what you're baking. It has fun complex things but also it just has like scientifically most moist cake you can make.


Oh! I remember this lady! One of her videos blew up where she was trying to replicate some stupid fake ~~recipients~~ recipes that obviously were never going to work. I remember that video was a little bitter sweet since she also spoke about how these terrible soulless assembly line videos were making it really hard for actual smaller content creators to get noticed. Great to know her channel is going strong!


I remember that one too... I think it was with fake content creators on Cyprus or something peculiar like that. Opened my eyes to spot at least some of the BS out there!


> One of her videos blew up That was careless of her!


Craft and DIY youtuber channels are notorious for being oblivious to safety rules. I've never seen a resin video that mentions how dangerous the fumes/liquid form of it can be.


On a similar note, the chemistry channels are absolutely fucking insane to me. * Little to no PPE * Volatile materials handled near open flames, or even heated directly on a hotplate * Terrible ventilation * Extremely toxic chemicals handled negligently * Incompatible chemicals stored in close proximity I'm glad these guys are making chemistry look cool to a younger generation, but the lack of basic safety in their demonstrations is bonkers.


Check out NileRed for a chemistry channel that does *all* the PPE, ventillation, and protective magic circles if needed


Was that the guy who made hot sauce from nitrile gloves?


The very same, yes


Yeah, that guy has a real lab. Usually the camera is zoomed in on the experiment but sometimes he'll interact with other people in the lab and it is serious business.


The guy is incredibly good.


Nilered is good for actually having fume hoods and stuff. Thoisoi has his own glovebox setup. Explosions and fire is a real explosives chemist and all his YouTube projects are at teeny tiny pretty safe scales.


Or how hot it can get while curing. That shit can give you burns.


As someone who’s seen the TikToks and YouTube videos I had no clue it was hot or even dangerous.


As someone who’s only experience with resin is seeing a rotating hot dog encased in it every few months, I had no idea either.


I didn't know that it could even get hot until I watched the smarter every day video (I think) where he was trying to capture the prince Rupert's drop exploding in resin. They were very careful not to touch it, and you could see smoke coming off of it as it was curing.


If you pour too much of a not-thick pour resin, it'll get hot enough to boil.


When I dabbled in some costume making, the ones I looked all all emphasized you *needed* a good respirator with new/fresh biological filters "unless you feel like getting cancer in 15 years". Same with not fucking with fiberglass without a respirator & eyewear too.


I mean, there was one of these 5 min crafts videos that [taught how to make white strawberries by using bleach](https://youtu.be/ApO4c2AkLqw?t=455). This videos are aimed at children. Than there is [this abomination](https://youtu.be/CEQaYdvs478?t=438). Even if they are "oblivious" Youtube should step up and do something, but according to them these are not against their terms of service.


*angle grinding while wearing gloves but no shoes or eyewear intensifies*


I still can't believe Youtube got away with removing dislikes. Dislikes are necessary and essential for how-to videos and tutorials. Well, I guess I can believe it but I don't want to


"This how-to killed me. Would not recommend. 0/10" -a corpse


Facebook and most social media don't have them either. When we think of the rise of complete idiots like anti-vaxxers, while I can't call that wholly responsible, it's done its part in enabling it.


If anyone here is new to Ann Reardon, check out her channel. She's amazing. Her videos are educational, informative, and really entertaining. She speaks out for content creators, debunks a lot of misinformation, and just seems like a genuinely good person.


Watching her husband eat the cakes and stuff she makes from terrible TikToks is the kind of wholesome content I am here for.


And then there was one episode when he went full investigative journalism on a Russian content farm, and I was like "damn Dave, I thought you were just supposed to eat the cakes and be wholesome" 😄


People forget he was a journalist and news reporter. Man knows what he's doing! So awesome to see how they work together in both a comedic and informative way.


I think it's because he shows up dressed like he just got back from the X-games in the mid-nineties. Which I 100% relate to as I am also an old man who dresses like I did in High School in the mid-nineties.


That was the video that really sold her channel to me. Prior to that she was making neat content, but then I saw that and my ears perked up. Love these Aussies.


Dave is the real MVP.


He eats it so we don't have to.


Dave ate charcoal icecream for our sins


Oh god, I forgot about that one. That poor, beautiful man.


He really just goes for it too


She recently did an [AI-written cake recipe](https://www.youtube.com/watch?v=nUqPOsgu0uo) and it was a hilarious video, I cried laughing


"Pour the batter into the baking pan." *Plonk* I get the giggle fits everytime I think about it!


I love the jokes. "How do you make a cheesecake? One day at a time"


I got to say the cake walking into a bar one was a pretty good anti joke


That killed me. That was legitimately hilarious. Bit of a thinker.


Lost it at the sticks of gum


It is one of the funniest things I've seen in months. The AI splitting things in half and then combining them together.

I really love her ancient/Victorian Era recipe videos as well


Wow, I'd never had known the extreme voltage that is being used. Advisory notices would benefit the viewers of youtube videos on this subject. Also, can anyone ELI5 for *volts vs amps* in terms of stopping a heart, or death?


Volts vs Amps: Which kills you? _Both._ Think of electricity as a water pipe. Volts are the pressure, Amps are the volume. Our bodies are driven by electrical signals, and external shocks disrupt these. That's why a good static shock [5000+ volts, but _very_ low amperage] makes your hand tingle. That same static shock applied directly to your heart could kill you by making your heart all tingly as well. Let's say it's about the same as a Super Soaker. But it's a good thing we have a lot of damp meat around it so that doesn't happen. The transformer trades Amps for Volts [or vice versa] and beefs up the the voltage so high that it's possible that enough energy can find a way through all that meat to make your heart tingly. Like how getting hit with a firehose can still deliver enough energy to hurt or kill and unlucky person. If we want to be reductive, let's just say that the 2000V output on a microwave transformer is an unlucky mix of being high enough voltage while still delivering enough current to likely kill you even if you're not delivering that shock directly across your heart. Electricity _prefers_ the path of least resistance, but will still take _all available paths_.


Thank you for this. She kept saying 2000 volts is a lot and I was thinking "Wait, isn't a taser like 50,000?" Even a static shock is like 5k. Obviously there is some SERIOUS current going through that wood but it's not like 2k volts alone is deadly.


https://physics.stackexchange.com/a/244092 Carpet shocks: * 750V, 0.04mJ - Spark threshold, visible in darkness * 4KV, 1.2 mJoules - Winter doorknob spark, small snap, little pinprick * 7KV, 3.7 mJoules - Fairly nasty spark, louder snap. Ouch. * 35KV, 100 mJoules - Highest measured spark: northshore Alaska winter, vinyl truck seat. * Taser, tens/hundreds of mJoules, repeating pulse * 100KV, half a joule - VandeGraaff machine with chain of children connected


Imagine going to work on a cold winter morning and all of a sudden your ass gets rocked by the highest recorded static electric shock the world has ever known.


The fact it was recorded suggests that he didn't get zapped when recording it. It also suggests he got zapped to hell beforehand and was pissed off enough to figure out exactly how bad it was.


Yeah some Alaskan electrician got their ass absolutely *smoked* by static electricity and decided to get to the bottom of it.


[See my post below](https://www.reddit.com/r/videos/comments/vh253l/ann_reardon_debunks_the_deadliest_craft_hack/id5hj1c/) You can't really talk about current and voltage separately, as one is *directly* dependant on the other. > A = V/R >where A = Current, V = Voltage and R = Resistance Both a taser and a static shock will deliver an extremely high amount of current to your body. So why does a static discharge only sting, and a taser *usually* doesn't kill? Mostly, time. A static shock only has enough energy to keep that high current flowing for a microsecond or less. A taser is similarly designed to deliver short pulses of electricity and cannot maintain a high current for long. Plus, the electrodes stick to the skin and don't generate a path through the victim's heart. Meanwhile, the wood burning project will kill you because your home's electrical installation can keep up that current for long enough to hurt you. (keep in mind: I'm oversimplifying the taser part. The voltage on a taser drops after the initial arc, plus they have electronic circuits designed to limit the current... But I think this is a good enough explanation)


This is the answer. Voltage analogous to pressure and current to flow. Resistance is just resistance to flow. Like a wheel placed in the path of the water. High resistance is a wheel that's hard to spin, low is a wheel that's easy to spin. If you place a hard to spin wheel in the path of low pressure (voltage), it won't spin at all. High pressure (voltage) will spin it. The detail that everyone misses is the actual reservoir of water behind the pressure (that's akin to capacitance or just energy). A static shock is super high pressure so it spins the wheel, but there's no volume behind it, like a reservoir that's really tall but super skinny (think a long vertical straw filled with water). As soon as current begins to flow, the voltage drops away to almost nothing. The magic formula for lethal shock is enough pressure (voltage) to spin the wheel of a human body's resistance with enough flow (current), while maintaining that voltage for long enough to kill the heart. Turns out these transformers are perfect for that.


A car battery can deliver 800 amps, which is a massive amount of current. But, it’s at 12 volts so the energy can’t cross your skin into your body and into the ground (unless you have an open cut and wet feet). A taser is the opposite - it’s output is 50,000 volts but at an extremely low current. So the voltage is high enough to go through you to the ground and seize your muscles, but with a tiny amount of energy so not much damage is done. A typical household circuit can provide 15 amps at 120 volts to the input side of the microwave transformer. Enough for a painful shock but likely no injury if you are dry and wearing rubber soled shoes. If the output of the microwave transformer is 2400 volts, we can calculate the current will be 0.75 Amps. This combination is so deadly because the voltage is high enough to go straight through you like a taser, but with 100 times more energy which stops your heart and starts to cook you from the inside. TLDR: Amperage is the amount of energy, voltage is how far it can go through you. Very High voltage, very low current hurts but isn’t dangerous, very high current and very low voltage won’t go through you, high voltage with medium current is deadly.




For volts and amps, you actually need both. People oft repeat that "current, not voltage" kills, but current without voltage won't do anything. Think of voltage as "speed" and current as "mass". A pingpong ball moving at 100 kph probably won't kill you. A baseball at the same speed will do some damage. A bowling ball at the same speed will destroy you. At the same time, a bowling ball thrown by a 6 year-old kid might not do anything more than scuff your shoes.


You only need a few milliamps to stop the heart but our skin isn't very conductive so you need more volts to overcome that resistance. Between our hands is about 100k ohms so 2kV would deliver the 20 milliamps where 120 would only deliver about 1 milliamp. It's also why water is so dangerous because it destroys that resistance and the voltage needed drops considerably. She also commented on "residual switches". What she was talking about was GFCI circuits. She's right those help protect and a transformer prevents that from functioning properly. However, GFCI are usually only found around water. Kitchens, bathrooms, and outside.




The basic relationship is defined by Ohm's law. Voltage (volts) = Current (amps) x Resistance (ohms) The resistance of your body can vary depending on what path the electricity takes through your body. The contact points are the biggest variables. Are your hands dry and calloused (high resistance)? Are they sweaty or have an open cut (low resistance)? Another variable is in the power supply of what is causing electrocution. A stun gun produces a high voltage, but it cannot sustain it. It is pulsed. If the power supply is strong enough to maintain voltage while drawing current, it can be especially harmful. Low levels of current can be deadly if the current travels through nerves related to your heart. It can cause arrhythmic spasming of the heart called fibrillation. The heart spasms rather than pumping. A defibrillator could be used to "reset" the heart into normal rhythm. A second danger is lock-down or clamp-down current. That will cause muscles to lock up so you involuntarily grip what is electrocuting you, and you can't voluntarily let go. This also can prevent breathing. With high currents your body basically becomes a heating element like the coils of an electric toaster. Your skin burns and your core temperature rises. You're pretty safe with little gadgets like phones or hobby programming boards like an Arduino. Don't mess with house wiring if you don't know what you're doing. Also, don't rig up transformers to burn wood in general. If it can burn wood, it can do the same to a person. It is like any power tool. Please be safe.


> and questions YouTube's negligence in allowing them to be promoted and monetized. Let's not be too harsh on Youtube, they're very busy removing videos and handing out content strikes for photoshopping a cucumber next to someone's face, and finding new and creative ways of justifying how QuantumTV is not ban evading and how they can't do shit about off-site community guidelines violations that only exist in the form of screenshots (while demonetizing that one guy's entire channel for off-site "community guidelines violation" that only exists in the form of screenshots).


They're apparently too busy to figure out how to detect some of the most obvious spam. You can come up filter rules that would get rid of it less than a minute, but YouTube seems to have stopped trying. They have the best spam system in the business with Gmail. Surely they could detect spam that always uses the exact same wording, like "finally it's here" or similar. And there are patterns in the links themselves as well. And usernames. And use of certain emoji (e.g. those numbers). It's as bad as Disqus used to be, and they basically have no actual spam protection and depend on moderators and homemade bad word filters.


I'm glad I saw this, I have a small wood shop in my garage and was thinking of trying it. Watched a few videos, seemed straightforward enough to handle. This video might have saved my life.


My grandfather is a retired electrician and now a woodworker. He’s been doing this for years with his own built machine, it has cut off switches and a pedal so if his foot comes off it the power switches off automatically. He will never ever ever let anyone use it or show them how to make it, it’s just way too dangerous. He’s 84 now, knows what he’s doing and if he dies he’s lived a life! Super dangerous shit but his woodwork is lush




I love her so much!!! Her craft/hack debunking videos are almost as good as her recipes lol, and she almost always actually does them (obviously not this one, but others) to show how they don’t work, or don’t work as advertised, and then she shows you how to actually get the final product of the hack. Made her yogurt mousse raspberry dessert twice, and it’s been a hit both times. Actually made it for Valentine’s Day this year and my bf LOVED it. Simple, well written, and absolutely fucking delicious.


Great to see someone covering this stuff. Its one of those unknown things, which looks cool enough that a lot of people will want to try it, but the physics behind it is easy enough to skip over that it *will* kill a bunch of people. Kinda like the whole pod-eating situation, but tbh I think this one is even less obvious and more fatal (making it even more dangerous) Youtube really need a policy, like she said, warning about the dangers. If they already have such a thing for pranks, they can do it for DIY projects as well. Maybe a few of the victims & widows left behind need to kick up a legal storm with YT to make that happen... Very concerning stuff.


This was 100% on my list of things to try, and I can definitely be a bit too sure of myself with these things too. This was honestly a really good reality check for me


Anyone telling people to take apart a microwave should be banned flat out. If you know what you’re doing you don’t need YouTube. Even then the things cost almost no money. Not worth fiddling with.


I'm not an electrical engineer. But I know enough to be scared of the power delivery unit of a box that can cook my food in one minute.


Thanks for removing the dislikes, Youtube 👍


"This video has been removed for violating YouTube's Terms of Service" Oh for fuck's sake


YouTube really gotta get their shit together on this.


They really should on a LOT of things - still, will they do anything about it? No...


Now now, they've removed the dislike button so you have even less of an idea which tutorial videos contain dangerous advice that will kill you. Problem solved!


And if someone (or multiple people) even comments on the video, "Don't do this, it killed my husband!!!" that only boost the video in YouTube's algorithm...


And can't the video owner remove comments too


Restore dislike button 2022


Ehh idk. All of the wood burning tutorials I've watched had no dislikes, so they must be fine, right YouTube? :)


Was about to go off lol. Really had me in the first half


Bigclive.com (electrical engineering type) did a great video on this. https://youtu.be/FBeSKL9zVro Explains exactly why it will wreck your shit. tldr..it's the same voltage as an electric chair and on a closed loop so your RCD wont trip.


Can we please just have the dislike button back?


Life Hack: Instead of doing an electrical fractal, purchase a laser cutter for $300 and just engrave a fractal onto the wood. You can defocus the laser to create scorching.


The video's been removed. Does anyone have a mirror of this?


If you didn't read "Ann Reardon" in Ann Reardon's voice, you're a liar.
