(9:38) this spoon potentiometer is one of the best physics demonstrations ever!! You can see the wire getting hotter when there's less resistance, and you can conclude that more current flows through
sure ohms law does work here but for a given temperature. A wire of a given length will have a specific resistance and this resistance is a function of temperature so a thermal runaway will result in resistance runaway till the wire breaks.
As an industrial electrician i love the way that im still entertained by your antics even though I can see whats about to happen. If these vids were around 25 years ago i would have been doing all this in my teens. Great content

A mild mannered engineer accidentally electrocutes himself one too many times? We are basically watching an extended supervillain origin story. I’m here for it.
A story that has been going on since, what, 2012? I forgot how long Electroboom has been making videos, nor I cant remember when was the ESD video was. Point is, it has been a long time (or short depending on yoir standards)
If you watch his videos from the perspective that everything that happens is intentional, (which I'm pretty sure is the case) you'll realize that Mehdi is a legitimate genius. Seriously.
i think neodymium is much more resistive than copper it will heat up much more especially in the use case of this video with high current and hot stuff around rechargeable batteries or just batteries in general isnt a good idea
If you pass current through the casing of those magnets, be aware of the heat that this current would generate, and make sure that the magnets won't reach their Curie temperature, at which they'll lose their magnetic property. Best of luck to you.
@@ozonesama Oh neat, I didn't know about that! So how gradual is the degradation before that point? I guess what I'm asking is if magnets are mostly fine until a certain threshold and only tend to stop working above that point, or if long term low grade heat will decrease the effectiveness a lot too?
@@idontwantahandlethough It depends on the materials involved, I guess? I saw in that video ( ruclips.net/video/rOgGJaO5C00/видео.html ) that Nickel could rapidly switch back-and-forth between ferromagnetic and non-ferromagnetic, and if you know how MiniDiscs used to record data, it used a laser heat source, so it can be a very quick process, once that material's Curie temperature is reached. If you stay quite bellow that temperature, I don't think that, even by repeated prolonged exposure, you'd loose magnetism.
I hope you know you're the inspiration I needed to go back to school and learn to be an electrical engineer. Your work is awesome, and your affect on people is even greater. Thank you for the entertainment and education you continue to provide!

Real talk im a grown adult and even I want to buy and put together a couple things from kiwico. They may be for kids but ngl it looks really fun and I love science stuff.
You forgot to list the mica paper among the interesting parts a broken hair dryer has. The mica can resist temperatures well over 200 °C and is electrically insulating. This combination makes special enough to make noteworthy. If you ever need a structural element in your heater design, mica is a good choice.
@@itzfuazz4198 This is an issue with all refractory materials, so it's a given. From silica based bricks you get silicosis. Famously, asbestos causes asbestosis. Refractory mortar is acidic and burns you lungs and eyes. Ceramic wool is carcinogenic. And so and and so forth. If you're engaged in this kind of hobby, it's good practice to inform yourself of material hazards. I, for one, think that it'd been safer for Mehdi to make his foam cutter with the mica. What kind of plastic is that clamp made of? Does it gas out formaldehyde when it's getting burned by the hot wire? You see, it's easy to overdo it with the safety cautions with just about any material. Even water can be toxic, if you drink like 3 gallons of it at once. And people have done it.
@@JoshuaNorton The wire will conduct heat slowly to its outer ends wrapped through the plastic holes but it isn't heated by current farther out than the leads are attached. But yeah, I'd get a hacksaw frame and come up with some kind of insulator to mount the wire onto it with.

7:30 -The fluid dynamic effect is: if a Fluid gains kinetic energy, it must lose pressure...so the smoke is "pushed" by the air at atmospheric pressure into the tube, which is at a lower pressure due to the airflow inside.
In prison in the 1990s I once harvested nichrome wire from a wirewound resistor from a broken CRT television. Then used the nichrome wire to build a soldering iron. Then I could easily soldier televisions I was repairing. 99% of the time when the televisions broke it was an electrolytic capacitor in the vertical or horizontal deflection circuits. You could touch a working capacitor to the ones on the circuit board without removing the old ones and when you found the right one the picture would work properly. Then remove and replace the bad capacitor. This could be done without soldering, but then sometimes the picture would go out again and the owner would have to jiggle the television. After awhile jiggling would not fix the problem. Soldering the capacitors in place worked much better. I usually charged 3 bags of coffee, about $8 to fix another inmate's television. Another benefit was it provided me an extra unspoken level of protection. Since I was the only person who could repair electronics in my housing unit, mostly televisions, radios, and headphones, the other inmates didn't want anything to happen to me. Also I gained some trust and respect from other inmates since this was 100% illegal, but the guards never found any of my parts or tools. I had a bag of capacitors, a hex wrench to remove the bolts to take apart the televisions, and the previously mentioned soldering iron. It also helped that I weighed 235 pounds solid muscle from lifting weights 6 days a week.
The "some fluid dynamic effect" may be the Venturi effect, increasing fluid flow speed drops the pressure , lower pressure in the tube lets atmospheric pressure outside the tube force the smoke into it...then again what do I know, I'm also an electrical engineer ;)
I'm not sure about the technical defintion of the venturi affect, or anything, but I can say for sure the root cause is the boundary conditions of the tubes. At the point where the inner tube discharges into the outer tube, you have fast moving inside flow, butting up against slow moving outside flow. The velocity of the flow can't change instantly, so you have a gradient across the edge, so they outside cannot be zero, it must have some greater-than-zero flow rate to satisfy the boundary conditions. Also, fast moving air has an inherently lower pressure, which can also work to 'pull' the air in through the outside tube. These 2 ways of looking at this could be mathematically identical, they are the same thing from 2 perspectives, or they may both share some portion of the force for the flow.
"Sucking" device based on a Venturi effect is called aspirator or vacuum ejector, or simply ejector. For example sandblasting machines suck sand just like that.
Mehdi, I love how you take things apart to see how they work. I feel like that kind of curiosity is something we all need to embrace and encourage, particularly among kids.
Years ago I repaired the fan speed control resistor in my 1985 Honda with some surplus nichrome wire I had salvaged from some appliance that died. The fan speed had two open wound resistors wired in series . one resistor measure .25 ohms and the other .50 ohms. I was able to make new resistors and replace the two broken ones. I wound the nichrome wire around a nail then slid it off and opened the coil so the wire didn't short out on itself. Worked like a charm. And this is why I salvage anything that could come in handy some day.
I just love how ElectroBOOM is not only an amazing electrician and content creator, he also seems like such a lovely father and has fun with his family while still entertaining millions around the world! big ups to the one and only!!!
Would love to see a series of videos on CRTs. I'm interested in building a CRT from scratch. While I've researched the topic I would love to have more information on how to control the beam, how to determine the voltages needed for deflection, what temperatures are required for the heater, etc... You do such an excellent job of explaining things that a video or series of videos from you would be beneficial!
sometimes when the water heater bill not working, I use it as a water heater after I fill the bath and get in. Honestly great and cheap. You should definitely try it!
That foam cutter looks extremely interesting as someone who builds RC foamies. The typical storebought foam cutters are usually a rod that makes it extremely hard to do anything but straight cuts cleanly.
"Some fluid dynamic effect" is called "entrainment". It's demonstrated nicely with a Dyson fan. These things are ridiculously expensive though, and I'm not sure why, because they're also highly "planned obsolescent". I know this because I found one in the trash and fixed it. Basically it is made in such a way that a user couldn't clean out air filters when they got dirty. The air flow is eventually reduced to near zero and then it hits the trash can. In order for me to get to air filters I had to un-solder the 12 wires going to the control PCB and solder them back on after I removed the old filters. I didn't bother replacing them, - as they were made from foam (!) I mean you charge in excess of $400 for a fan with air filtration and you're too cheap to put a decent HEPA filter in it! Now it's just a compressor powered fan (and it was always just a fan, foam that mattresses are stuffed with is no air filter. So, if you're planning on wasting your hard earned $ on a Dyson fan, - now you know what kind of environmentally damaging SCAM you're paying for in order to dazzle your friends with a fan that supposedly has no blades (yeah right, that compressor inside is bellows-operated by little elves) . You're welcome. 😉
You can make a foam cutter with a transformer from a old boom box, a dimmer switch to control temp. And I used kanthal wire for the cutter. I made a top out of some 2x4 and ply wood with and a brace to hold the wires with pvc. Used some other minor parts (screws and such). Works great for making foam forms to do aluminum casting
Mehdi, I honestly believe you are one of the very smartest science comedian out there. This here video was pure genius. The depth of your work does not go unnoticed.
Dear mehdi .. I am writing to you from Italy 🇮🇹 I have been following you for years now and every time when I see your videos I laugh out loud .. In Italy with your facial expressions your mimicry you could have been a comedian and success was guaranteed .. Come to Italy to visit us ..

I made a smoke generator with hairdryer nichrome wire wrapped around a piece of thick wick material which was soaked in mineral oil. It creates a thick white smoke for use in diagnosing leaks.
Once you’ve tuned your power for your engraver, you can just make a battery pack with a switch! And if you know you can use different settings with different materials, you could use a pot or microcontroller for variable settings [the MCU option would be better for many variable options or if you wanted power monitoring too]
7:36 This is due to the Coanda Effect along with the Bernoulli's Principle, which tells us that if we have a pressure difference with high and low pressure air, the high pressure air will push down towards the low pressure air, thus creating a vacuum. This is best seen on aircraft wings, where the shape of the wing creates high and low pressures of air. The top of the wing creates high pressures and the bottom of the wing creates low pressures. The high pressure air pushes on the low pressure air, thus creating lift. I would like someone with a bigger brain than me to correct me on this because I'm mostly better at mechanical engineering, not fluid dynamics. Another thing I found. Due to something called viscosity, air is sticky. And so it likes to move things along its path. The enclosure of the tube that the fan is inside can also help. The pressure difference between the outside and inside of the tube can create vacuum.
I use Coanda effect and Bernoulli's principle to cool my room right now. A fan is blowing air out and into the hallway through partially open doors (maybe 25 - 30cm open) as new air is being pushed in through the window because of pressure difference. Blew my little brother's mind away. Edit: it's midnight rn and it's way colder outside, wouldn't do this in the middle of the day when it's 30°C+.
@@yegfreethinker Well, most people call it the Bernoulli's Principle. I'm pretty sure you're getting confused between Venturi's Nozzle (Which uses the Bernoulli's Principle) and the Bernoulli's Principle.
I've only stumbled onto your video's two days ago and i've not been able to stop watching. thank you, you have made me want to expand my mind and learn something new. thanks again made my 41st birthday today more interesting

Also, fast moving air has an inherently lower pressure, which can also work to 'pull' the air in through the outside tube. These 2 ways of looking at this could be mathematically identical, they are the same thing from 2 perspectives, or they may both share some portion of the force for the flow.
"Sucking" device based on a Venturi effect is called aspirator or vacuum ejector, or simply ejector. For example sandblasting machines suck sand just like that.
In high school, I tried making foam cutter without adding resistor.
It turned into lightbulb.
Mehdi, I love how you take things apart to see how they work. I feel like that kind of curiosity is something we all need to embrace and encourage, particularly among kids.
1:57 Right.....😅
6:34 OK then...🤣
If I destroy my wife's hair dryer and she doesn't kill me these experiments will. 😂👍
Years ago I repaired the fan speed control resistor in my 1985 Honda with some surplus nichrome wire I had salvaged from some appliance that died. The fan speed had two open wound resistors wired in series . one resistor measure .25 ohms and the other .50 ohms. I was able to make new resistors and replace the two broken ones. I wound the nichrome wire around a nail then slid it off and opened the coil so the wire didn't short out on itself. Worked like a charm. And this is why I salvage anything that could come in handy some day.

I just love how ElectroBOOM is not only an amazing electrician and content creator, he also seems like such a lovely father and has fun with his family while still entertaining millions around the world! big ups to the one and only!!!
This guy is a genius teaching applicable electronics with comedy and something everybody has at home making it seem easy enough.
Electroboom is the best guy in RUclips of talking, building, and surviving of his electric stuffs.
"Wood is not fire resistant"
I have never heard words spoken so truly in my life
Would love to see a series of videos on CRTs. I'm interested in building a CRT from scratch. While I've researched the topic I would love to have more information on how to control the beam, how to determine the voltages needed for deflection, what temperatures are required for the heater, etc... You do such an excellent job of explaining things that a video or series of videos from you would be beneficial!
There is a guy on RUclips who made his own clock crt, maybe check out / comment on his channel might point you in the right direction
11:38 it sounds like a High Five on High Voltage
I'm sorry that "Suck Off" joke was so funny I have no idea what exploded at 6:35, rewinding! ❤️
sometimes when the water heater bill not working, I use it as a water heater after I fill the bath and get in. Honestly great and cheap. You should definitely try it!
"First I need a piece of fire resistant material... A stick maybe?" *stick catches on fire because its made of wood* "Oh. Right. Wood is flammable."

Can’t wait to try my new hair cutting 💇♂️ foam dryer 👌
could be useful in your Liberty costume, a little touch up here and there ...
6:05 Mehdi just made the Taser tree
That foam cutter looks extremely interesting as someone who builds RC foamies. The typical storebought foam cutters are usually a rod that makes it extremely hard to do anything but straight cuts cleanly.
That's what I was thinking
"Some fluid dynamic effect" is called "entrainment". It's demonstrated nicely with a Dyson fan. These things are ridiculously expensive though, and I'm not sure why, because they're also highly "planned obsolescent". I know this because I found one in the trash and fixed it. Basically it is made in such a way that a user couldn't clean out air filters when they got dirty. The air flow is eventually reduced to near zero and then it hits the trash can. In order for me to get to air filters I had to un-solder the 12 wires going to the control PCB and solder them back on after I removed the old filters. I didn't bother replacing them, - as they were made from foam (!) I mean you charge in excess of $400 for a fan with air filtration and you're too cheap to put a decent HEPA filter in it! Now it's just a compressor powered fan (and it was always just a fan, foam that mattresses are stuffed with is no air filter. So, if you're planning on wasting your hard earned $ on a Dyson fan, - now you know what kind of environmentally damaging SCAM you're paying for in order to dazzle your friends with a fan that supposedly has no blades (yeah right, that compressor inside is bellows-operated by little elves) . You're welcome. 😉
5:59 please don't die😂
The "HA! That's my daughter!" REALLY MADE ME LAUGH HAHAHH she's just like you! XD
Electroboom is one villain origin story away from becoming a mad scientist
he even has the name
Electroboom as Doofenshirmtz
You can make a foam cutter with a transformer from a old boom box, a dimmer switch to control temp. And I used kanthal wire for the cutter. I made a top out of some 2x4 and ply wood with and a brace to hold the wires with pvc. Used some other minor parts (screws and such). Works great for making foam forms to do aluminum casting
This man’s transitions to sponsors are uncannily seamless.
Now that's how you do sponsored adverts! Also a standing ovation for putting it at the end of the video
6:58 ...doesn't get much truer than this in our modern age!
Exactly. But since he said it with a touch of humour, people dont tend to take it seariously..💡💡
Plenty of cool ideas! Now try make something to blow warm air on your hair to dry them

I made a smoke generator with hairdryer nichrome wire wrapped around a piece of thick wick material which was soaked in mineral oil. It creates a thick white smoke for use in diagnosing leaks.
Once you’ve tuned your power for your engraver, you can just make a battery pack with a switch! And if you know you can use different settings with different materials, you could use a pot or microcontroller for variable settings [the MCU option would be better for many variable options or if you wanted power monitoring too]
7:36 This is due to the Coanda Effect along with the Bernoulli's Principle, which tells us that if we have a pressure difference with high and low pressure air, the high pressure air will push down towards the low pressure air, thus creating a vacuum. This is best seen on aircraft wings, where the shape of the wing creates high and low pressures of air. The top of the wing creates high pressures and the bottom of the wing creates low pressures. The high pressure air pushes on the low pressure air, thus creating lift.
I would like someone with a bigger brain than me to correct me on this because I'm mostly better at mechanical engineering, not fluid dynamics.
Another thing I found. Due to something called viscosity, air is sticky. And so it likes to move things along its path.
The enclosure of the tube that the fan is inside can also help. The pressure difference between the outside and inside of the tube can create vacuum.
Venturi Effect actually
I use Coanda effect and Bernoulli's principle to cool my room right now. A fan is blowing air out and into the hallway through partially open doors (maybe 25 - 30cm open) as new air is being pushed in through the window because of pressure difference.
Blew my little brother's mind away.
Edit: it's midnight rn and it's way colder outside, wouldn't do this in the middle of the day when it's 30°C+.
@@yegfreethinker Well, most people call it the Bernoulli's Principle. I'm pretty sure you're getting confused between Venturi's Nozzle (Which uses the Bernoulli's Principle) and the Bernoulli's Principle.
@@suspense_comix3237 it's literally the Venturi Effect, as a special case of the Bernoulli Principle
"hi, today we want to get into the amazing world of an hairdryer :D!"

I've only stumbled onto your video's two days ago and i've not been able to stop watching. thank you, you have made me want to expand my mind and learn something new. thanks again made my 41st birthday today more interesting
@08:40 - Finally! (I was mentally shouting that at him at least twice before)
I love how even mehdi is suprised that he made something we can do at home
And yet *still* managed to hurt himself with it! :)
3:51 Technically, *anything* is a fuse if you try hard enough.
I can use air as a fuse?
Even PC's can be fuse to. Just put you game graphics on the highest setting.
@crazysaturn0805
Or just remove the main power supply and stick straight 110v or 240v on the board. It'll protect your outlet from accidental activation and creates bonus forbidden fog too and fireworks just for fun. Lol
@@crazysaturn0805you mean power resistor?

Hmmm yes it looks like it's made from material
wow the duck was amazing!! great video as always!
10:33 is the funniest part because his eyes when he says "while you can use it to dry your hair." And then he got partially angry when he said "IF THERE WAS ANY!".
Reminds me of the wood burning pencil I had as a kid... Its basically a soldering iron with a brass tip to burn into wood. Never used it.. lol
Lost it when you went full circle to putting the fan and the resistive wire together and "wait, that's just a hairdry-"
4:09 reminds me when i put same same wire in two sockets of switch board ! Pufffff 💥 ! 😂
This is the only RUclipsr who actively electrocutes or burns himself almost every episode and makes his content interesting electroboom is my favorite RUclipsr
