Re: bathroom outlet puzzle. Older houses were wired with switched outlets on the same circuit as the light. That made it less likely for a person to leave things like hair dryers on and walk away, creating a fire hazard. This looks to be one of those houses, but the guy accidentally wired in the outlet parallel to the switch. It is possible that the former fan switch was sort of like a main switch for the whole bathroom, turning everything on/off with the former mirror light switch also controlling the outlet.
8:40 This is the exact reason those extension spools come with "DO NOT OPERATE SPOOLED UP" written somewhere on them. 1: Cable can't dissipate heat, because it's all coiled and packed up. 2: Induction. Makes things warm. For reference see induction stoves or induction forging. Run a kW or two through that spool and best case you'll get is an un-despoolable spool, because the insulation will just melt and become one. Worst case is a quick visit from the fire department.
@@Owen_loves_Butters It does in this case, because there's not one but three coils. P, N and PE. The magnetic field produced by the AC in P and N will most certainly heat PE by induction. And they'll probably also heat each other due to the fact that their magnetic fields always face opposite from each other.
@@JeskidoYT MWBC is a “ multi-wire branch circuit”. It’s when two circuits share the same neutral wire back to the panel. The two hot conductors are 180 or 160 degrees out of phase so the neutral can’t be overloaded. Look it up and you will find plenty of diagrams. In this situation the two circuits that share the neutral will appear to act bizarre if the neutral connection is lost hence why I think that’s what happened in the bathroom. In the U.S. and Canada it’s unusual to have the bathroom lights on the same circuit with the outlet. But they could absolutely be two separate circuits sharing a neutral aka MWBC. Hope this helps.

8:29 I believe the image right below that is showing how much current was involved.. it says 3120 W @ 240V, which would be about 13 amps. The important point is that the cord is all coiled up, though. Many (especially cheaper) extension cords are rated for a certain amount of current, but that rating is assuming they are operating out in open air, so the heat can be dissipated by the air around them. However, if you coil them all up tightly like this, they can accumulate a lot more heat inside that tight package (!). Always be wary of coiling up extension cords like this, as bad things can happen like this if you're not careful.
I believe that the coiled up cord behaved as an inductor here and the wire got hotter as it normally would thanks to the inductance . Normally an outlet of 240V is run thorough a 16 amp fuse. The fuse breaks long before the wire heats up like that. Besides those extension cords are rated to 3.6kW
@@giaining no, the extension cord did not behave like an inductor. This is because the cord contains two wires, each with current of the same magnitude flowing in the opposite direction. So the magnetic fields created by each wire cancel are close enough that they cancel each other and the inductance is removed. Also, even if it did act like an inductor, that would not increase the amount of heat the cord produced. On the contrary: an inductor in an AC circuit reduces the flow of current due to its impedance, meaning that if the coil of extension cord acted like an inductor it would actually heat up _less_ .

Same, though I'm on my final undergraduate year. AvE and BigClive also played a significant role. I need to get an oscilloscope though. Been looking for a cheap second hand one.
8:35 this is why it is strictly required by safety instructions to fully unwind extension cord before loading. It has poor heat dissipation while winded, which can lead to overheating and melting.
At 8:31 they show only the rating for the fully extended cable. What they dont show is the rating for the coiled up one, which is much lower because the cable drum creates a coil. And we all know what fun you could have with a wire coil
It's not really a coil, because all magnetic field generated by one of the wires get negated by other one. It's just heat. Long rolls of copper have some resistance, with high current flow there is heat generated and trapped inside.
To add to this: Those reels are mostly rated at around 3300W when unrolled, but only 1000-1500 when rolled up. And i have seen people using a mitersaw, anglegrinder, drill and weedwacker when fully rolled up.... way overloaded even if it was unrolled.
@@monad_tcp Nope, twisting is only effective on close range. It is just a simple way to keep the wires close together. For field cancellation it is not strictly necessary.
Can you do long sparks in a smoke field and if we could see the turbulence causing the sparks to shift when jumping longer distances? It would be interesting to see if this would allow us to see this.
The "Shocking Toy" that was showed at 6:00 is a common thing to be made at elementary schools in Finland. But rather than getting shocked, it lights up an LED.
Wikipedia says 1953, but it's one of those ideas that are so simple that it probably has been independently reinvented dozens of times. Them adding the shock aspect is probably not too surprising either. Medhi was probably aware of this though. Pretty interesting that this thing could have been invented during the 1830s, but seemingly just wasn't.
Carbon arc torches used to be a thing, basically an attachment to a stick welder that used the arc from two carbon sticks to provide the heat for welding.
Sure, but the weld in the video had extra material from a steel electrode. (It didn't just melt together the two existing bits of metal) Looks like it had flux on it too.
@@AndyLundell It was flux from an electrode (i.e. An electric arc welding electrode) there is no way that he could have welded that without adding material. Total (pathetic attempt) fake -btw I used to be a welder before retiring.
@@Basement-Science Arc welders don't work on high voltages, only about 20 volts. They need high amperage. Two twelve volt batteries in series are more than enough voltage to weld. Some off roaders carry a few welding rod and a welding cable set up to work off auto batteries jumped in series. I've seen a tie rod, broken on the Rubicon, that was repaired with a craftsman end wrench, welded with borrowed batteries and an emergency welding kit, trailside. This graphite stinger video is not real though, for sure, he chipped off slag from a coated rod.
8:31 that happens for welders... You're not meant to weld with the entire wire still rolled on the spool. You're meant to pull it out and spread it evenly on the floor so it cools down. Otherwise, the heat will never dissipate in time, and the insulation will start to overheat. Saying this because it happened to me the first time I used a stick welder.
Is this satire? Welding wire isn't insulated, and the electrode is in the gun so the wire that isn't being immediately used doesn't get hot. And stick welders don't use wire, they use a... stick. Or am I having a terrible misunderstanding and you mean the welder power cable? Have never needed to pull out cable when welding, I guess I'm lucky.
@@owenkegg5608by "wire" he could mean that the welder had a long cable that's spooled up for storage, or a spooled extension cord. Or the cable to the handle or ground clamp. I can see one way you could have a problem with the wire in a MIG welder melting. That would be if the wire is grounded somewhere between the handle and the spool. Then current would flow back through the wire inside the guide in the cable back to the machine. I bet that would get quite hot. Telling a noob MIG welder to unspool the wire _would_ be a nasty prank, though 🙂
In the UK at least most cable extension reels will actually have two max current ratings printed on them. One for wound, one for unwound. The decent ones have a thermal cutout too, because users are idiots
Hi Mehdi, actually graphite welding does exist in industrial applications. It is called graphite electrode welding. The graphite is used only as electrode, where external material (filler) is added during welding. It is highly uncomfortable method, because the arc ignition is extremely loud and bright. Never the less, graphite welding is actually real (usually 270+ Amps).
@6:52 Your Wife (I assume that's your Wife the smacked you silly) is such a trooper, and your daughter is loving every second of it... Your daughter knows what's up (She was in on it, wasn't she?)...
Light switch puzzle: reminds me of a Don Martin cartoon about a plumber. "I turn on the hot water, and the toilet flushes!" Shocking toy: I seem to remember a full-sized one, maybe with lethal power, in some old TV show - perhaps an episode of The Avengers?
Pro tip: if you don't want to rip apart a battery, you can get graphite from a common pencil. Sharpen both ends, and connect both sharpened ends to a voltage source. 20 to 30 volts should do. It'll get hot and start to burn the pencil. No need to burn the whole pencil. The graphite should burn itself free in less than a minute.
you can also get large diameter graphite for artistic use or mechanical pencil refills. Artist's graphite will be much larger though. They will have some clay included for hardness though, so don't expect them to be chemistry grade or anything.
you can also use brazing rods from the welder store. They are graphite rods, often with a thin metal coating that is easily removed (dilute acid for one)
6:35 They maybe could have copied you, but I’ve also seen this kind of electric shock thing on other game shows from a while ago. I’m not sure if it’s the first, but a Japanese game show had a segment called Irritating Stick (or something of that nature), with a pretty similar device and premise, and that was from the 90s.
also, the device was featured in a Mr. Bean episode back in the 90s, the one with the school open house which ended with his Mini being run over by a tank
1:50 They make,or used to make,a soldering iron using a carbon/graphite tip. "Cold Heat",I think it was called. I got one as a stocking stuffer one year,and it was....basically garbage. Plus the brittle tips break off easily.
I remember when ElectroCute used to get very happy from receiving a kiwico toy, now she reacts like my cat when i get home from work (7:25), time flies..
Mr.Boom, The hairdryer/light phenomenon that you showed is probably because they lost a phase at their service. When you lose a phase sometimes plugging things in will backfeed the Dead phase through the neutral wire. It happens a lot and it’s usually the water heater that backseat a bunch of circuit throughout the house when you lose a phase
This sort of thing can also happen if you have split-phase power (such as is common in the US) and a floating neutral somewhere (such as if the light switch is switching the neutral instead of the hot line). Then you can get a situation where Lamp1 + Lamp2, or Lamp1 + hair dryer end up in series across the 240V between the one hot line and the other.
@@ElectroBOOM Don't know how to include a drawing in a RUclips comment, but this exact thing happened to me - lost one 120V phase, but the other phase supplied power to the house lighting/appliances through the 240V water heater. Here's a diagram that won't work unless you copy it and paste it into a document, then convert to a proportional font (like Courier): |-------HI | | water NEU -----| heater | | light | | |--------HI------| |-------HI | | water NEU -----| heater | | light | | |--------XX------|
I have had this happen at work where we had a three phase breaker for the lighting and the neutral was disconnected. but we had fluorescent lighting which made quite a nice discoshow.
I do think that hydrogen from electrolysis can be made to run a truck, The trick is to just make sure the truck is of sufficient capacity to tow a very large enough diesel generator behind it, with plenty of diesel too.
DU is very much radioactive, it's still uranium. It's just been depleted of the fissile U-235 and only has U-238, which can't make bombs explode or reactors react.
4:15 I think the original wiring was back fed . The hot went to the light then to the switches. He messed something up for sure in the light and or switch
There was a Japan-only PS1 game called "Irritating Stick" that was based on the concept of getting shocked if you let a stick touch the sides of a metal maze you guided it through. I've heard it was based on an actual Japanese game show, but was never able to confirm.
That PS1 game was a port of an arcade game (The Irritating Maze) that used a trackball connected to some air jets. The trackball added difficulty and the air jets simulated the electric shock in a safer way. But yes, I'm fairly certain the idea is much older than even that.
The graphite as an electrode I can confirm. Not the video itself there was obviously slag from an actual welding rod but I've used graphite electrodes with an old 240v Ac transformer welder to melt mostly copper. The arc it creates can melt steel but really only enough for welding unless you get some insane insulation. Edit: forgot to add you need to grab those 6v zinc carbon batteries you see at home Depot, Menards, Lowe's, ect. They have carbon rods maybe 25cm in length and 5cm diameter. I always keep them on hand and when the 6v batteries are gone the carbon rods are still useful.
I think you're off on your conversions, at least the diameter (5cm is 2 inches), and I assume you meant the total length of all 4 rods. From videos I've seen I would guess each rod is maybe 8cm long, 8mm diameter, but I've never taken one apart myself.
0:50 - Yes you CAN weld with graphite. This isn't something that's to be debated or confused about. We've done it for years. It's called CARBON ARC WELDING
The whole thing with the carbon rod is definitely possible as it isn't a new concept, before acetylene torches were commonly available they used to sell arc welders with a "carbon arc torch" attachment witch was just a holder for two carbon rods just like what you see in the video, anyway the purpose was pretty much the same as an acetylene torch so you could braise or heat up rusty hardware to get it to move, I've attempted to braise with one and it doesn't work the greatest but I also had nobody to teach me how to use it and couldn't find any tutorials on the internet.
The radioactive one left me speechless. I hope they didn't play with it a whole lot. Especially touching the container with his skin. Edit: good to hear it's fake.
As for the motor in 12:20, someone made a video showing why it is impossible but basicaly the power generated by the motor (which was running with a mix of gas and O and H) was less than the power required to separate the oxygen and hydrogen in the water.
As long as the electrolysis cycle is productive enough and ‘buffered’ by a battery, I’m pretty sure the thing will run for a good few minutes - depending on the capacity of the battery. Charging it from the generator might add some short amount of extra run time, but once the battery is dead - game over.
@@TGSankar i mean a steam engine runs on steam so I guess you can make an engine powers by water but I'm sure that it would suck and pretty much be useless
MANNN i used to watch you as a little ass kid and die laughing I forgot about this entirely!! it makes me so happy to see your channel still thriving and with a ton more subscribers. HECK YEA!
Lol 0:50 buddy just cut the video and welded it with rod instead. I gotta add carbon rods are used for taking away material. I've never seen somebody lay a bead with a gouging rod.
4:49 ? logic suggests that the resistance in an incandescent lamp (L2) is HIGH; higher than that in the control circuit in a blowdryer. and (probably) higher than that at the LED. so, is the statement at the bottom (in red) correct.?
MAKE THE CAPACITOR ALARM CLOCK ALREADY (also I have a light in my hallway that has 2 lights with escape and if you make one off and one on its gonna be off depending on witch is first )
Well carbon rods from battery are not pure graphite, they do contain flux and other compounds to improve the electrochemical cell reactions. (But that is in very small quantity) 😬
@@Vrushabh_M but not flux powder, which is a thick coating around an arc welder rod that protects the weld as it's laid down and ends up coating it, and needs to be peened away afterwards. flux just goes up in smoke in welding, arc welding flux powder coats the weld

8:35 this is why it is strictly required by safety instructions to fully unwind extension cord before loading. It has poor heat dissipation while winded, which can lead to overheating and melting.
I for one really enjoy these videos - please do more (and of course your regular stuff)... cheers
11:35 like the fact that in the voice over he also goes "AW!" just softer
12:45 MY MAN DIDNT DESERVE THAT BURN AHAHAHAHAHAHHA,
It came so unexpected, i didnt see him that pissed at the video, but that was hilarious
“See? His heart is protected! Err, ignore that the paper piece keeps burning. That’s just a visual aid.”

gotta love when you weld with graphite and somehow it not only adds metal but also adds slag
"Never become a part of high voltage circuit". Words to live by

Your floating head is absolutely hilarious 🤣 You're a legend, Mehdi.
At 8:31 they show only the rating for the fully extended cable. What they dont show is the rating for the coiled up one, which is much lower because the cable drum creates a coil. And we all know what fun you could have with a wire coil
It's not really a coil, because all magnetic field generated by one of the wires get negated by other one. It's just heat. Long rolls of copper have some resistance, with high current flow there is heat generated and trapped inside.
To add to this:
Those reels are mostly rated at around 3300W when unrolled, but only 1000-1500 when rolled up. And i have seen people using a mitersaw, anglegrinder, drill and weedwacker when fully rolled up.... way overloaded even if it was unrolled.
@@kjur18 it depends if the wire is twisted or not.
@@monad_tcp Nope, twisting is only effective on close range. It is just a simple way to keep the wires close together. For field cancellation it is not strictly necessary.
It has little to do with being a coil, it has to do with less airflow than normal.
Can you do long sparks in a smoke field and if we could see the turbulence causing the sparks to shift when jumping longer distances? It would be interesting to see if this would allow us to see this.
The "Shocking Toy" that was showed at 6:00 is a common thing to be made at elementary schools in Finland. But rather than getting shocked, it lights up an LED.
It's not a finnish thing lol, this exists everywhere and it's probably like 100 years old.
I built one when I was like 6 or so many years ago
Wikipedia says 1953, but it's one of those ideas that are so simple that it probably has been independently reinvented dozens of times. Them adding the shock aspect is probably not too surprising either. Medhi was probably aware of this though.
Pretty interesting that this thing could have been invented during the 1830s, but seemingly just wasn't.

Carbon arc torches used to be a thing, basically an attachment to a stick welder that used the arc from two carbon sticks to provide the heat for welding.
yeah you're not doing much with just 12V though. A stick welder puts out much more than that.
Yablochkov Candle used to be an alternative to incandescent lamp, before it was invented. It also worked on carbon arc.
Sure, but the weld in the video had extra material from a steel electrode. (It didn't just melt together the two existing bits of metal)
Looks like it had flux on it too.
@@AndyLundell It was flux from an electrode (i.e. An electric arc welding electrode) there is no way that he could have welded that without adding material. Total (pathetic attempt) fake -btw I used to be a welder before retiring.
@@Basement-Science
Arc welders don't work on high voltages, only about 20 volts. They need high amperage.
Two twelve volt batteries in series are more than enough voltage to weld.
Some off roaders carry a few welding rod and a welding cable set up to work off auto batteries jumped in series. I've seen a tie rod, broken on the Rubicon, that was repaired with a craftsman end wrench, welded with borrowed batteries and an emergency welding kit, trailside.
This graphite stinger video is not real though, for sure, he chipped off slag from a coated rod.
8:31 that happens for welders... You're not meant to weld with the entire wire still rolled on the spool.
You're meant to pull it out and spread it evenly on the floor so it cools down. Otherwise, the heat will never dissipate in time, and the insulation will start to overheat.
Saying this because it happened to me the first time I used a stick welder.
Is this satire?
Welding wire isn't insulated, and the electrode is in the gun so the wire that isn't being immediately used doesn't get hot. And stick welders don't use wire, they use a... stick.
Or am I having a terrible misunderstanding and you mean the welder power cable?
Have never needed to pull out cable when welding, I guess I'm lucky.
@@owenkegg5608by "wire" he could mean that the welder had a long cable that's spooled up for storage, or a spooled extension cord. Or the cable to the handle or ground clamp.
I can see one way you could have a problem with the wire in a MIG welder melting. That would be if the wire is grounded somewhere between the handle and the spool. Then current would flow back through the wire inside the guide in the cable back to the machine. I bet that would get quite hot.
Telling a noob MIG welder to unspool the wire _would_ be a nasty prank, though 🙂
@@phizc Hehehe, yeah. That would be quite a brutal hazing, especially since they would need to wind it back up after :]
@@owenkegg5608 flip the spool and run the machine at max wire speed to rewind
In the UK at least most cable extension reels will actually have two max current ratings printed on them. One for wound, one for unwound. The decent ones have a thermal cutout too, because users are idiots
Hi Mehdi, actually graphite welding does exist in industrial applications. It is called graphite electrode welding. The graphite is used only as electrode, where external material (filler) is added during welding. It is highly uncomfortable method, because the arc ignition is extremely loud and bright. Never the less, graphite welding is actually real (usually 270+ Amps).
@6:52 Your Wife (I assume that's your Wife the smacked you silly) is such a trooper, and your daughter is loving every second of it... Your daughter knows what's up (She was in on it, wasn't she?)...

that was my exact same reaction, like why he did that? 🤣
Light switch puzzle: reminds me of a Don Martin cartoon about a plumber. "I turn on the hot water, and the toilet flushes!"
Shocking toy: I seem to remember a full-sized one, maybe with lethal power, in some old TV show - perhaps an episode of The Avengers?
6:52 Mrs. Mehdi electrically shocked by one of his creations and commences immediately to thumping him. XD
The reason why the camera is always zoomed in on Mehdi is because he's entirely surrounded by fire extinguishers and defibrillators.
Pro tip: if you don't want to rip apart a battery, you can get graphite from a common pencil. Sharpen both ends, and connect both sharpened ends to a voltage source. 20 to 30 volts should do. It'll get hot and start to burn the pencil. No need to burn the whole pencil. The graphite should burn itself free in less than a minute.
Yeah but pencils are graphite/clay mixtures where batteries are pure carbon.
you can also get large diameter graphite for artistic use or mechanical pencil refills. Artist's graphite will be much larger though. They will have some clay included for hardness though, so don't expect them to be chemistry grade or anything.
@@professorfukyu744 i thought only the erasers had clay in them, but i guess there's enough graphite in pencil lead for that to work.
you can also use brazing rods from the welder store. They are graphite rods, often with a thin metal coating that is easily removed (dilute acid for one)
Or just lead for a mechanical pencil
2:16 makes me happy I'm bald now... priceless
6:35 They maybe could have copied you, but I’ve also seen this kind of electric shock thing on other game shows from a while ago. I’m not sure if it’s the first, but a Japanese game show had a segment called Irritating Stick (or something of that nature), with a pretty similar device and premise, and that was from the 90s.
Also in like every science museum ever
It's a tv show called 8 out of 10 cats. The episode is a lot older it's just that it was uploaded to RUclips a year ago
also, the device was featured in a Mr. Bean episode back in the 90s, the one with the school open house which ended with his Mini being run over by a tank
And the board game Operation from like the 70's is a twist on the concept
Explaining how Allen Pan didn't die from a heart attack was entertaining as hell. YOu should do more of those kinda things

2:16 "OMG look at that haircut, makes me happy that I'm bald now" 😂🤣🤣
Mr.Boom, The hairdryer/light phenomenon that you showed is probably because they lost a phase at their service. When you lose a phase sometimes plugging things in will backfeed the Dead phase through the neutral wire. It happens a lot and it’s usually the water heater that backseat a bunch of circuit throughout the house when you lose a phase
draw me a circuit!
But usually in bathrooms they use the black phase only and in the kitchens and laundry rooms they use both the black and red phase right?
This sort of thing can also happen if you have split-phase power (such as is common in the US) and a floating neutral somewhere (such as if the light switch is switching the neutral instead of the hot line). Then you can get a situation where Lamp1 + Lamp2, or Lamp1 + hair dryer end up in series across the 240V between the one hot line and the other.
@@ElectroBOOM Don't know how to include a drawing in a RUclips comment, but this exact thing happened to me - lost one 120V phase, but the other phase supplied power to the house lighting/appliances through the 240V water heater. Here's a diagram that won't work unless you copy it and paste it into a document, then convert to a proportional font (like Courier):
|-------HI
|
|
water NEU -----|
heater |
| light
| |
|--------HI------|
|-------HI
|
|
water NEU -----|
heater |
| light

|--------XX------|
I have had this happen at work where we had a three phase breaker for the lighting and the neutral was disconnected. but we had fluorescent lighting which made quite a nice discoshow.
there have been cars running on water since the 70s.
That riddle with the bathroom lights and the hair dryer was really interesting! I wish we could see some more stuff like that.
Just work on some electrical stuff in an old house and you will!

I do think that hydrogen from electrolysis can be made to run a truck, The trick is to just make sure the truck is of sufficient capacity to tow a very large enough diesel generator behind it, with plenty of diesel too.
13:01 it could also be a depleted uranium container... not so depleted.
DU is very much radioactive, it's still uranium. It's just been depleted of the fissile U-235 and only has U-238, which can't make bombs explode or reactors react.

There was a Japan-only PS1 game called "Irritating Stick" that was based on the concept of getting shocked if you let a stick touch the sides of a metal maze you guided it through. I've heard it was based on an actual Japanese game show, but was never able to confirm.
They blew up gunpowder instead of the contestant though.
There is a Norwegian show that's used the same kind of setup as that Jimmy Carr show as well (71 grader nord)
They used to have countertop ones sitting in bars. It didn't shock you, but it let out a blood curdling buzzing sound that would make you jump...
Can confirm, I've seen footage of the show.
That PS1 game was a port of an arcade game (The Irritating Maze) that used a trackball connected to some air jets. The trackball added difficulty and the air jets simulated the electric shock in a safer way. But yes, I'm fairly certain the idea is much older than even that.
The graphite as an electrode I can confirm. Not the video itself there was obviously slag from an actual welding rod but I've used graphite electrodes with an old 240v Ac transformer welder to melt mostly copper. The arc it creates can melt steel but really only enough for welding unless you get some insane insulation.
Edit: forgot to add you need to grab those 6v zinc carbon batteries you see at home Depot, Menards, Lowe's, ect. They have carbon rods maybe 25cm in length and 5cm diameter. I always keep them on hand and when the 6v batteries are gone the carbon rods are still useful.
I think you're off on your conversions, at least the diameter (5cm is 2 inches), and I assume you meant the total length of all 4 rods.
From videos I've seen I would guess each rod is maybe 8cm long, 8mm diameter, but I've never taken one apart myself.
I've seen people stick weld with proper electrodes connected car batteries too, so there's some reality to that clip
0:50 - Yes you CAN weld with graphite. This isn't something that's to be debated or confused about. We've done it for years.
It's called CARBON ARC WELDING
0:03 Mehdi: "THERE IS NO ENGINE THAT CAN RUN ON BURNING WATER!" Nuclear reactors:
1:55 Mehdi before he had a unibrow.
The whole thing with the carbon rod is definitely possible as it isn't a new concept, before acetylene torches were commonly available they used to sell arc welders with a "carbon arc torch" attachment witch was just a holder for two carbon rods just like what you see in the video, anyway the purpose was pretty much the same as an acetylene torch so you could braise or heat up rusty hardware to get it to move, I've attempted to braise with one and it doesn't work the greatest but I also had nobody to teach me how to use it and couldn't find any tutorials on the internet.
I've still got mine, I did some amazing (brazed) rust repairs with it

As for the motor in 12:20, someone made a video showing why it is impossible but basicaly the power generated by the motor (which was running with a mix of gas and O and H) was less than the power required to separate the oxygen and hydrogen in the water.
As long as the electrolysis cycle is productive enough and ‘buffered’ by a battery, I’m pretty sure the thing will run for a good few minutes - depending on the capacity of the battery.
Charging it from the generator might add some short amount of extra run time, but once the battery is dead - game over.

Hearing the wife almost crying with laughter is really wholesome to be honest.

i know that look in his eyes
He did already
MAKE THE CAPACITOR ALARM CLOCK ALREADY (also I have a light in my hallway that has 2 lights with escape and if you make one off and one on its gonna be off depending on witch is first )
1:09 the fact that he had to peen off the spent flux powder shows he used a welder aswell, carbon rods don't have flux powder
Well carbon rods from battery are not pure graphite, they do contain flux and other compounds to improve the electrochemical cell reactions.
(But that is in very small quantity) 😬
@@Vrushabh_M but not flux powder, which is a thick coating around an arc welder rod that protects the weld as it's laid down and ends up coating it, and needs to be peened away afterwards.
flux just goes up in smoke in welding, arc welding flux powder coats the weld
you can weld with graphite, in fact it was used before metal rods.
its still used to weld wires together if its necessary
