Every time Mehdi brings out part of a microwave, it gives me visions of his wife or children, walking into the kitchen looking to warm something up, and just finding a hole where the microwave used to be.
🤣
His wife probably has a stash of new microwaves hidden away at this point haha
Why would his wife and children want to warm a microwave up? I don't get it. /s
It gives me visions of his wife and children, walking into the house just to find a smoldering corpse where Mehdi used to be.

12:50 "The key is not to touch any voltage"
Words to live by as an electrician.
And yet you still find a way to give yourself a wake me up every now andthen. 😂
Except he doesn't follow these words either. He electrocutes himself in every video.
HV: no need to touch, I'll just break down air.
@@matthewtalbot-paine7977He dies in every video? That's a lot of funerals.
@@cancelhandles Electrocution doesn't mean death wtf you talking about.
Mehdi, you are the type of person that 150 years ago would have been leading electrical discoveries. I love your passion.
To be fair he is not in his 70s yet. Between the trio of SmarterEveryDay, TheActionLab, and ElectroBoom, we could end up with a revolution XD
@@CoffeeKillersClub We've already discovered everything...until we discover something new, that is.
13:29 , depending on the type of salt used (table salt = sodium chloride) you are probably making chlorine gas as a bi-product. Drake at styropyro makes it quite often in his chemistry videos.
Its probably just a mixture of hydrogen and oxygen. Water breaks down into hydrogen and oxygen when there is electricity in the water but he could probably also have made chlorine gas as well (if anyone wants to try and break down water, be careful the hydrogen and oxygen mixture is explosive)
@Notwhitewolf While electrolysis of relatively pure water produces basically pure H2 (hydrogen) at the cathode and basically pure O2 (oxygen) at the anode; if the water is nearly saturated with sodium chloride (the primary component of table salt), something different happens. H2 and O2 are still produced, but the O2 is mixed with Cl2 (chlorine gas) and in the water (rather than bubbling out with the gases), NaOH is produced (sodium hydroxide, commonly used as drain cleaner and in various detergents and other cleaning products).
I was just thinking this - its not boiling, its electrolysing. I wonder if Mehdi could smell chlorine. Plus, the flashes might have been sodium oxidation.
Learned this one the hard way...
@@beans9647 you gased yourself didn’t you
Mehdi: It's important to educate your audience on real science.
Also Mehdi: I set the water on fire...
The only difference between doing science and goofing around is recording your results.
@@theKashConnoisseur Beautifully said.
...on a failed suicide attempt xD
Water in the fire WHY
it was probs the oxygen and hydrogen created with electrolysis combusting
Love how the science youtube creators have 0 real beef. They all just point
to the expert of each topic.
Science is like that. The truth is the truth. It's just a matter of finding people who respect the method.
@@hgbugalou facebook wants to know your location
They're here because they're passionate about what they do and because they want to educate people on their particular fields. A stark difference to all the people who are just on here to try and get famous.
That and I'm pretty sure half of them are autistic as shit.
@@hgbugalouthe only real competition between creators is who can explain the science better. Since understanding is subjective and based on the audience everyone really wins in the end since creators get paid to stay innovative and people get to learn science from many great teachers.
@@Ready_Set_Boom When someone gets something wrong and have to be corrected, this drives traffic between them. Which is a win for everyone involved.

I love how mehdi just says "who cares about the rail gun this is more fun" and proceeds to do something he knows is dangerous for a laugh
Every day life threatening electronics just don't phase him anymore
Meh... It was only 30v dc
@@nathanaelcadman-neu410 Right. Far from the most dangerous thing he's played with. Let him have a bit of fun. xD
If I would be in his shoes, then I would do the same. It's too much fun to not do it.
I like how 30V DC is not dangerous anymore in this context. Also fire and health hazard from the electrolysis (H2 + O) and sparks (circuit arcs)
6:00 Plastic pppppplate thingy.
5:31 😂😂😂😂😂😂
I think him accidentally making a battery is the first thing to make me laugh out loud! Always love you vids
Making an accidental battery is more impressive than an accidental antenna.
I accidentally made an antenna the other day, I ran a 10Mhz CPU in a breadboard without any ground connection and the loop the CPU was doing created fun interference, the clock signal of the PLL just escaped, accidental radio transmitter
I doubt it was accidental. That spoon wasn't suddenly introduced accidentally ;)
That made me laugh out loud too, hahaha. Such a good moment.
I've never been so afraid for someone else's life. Absolute mad lad. You're a legend Mehdi. You should make electric/reusable fireworks for Canada Day.
If you think he's nuts, you should check out Styropro. That guy is certifiable.
Great idea!
I dunno, this was tame compared to ua-cam.com/video/4opcNLIQqt4/v-deo.html&feature=shares.
I almost didn't make it through that one, my stomach was so tight. Way scarier than a horror movie lol!
Also I'm glad that @Integza has started wearing goggles occasionally at least! XD
@@WarttHog This is the video of his that led me to his channel. ua-cam.com/video/TwIvUbOhcKE/v-deo.html
Also found out him hurting or shocking himself in his videos is sort of a running gag of his. I happened on him around the same time as PhotonicInduction (I think that is the name of the channel) but he has been having a lot of personal things and dose not upload as much anymore.
When I go to the pool with my friends
3:20 and this is why PC water cooling uses distilled water and is also recommended to be flushed every now and then since the water will over time eat away the metals in the loop and make the water conductive again. ofc flushing cant be done on AIO since those are most of the time a closed loop
2:30 this is used in genetic and proteomic testing using electrophoresis gel. The protein or gene strand is put into a gel with varying degrees of density as a current runs through the fluid and pulls the materials through. Based on the length of the genetic strand it will stop moving at a certain point in the fluid because of friction and you can use this to see if your sample has a gene strand or protein that matches your control.
It works on the principle of attraction and repulsion. DNA is negatively charged and thus gets attracted to positive terminal. Here in the video, he is working with electromagnetism and eddy currents.
Excellent. Water *is* slightly diamagnetic so you could possibly get it to move if you used a massively powerful (probably superconducting) magnet driven by half a power station. I'm sure there's a handy one under Mehdi's desk somewhere ...
It's time to disassemble the big microwave in the house
He probably stole the Red October from the CIA or something. That had a magneto-hydrodynamic drive in the book/movie
So just throw it in a particle accelerator?
I mean, scientists made a frog float with very powerful magnets, so its not impossible.
ah that was the word I was trying to think of "diamagnetic" I was like "magneticphobic?" lol.
I know it's a part of his schtick and he knows what he's doing but watching someone dunk a microwave transformer in water while holding it still gives me that vertigo sensation in my stomach. (even without the secondary winding)
very salty water
@@Ass_of_Amalek mmmm salty
In 6:10? I think that one is really unexpected.
Yeah, a lot of times you can see it coming from a mile away, when he's holding something in a weird way, or placing his finger on a metal part (like he did when he shocked himself with the 30V DC), but he seemed genuinely worried when he was about to drop the thing in the water when he was using AC.
I also like the part where he deliberately glued only a little popsicle stick to the rail as a handle, so that he almost had to dip his fingers in the water.
btw he's clearly following a "no switches" rule in most of his videos
Yet another small correction: water molecules do have a magnetic dipole, too (besides the electric one) and these are, course, randomly oriented.But if you freeze the water under a strong magnetic field you'll get a weak magnet. I wrote another small correction to the light bulbs video (about halogen second glass layer, is not for aspect but for UV-cutting, the first quartz one doesn't), but I suppose is quite unlikely to find them... just in case, give back a signal, doing it just to improve your videos, which I follow.
Is it because of the crystalline lattice of ice?
Just discovered this awesome channel
Mehdi, fantastic work, you could make make paint drying entertaining
The world needs more teachers like you
Salt water electrolysis produces Chlorine gas, hydrogen, oxygen and sodium hydroxide (which gets dissolved instantly) - but in quite inconsistent ammount. Also for the electrolysis to happen, you need around 1.3 Volts, at that voltage you are probably just frying the water, but I would do this outside just to be sure :)
Wouldn't it make HCl gas instead of Cl gas?
HCl doesn't like to stay in gaseous form, since you are in water Clorine from the salt can form HCl still in liquid form and then get airborne as Cl₂
You also need inert electrodes like lead dioxide, manganese dioxide, cobalt(III) oxide or platinum. Aluminum, copper and even stainless steel will react with chlorine forming chlorides in the solution, which react with sodium hydroxide forming sodium chloride and a precipitate of transition metal hydroxides.
@@mernokallat645 I wanted to use the same kind of electrolysis to produce (Na+,ClO3-) but ended up with a nasty orange mixture due to the electrodes not really made of pure titanium but bad alloy. I suspect the solution contained quite a lot of bad Cr6 ions, which are carcinogenic...

Your having such a good showing this, makes learning alot more fun when you learn from a MAD SCIENTIST.
I love how he can jump between different areas of science so quickly while still being equally educational about all of it and finding ways to shock himself all in one video.
He's clearly been doing this long enough to know how to get his audience engaged
He jumps at every electric shock. Notice carefully
He instinctively knows how to shock himself at this point
He knows what he's doing, and that's why we love his content!
Applied Science is his degree
Honestly my expectations were exceeded! Seeing it spit out the water when it was poured in was actually more than I expected.
5:06 RIP electronic danger noodle 😂
I'm surprised you are still alive.
I am in the field of electrical engineering myself, working for the power distribution company in my country so i do get to watch massive sparks and loud explosions every now and then. Your videos are always a joy to watch. Been following since you were at like 800k subscribers although not really active in comments. This would be my first one. Keep up the great work!
Seeing sparks and explosions in power distribution sounds exciting and also mildly concerning. ... just like Medhi lol. Also nice first comment :P
It's just the energy of mehdi that carries him throughout the video !! Absolutely love it 👍
The true perpetual motion machine.
Energy......
Some energy carries through Mehdi at 12:38 too.
the dude involuntarily jump starts himself every video... n wonder he has energy...
This channel is perfect for learning and having a good laugh good job man
1:28 It is...just a little bit.
Even with strong magnet they move slowly
3:03 still catches me off guard it's so good, you expect the shock to happen when he puts them inside the water not after the experiment has been done
I jumped when I first watched it 😂

I freaked 😂
I love how mehdi says he hates being salty, while he is almost always salty already

Thank you Mehdi. I was having a stress induced stomachache and panic attack from studying, but it helped a bit to watch this video of a man shocking himself for science.
Breathe deeply and slowly. You can do it 🙂
Good luck on your studies! May the cramps kindly fuck off
Literally same here
I actually did a extended essay on magnetohydrodynamic drive and it is a propulsion device for ships (and a full scale ship has been made with it before). But of course it only works in salt water. Had a really hard time with weak school lab power supplies and lousy magnets to get readings haha
I just had what I thought was a great new idea to use it on a submarine or boat, but I guess not. Also, wouldn't a boat using that create chlorine, harming the ecosystem
@@josephzamora2267 I'm pretty sure the gas thats coming off saltwater is a stoichiometric mix of hydrogen and oxygen. If you could channel the gas from anode and cathode into separate tubes and mix them at the end and light it off you could use this for additional thrust. HHO is pretty violent, so it'd probably be difficult to manage, but I'd pay to see it at boat scale. If you were to make this at boat scale and drop it in the ocean you'd need a hell of a lot of voltage. Also the cathode will eventually corrode away, leaving you stranded.
If I'm not mistaken, magnetohydrodynamic turbine also quite complex - it's rather a coil gun than a railgun?
@@noalear Nope, if it's regular salt then what's comming off is hydrogen and chlorine. They are also energetic, much more so than regular HHO, but that mixture can combust when exposed to strong light even and is also poisonous.

And they are. He is using table salt - natrium cloride. The cloride part becomes a poisonus gas....
You can feel it way before it becomes dangerous.

13:31 yeah actually at high salt concentrations there's enough chlorine anion that it overtakes oxygen production so you get pure chlorine gas and hydrogen gas, as well as sodium hydroxide in the water. Concentration is probably way too small to cause harm here but it's an industrial process to produce hydroxide and chlroine iirc (chloralkai or smth)
@ 13:35 EB just revealed the caterpillar drive technology
Very great ! Keep on with this !
Pure water isn't conductive but being a polar molecule is affected by magnetic fields. That's why the AC moves water but DC doesn't, DC doesn't make a moving magnetic field. If you hold a staticly charged balloon by a running faucet, it will pull the stream towards it since the slightly charged end of the molecule is moving past the static magnetic field from the charged balloon.

"I don't know whether these gasses are poisonous or not"
Does nothing to prevent him from breathing them.
True engineer
Knowing that water molecules are split into hydrogen and oxygen by the electric current takes away a lot of fear of poisoning (and brings up other ideas which are involving playing with fire). Only danger present is the salt which can produce some small amount of chlorine gas. Shouldn't be much of a problem if you don't run this experiment for hours and stick your nose close to the gas bubbles.
@@DonkenAndToivolaRR Chlorine will form more easily than oxygen but you can smell it before the amount reaches poisonous levels.
@@DonkenAndToivolaRR yeah, you can't die or have irreversible injuries from slow chlorine buildup. You will run away crying long before it reaches dangerous concentration. The only situation where you can get seriously injured or die from chlorine is when you're instantly exposed to high concentration of it and you have nowhere to run. Then you'll cough your lungs out. Literally.

I work as an electrician and I attempt to graduate as an electrician engineer here in Argentina. So thank you so much 🤝
13:28 These "gases" are probably hydrogen and oxygen xD
It's salt so it's hydrogen and chlorine
Oxygen isn’t broken off in this reaction, but it is releasing chlorine which is poisonous.
due to the salt ist actually chlorine and oxygen
Thanks for a great video as usual! This doesn't need a fancy name - it's a simple example of the right-hand rule (the Lorentz force F= qv x B associated with a charge moving in a magnetic field producing a force as the cross product of those 2 vectors). As -ve ions move towards the +ve plate they will experience a force along the channel. The +ve ions move in the other direction across the channel, but because they are of opposite sign, the effective current is in the same direction and so they also experience a force in the same direction along the channel and so the entire body of water is pushed along the channel. Yes the gases are poisonous (chlorine if you used table salt) - far safer to use sodium bicarbonate to make it conductive, but when has danger ever stopped you from experimenting! 🙂 A cool thing I created back in high school, along the lines of what was shown in the debunked video, was to make the water spin - put the water in a petri dish and line the interior wall with foil, place a magnet under the dish and another with the opposite pole above the dish, suspend a pin from the top magnet that dips into the the center of the water, run a radial current from the foil to the pin (via a connection to the top magnet) and viola, you've got a model cyclotron. 🙂 Cheers.
Yeah fancy names are just historical. Railgun - the simplest and earliest example of Lorentz force use by someone who tried to conceive an electricity-powered gun. Originally it's what engineers call "linear motor" and concept of railgun was introduced in 1910s. Gauss gun or coil gun - uses same rule but force is created by inducted currents. This "water railgun" was originally conceived in early 80s and quickly replaced by "water coilgun" - a.k.a. electrohydrodynamic turbine.
I am learning about the right hand rule in college right now and was wondering if you could explain it to me, I know your thumb faces the same direction as the current but what does your pointer and middle finger represent and how do you know what direction they go in?
@@bluefates58 Plenty of videos online covering this. Most use 2 fingers and your thumb but I prefer using the fingers of the hand to represent the magnetic field lines and their direction and the palm or bent 2nd finger to indicate the push - e.g. ua-cam.com/video/47uESIjJSTg/v-deo.html - be careful with exams as they almost always give problems that make it easy to use your left hand by mistake.

thanks for the video, you are one of my favorite youtubers. there is so much idiotic stuff on youtube it makes my head spin, but watching your videos is like fun therapy for me
As I understand it one of the major problems with the rail guns in military development is the arcing that happens at the end of the barrel when the projectile is breaking contact. I think I saw a little of that effect going on in the water railgun!
