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

Making an accidental battery is more impressive than an accidental antenna.

That made me laugh out loud too, hahaha. Such a good moment.
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.

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?
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.
@@mernokimuvek 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...

@@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
Mehdi, you are the type of person that 150 years ago would have been leading electrical discoveries. I love your passion.

Honestly my expectations were exceeded! Seeing it spit out the water when it was poured in was actually more than I expected.

I've been thought that those microwave transformers can kill you instantly.
Seeing this man holding that thing with his hands over water is just too much for me. My god.
It's because he removed the other coil. If you left the second coil in that thing it would have about 6,000 volts and will kill instantly.
@@impicklerick8370 I see. He knows his shit after all.
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.
A fan of Clive Cussler and the Oregon Files?
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
6:06; Please don't try this at home if you are a professional and educated engineer that deals with electricity. Also, Mehdi, don't hold the microwave transformer on one hand to test it by plugging it on; otherwise, the plates that open sideways, and it explodes.
Lel
Maybe you meant: UNLESS you are...
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?

"I wonder if all these gases, coming from the water, are poisonous or not!" He says with joy.
And they are. He is using table salt - natrium cloride. The cloride part becomes a poisonus gas....

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.

"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.
You always brighten our day, Mehdi!

Never sure how much is a bit showing you "what NOT to do" and how much is real carelessness.
@@jamesphillips2285exactly.
It's not poisonous, but it is flammable. It's hydrogen and oxygen gases. It's actually electrolysis. Would have been awesome if you put a cigarette lighter to that fizzing water.
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.

@ 13:35 EB just revealed the caterpillar drive technology
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!
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.
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)
I keep thinking of the caterpillar drive in "Search for Red October".
If a nuclear powered sub used huge magnets then the flow of the salt water would cool everything keeping the magnets below their Curie temperature
It'd have to use batteries as a generator would be too loud.
You'd only need a couple of knots to make a totally silent drive worthwhile.
That it's actually a thing in real life, but it's very inefficient.
With superconducting magnets it's feasible though still impractical. Also chlorine bubbles would be well detectable. In theory if strong running magnetic field was generated making kind of induction motor with water as its rotor, it wouldn't have any electrolysis and bubbles of gas. But I'm not sure it's possible. Usually superconducting magnets generate static magnetic field...
@@allmycircuits8850 Chlorine gas production apparently can be controlled with a catalyst from Iridium oxide and Manganese oxide. Wonder if efficiency could be boosted by collecting the hyrdogen gas and feeding it into a fuel cell.
Glad to see there are several commenters here with good taste in movies. :) BTW: It's The _Hunt_ for Red October, just to be pedantic. ;) Released in 1990, it was based on the 1984 novel by Tom Clancy, directed by John McTiernan and starred Sean Connery, Alec Baldwin, Scott Glenn, James Earl Jones, and Sam Neill.

Hey Medhi, you should be a high school science (physics) teacher!
In the previous video when you made the million amp transformer, you made a vintage fire alarm buzzer. I went to a high school that had that as the fire alarm signal.
Isn't he already? I watched him in highschool from time to time and honestly you couldn't do half these things in the public school system
@@LeafBoye If it's a high school with advanced (AP) science courses, then they may hire him!
Hey Mehdi - if you see this. We used to test in the lab the conductivity of liquids. There is a neat process called titrations where you add a liquid to an other one until it changes colour. Well - if you have something that is black like coke, and it changes from black to black... You can not do much. But you can measure the conductivity of the liquid and measure its contents that way. It is called conductometry :D I'd love a video about this at it is really interesting - uses chemistry and electricity. Lovely stuff :D
Oh so it is used for this,I hate it that schools never say the uses of things they teach.
And btw thx for giving knowledge about it :).
Electrolyzing salt water? You're making chlorine gas there, buddy. Hope you didn't breathe too much of it in.
There is a way to make a water cannon that shoots farther and tighter than the spray of other cheap devices . The turbulence must be arrested with vanes, the barrel should be choked like a shot gun to stretch out the water, increasing it's speed and a bubble of compressed air or Co2 gas should be inserted in the stream to advance the speed again and one more very important thing, use a leaf blower to move a column of air around the barrel of your cannon to match the speed of the water so it does not diffuse into a spray. I think you can do it.

@@maxschmidt9888 I'm not at all doubting you but the spontaneous ignition point of hydrogen is 650⁰C or needs a spark. I don't see either of those conditions with this but maybe there's some tiny sparks we can't see on camera?
@@Pastamistic Thats true. After reading your comment I thought maybe the heat of the reaction, but then I remembered the boiling point and all energy above that is used to vaporise the water so the actuall watertemperature only rises to 100°C. But then I thought maybe the watervapor is electrolysed with just the H3O+ and OH- as Ions and then it possibly could reach the temperatures. Also the gasmixture is at a perfect combustion ratio regarding the oxidizer (H2/O2=2/1). But maybe the voltage is too low (Easiest way of flow and U=RI)? Yeah its possibly small arcs.
6:21 behold the most dangerous-looking thing I've ever seen
4:52 It is Aliumagnetic
5:11 get a room you two
7:10 is where we learn from your mistakes. Even the less spectacular ones.
7:11 I think he made a battery
12:44😂😂 guess he’s never stuck a 9 volt to his tongue.
the amount of fuses this guy must go through on a daily basis is insane-
13:02 He just seasoned the water😂
I am so grateful that I learned, early on, to finish my morning coffee before watching one of these very educational videos.
Thanks, Medhi!!
10:50 the reason for your house getting 113 volts is because you are a bit further from your local high voltage transformer, also during peak hours the voltage drops simply because the higher usage
hes meter is showing 160v, 113v would then be the RMS. something is going wrong but i dont know what
*holds microwave transformer with hands*
*plugs it into 240V*
*drops it in water still holding it*
This is more nerve-wracking to watch than freeclimbing
I don't know why, but the floating Mehdi head at 9:29 had me chuckling like a loon.
I thought I had grown resistant to Mehdi's jumpscares but the 3 minute mark one got me good lol
@6:09 lmao that one got yer attention.
i know that this is what he does... but i am convinced that Death is just over his shoulder saying " you have a lot of nerve being alive!"
"YOU HAVE A LOT OF NERVE BEING ALIVE!" Death always speaks in capital letters. Always.
