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 :)
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...

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.

Thank you Mehdi, I have been watching your stuff on and off for almost a decade now. "I think I made a battery" put me into a laughing fit just like I remember your content doing back when I was 15.
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.
Talking about Eddy currents: I worked for an MRI mfg for 25 years, so I know a thing or 3 about magnetism. Some of our machines used permanent magnets. All the tools used near them had to be made of aluminum so there was no "missile" effect. The fun part was trying to manipulate the tools once in the strongest part of the field (between the poles). If you moved the tool slowly, you were ok. as soon as you try to twist it, say with some wrist action, it would fight you like a wrestler. It was fun to play with.
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.
@@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.
Hi! I'm from Brazil! I got a Micro Bit from the BBC London project and I'm learning the basics of electrics and electronics by my own....your Chanel is amazing....thanks a lot for you and Brilliant 🎉🎉🎉
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.
This is totally hilarious. The comedy and presentation have really gone through the roof on this channel since I last watched. Thanks for making me laugh, I was having a bad day until now. Now I'm ready to take the world on again, cheers !
Thanks to you Mehdi, I went to Purdue University to study Electrical Engineering. I just recently completed our introductory general engineering program (which we call FYE, or First Year Engineering) last semester and now that I’m in my desired program, I’m absolutely loving it! It’s so cool to see the things I’ve learned in school correlate with your videos, and vice versa. Thanks for inspiring me, Mehdi!
Purdue sent me a deferral for EA when I applied last year (class of 22) but Cornell accepted me. Go Big Red! nah who am I kidding this place is fucking depressing
@@jz4774 nahhhhh I decided to do CS instead. It won't really matter for me since im planning on getting an MBA after anyway to make more money on the business side of things and cus I dont really see myself coding my entire life.
Just wanna say thank you for actually taking the time to educate us, the viewers, about this stuff and also scratching the itch to see things go mildly wrong. Very brave, truly the hero we need.
I'm not an electrician and I really don't understand many terms you use and even explain but I usually watch through your whole videos like this one. Good job.
Tech Ingredients did a wonderful video explaining this. Also, you should consider getting a foot pedal for turning on some of your projects. Like a momentary switch from a tig welder so you can have your hands free. When you were holding that mot over the saline solution with the cord in the other hand I was really worried about you buddy.
I'm old enough to remember watching Mr. Wizard on TV. You remind me of him (if Mr. Wizard had a grade school education and no understanding of well, basic scientific principals). Thoroughly enjoyed watching your myth busting attempt. Adam and Jamie would be proud (as they both laughed and cried into there alcoholic beverage of choice.
It's people like this that give me hope for the future, yet I get slight anxiety everitime Mehdi releases a new video. Electricity is no toy, but he sure knows what he is doing.
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.
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)
1:27 water actually is magnetic, just not ferromagnetic. Just like everything else (in paramagnetic materials the paramagnetism just dominates but the diamagnetism is still there) it is diamagnetic and there even is this demonstration video with this levitating frog in a high field lab bitter-magnet.
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.
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. Thanks for coming to my I-just-recapped-the-Wikipedia-article TED talk. :) That movie still holds up today, I think.
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!
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. ruclips.net/video/47uESIjJSTg/видео.html - be careful with exams as they almost always give problems that make it easy to use your left hand by mistake.
I love how Mehdi is channeling his inner scientist from victorian England testing with this new incredible thing called "electricity"🤣 I have a fear for electric outlets and messing with any electric appliances due to childhood accident involving my nightlight and a faulty extension cord, but these videos are such a treat! 😁
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 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'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.
10:37 made me jump. My high power subwoofer slammed in my car. Tons of bass! 100 amp of bass, 1000 watts of bass, 10000 smiles. Well, closer to 75 amps really.
7:05 "Aaaand the resistance of the salt water is... like... What? Minus two megaohms?" If I had a resistor with minus two megaohms of resistance I could put it in a low-power circuit to bump it up XD
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
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.
The aluminum demonstration reminds me of the Lorentz effect, and how you can shoot aluminum rings with it by having electric wire wrapped around an inner pipe. (Something you should definitely do a video on, definitely would love to see the Mehdi version of it!)
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.
@@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.
I love how he acts like he doesn't know until the subject he talks about is shown, at which point he explains what happened/ is happening. Very good teacher, especially with the humor to help us stay engaged c:
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.
I made one of these in high school for an independent study project. Using a big lab electromagnet and a car battery to supply tons of current we got a decent flow going. The project was inspired by “The Hunt for Red October.”
Wanting to learn more about it is the first step in overcoming fear, of course I think a lot of people will agree that, a certain amount of fear is always good when working with electricity, you should never get complacent.
2:30 We did that experiment in Electro Engineering college. You actually don't need the ions - even de-ionized water will work. Our experiment, however, had a high voltage source (not that high, though) connected to two graphite bars - the bars creating a channel in the water tank. Then we have an electromagnet perpendicular to the bars and the electric field between them. We used electromagnets because there were no cheap neodymium magnets at the time. How it works: water is electrically polarized because the electrons get attracted by the Oxygen atom. The high voltage AC source caused them to move from one side to the other in the direction of the graphite bars. When the water moves back and forth sideways it ends up moving forward because it interacts with the magnetic field. I did look for a video but could not find. BTW, I remember that we had to use deionized water because of the high voltage source.
Awesome video, jst remember if you do this at home you must ventilate the room or do it outside, when you electrocute salt water it releases Chlorine gas (highly acidic) along with the hydrogen and oxygen, the sodium dissolves.
Cool video, idk why you would want salt water for anything since it's not like you can irrigate a farm with it. I mean unless you want to kill everything.
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
This did make me curious to research the existence of solid state pumps in general since reducing moving parts is a valuable endeavor. Found one that functioned using a stack of rapidly vibrating piezoelectric discs which seemed interesting. Still has moving parts technically but none of the issues that traditional motors have like bearings that wear out. Reminds me of a similar solid state fan for PC cooling that was presented at CES.

Thank you Mehdi, I have been watching your stuff on and off for almost a decade now. "I think I made a battery" put me into a laughing fit just like I remember your content doing back when I was 15.

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

Talking about Eddy currents: I worked for an MRI mfg for 25 years, so I know a thing or 3 about magnetism. Some of our machines used permanent magnets. All the tools used near them had to be made of aluminum so there was no "missile" effect. The fun part was trying to manipulate the tools once in the strongest part of the field (between the poles). If you moved the tool slowly, you were ok. as soon as you try to twist it, say with some wrist action, it would fight you like a wrestler. It was fun to play with.
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.

Hi! I'm from Brazil! I got a Micro Bit from the BBC London project and I'm learning the basics of electrics and electronics by my own....your Chanel is amazing....thanks a lot for you and Brilliant 🎉🎉🎉
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...

"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....
You can feel it way before it becomes dangerous.

Maybe you meant: UNLESS you are...
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)
1:27 water actually is magnetic, just not ferromagnetic. Just like everything else (in paramagnetic materials the paramagnetism just dominates but the diamagnetism is still there) it is diamagnetic and there even is this demonstration video with this levitating frog in a high field lab bitter-magnet.
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.

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!
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. ruclips.net/video/47uESIjJSTg/видео.html - be careful with exams as they almost always give problems that make it easy to use your left hand by mistake.
This video raises my stress levels more than it should
I love a good debunking video, and having a talented science communicator positively recommend other channels is just a bonus
I love how Mehdi is channeling his inner scientist from victorian England testing with this new incredible thing called "electricity"🤣 I have a fear for electric outlets and messing with any electric appliances due to childhood accident involving my nightlight and a faulty extension cord, but these videos are such a treat! 😁

"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.

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 :).
13:40 I think I will have a hard time sleeping tonight...

Make it your lock screen
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.
Just discovered this awesome channel
Mehdi, fantastic work, you could make make paint drying entertaining
The world needs more teachers like you
The aluminum demonstration reminds me of the Lorentz effect, and how you can shoot aluminum rings with it by having electric wire wrapped around an inner pipe.
(Something you should definitely do a video on, definitely would love to see the Mehdi version of it!)
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?
This channel is perfect for learning and having a good laugh good job man
I am so grateful that I learned, early on, to finish my morning coffee before watching one of these very educational videos.

The reaction after you added the FULL BRIDGE RECTIFIER was amazing! Did you just turn salt water into plasma?
No, thats hydrogen burning from waterelectrolysis.
@@maxschmidt9888 oh thanks I did wonder why it went from water moving to bright flames
@@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.
I love how he acts like he doesn't know until the subject he talks about is shown, at which point he explains what happened/ is happening. Very good teacher, especially with the humor to help us stay engaged c:

Hey Mehdi, I just wanted to say thank you for the content over the years. I love watching your videos.
Mehdi your videos are just insane! I am a HS student and your combination of entertainment and education is really good!
2:30 We did that experiment in Electro Engineering college. You actually don't need the ions - even de-ionized water will work. Our experiment, however, had a high voltage source (not that high, though) connected to two graphite bars - the bars creating a channel in the water tank. Then we have an electromagnet perpendicular to the bars and the electric field between them. We used electromagnets because there were no cheap neodymium magnets at the time.
How it works: water is electrically polarized because the electrons get attracted by the Oxygen atom. The high voltage AC source caused them to move from one side to the other in the direction of the graphite bars. When the water moves back and forth sideways it ends up moving forward because it interacts with the magnetic field.
I did look for a video but could not find. BTW, I remember that we had to use deionized water because of the high voltage source.
5:31 LOL THIS GOT ME LAUGHING SO HARD
14:10 🤣🤣🤣
Awesome video, jst remember if you do this at home you must ventilate the room or do it outside, when you electrocute salt water it releases Chlorine gas (highly acidic) along with the hydrogen and oxygen, the sodium dissolves.

Cool video, idk why you would want salt water for anything since it's not like you can irrigate a farm with it. I mean unless you want to kill everything.
12:27 did the water carry a glob of plasma in an arc at the back left?
😮
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
This did make me curious to research the existence of solid state pumps in general since reducing moving parts is a valuable endeavor. Found one that functioned using a stack of rapidly vibrating piezoelectric discs which seemed interesting. Still has moving parts technically but none of the issues that traditional motors have like bearings that wear out. Reminds me of a similar solid state fan for PC cooling that was presented at CES.
