This was a very creative way to demonstrate electrolysis, induction, and various other physics and chemistry topics. Thanks for continuing to find ways to inspire creativity in science!
Ummm honestly on RU-vid it’s hard to find a good balance of easy to understand and good information, this is really simple and frankly pretty dumb. If you want me to teach you I’ll be glad to.
I’m a physics major at university. While these are very basic concepts, I was commending the ingenuity behind it and how it opens the door for people who are interested in or passionate about science. He provides a blend of simplicity with creativity in his videos that can intrigue someone who is totally new to science or who has been studying it for decades. Thanks for the offer though.
This made me imagine some post-apocalyptic world like Mad Max, where people are using hand-cranked generators to extract hydroxy gas from seawater in order to make bombs or something
Look up an electrolysis chart, next get distilled water and a salt that has an anions and cations less reactive then OH- and H+, now you have a perfect mixture of H2 and O2 for that bomb you wanted (from sea wafted you are probably getting H2 an Cl2) (also a hand crank is not need, all you need is a power source)
But ya see, in mad max there is barley any water and it is set in a depleted sea with no water other than "morning dew", thus they just make gunpowder out of the ingredients to do so in the game, and if there was still seawater it will still be collected all into the strongholds and maybe gastown to let it's residences live, and they will hardly even know what half of this stuff is and magnets are definetly gone thus making it impossible to do any of that
Bro, been watching for years and gotta say outta all scientific channels out there you're my favorite. I always find myself saying "Eff yeah, science!" Everytime I watch a vid. Keep up the knowledge and thank you as well.
I love your approach to basic science. Just the fact that cranking your dynamo unconnected vs shorted and demonstrating that the effort changes is truly profound. 😁👍
You can find that very same knife in the Cuisinart Advantage Color Collection 12-Piece Knife Set on Amazon You know, in case you were wondering.. 🤷🏽♂️
06:50 - So, if the whole circuit was superconducting, there would be no resistance to turning the crank, as no "work" is being done heating up the wire? I think something else may be going on other than "work to heat wires". 🤔 Would it suddenly be free to move if it were all superconducting? EDIT: You could try using a super-cooled magnet sliding down a super-cooled tube to see if this is true. Eddy currents should flow zero resistance with superconductivity. Would be interesting to see the results.
I believe the answer to this is: if all the conductive parts were superconducting, then there'd be no voltage and therefore no electrolysis. Remember V=IR and so if R=0 then V=0 too.
I'm no expert, and I don't know a ton about superconductors, but here's what I understand. The formula V= IR isn't true for superconductors. Think of superconductors as a circuit that allows current to flow without voltage (once current starts flowing it won't stop). Current needs to be flowing before the circuit is a true superconductor, and then it's value will stay constant. I think that the work in the video is proportional to the resistance, so I think that if he set it up right there wouldn't need to be any work done. Someone correct me if I'm wrong.
Actually, comes to think about it, magnets have a harder time moving through superconductors due to flux pinning. But then what if the magnets were super-cooled as well as the superconductor? Hmmm... I've never seen that done before. I know magnets lose their magnetism when they get too hot but no idea whether it enhances the flux pinning effect when super-cooled.
You should totally set that on fire while cranking and just have a manual fire Cuz like with logs and stuff its automatic n stays on fire, but if you stop cranking the fire turns off
Imo its not volume of water, but larger the size of such powerful magnet with more number of copper windings, that will make it harder to crank, inturn producing higher volts of electricity....
Hydrogen: See my Twitter page under the same name as this comment to see just some of what some nations are doing as they implement Hydrogen into their national economies for various reasons. Hydrogen is the most abundant element in this universe.
hydrogen ions don't exist on their own, those are protons and they aren't stable, he means two water molecules react to form OH- and H3O+ (hydroxide and hydronium)
Awesome videos...where I can see the actual physics working..our teachers don't show this to us during school...very interesting videos buddy..thankyou very much..hope I could do that too..
7:00 It is also really really hard to crank because the magnetic field generated in the copper coils by electrons moving around in them is countering the magnetic field of the neodymium magnets. This is Lenz's Law.
You do this experiment each time when you in a shop. One slit is your mouth, and second is a nose. (coronaviruses projectiles are already present in a shop)
This guy makes almost every video, no matter how simple the topic, so fun. I hoped he would light the gas on fire and he did :D This gives me an idea. I'd like to see a video in which he has some sort of installation where hydrogen and oxygen collects in a tiny container which he can set on fire so it would work as a candle which is basically generated by hard work.
Me: speeds up the video Mr science guys voice: *chipmunk* Me: speeds up more Mr science guy: STOP I CANT BREAT WHEN TALKING Me: doesn't care Me from another AU: 私はピークに住んでいます
What's funny is that you wouldn't know by looking at that board that the wires are attached directly to the generator and run along the underside of the board. He makes it look like the generator is magically inducing a field into the wires thru the air, which is indeed possible, but not thru that setup.
The ionized water molecules are 1 in a 10¹⁴ so veeery little, in a reversible reaction. This is caused by the ability of water of being at the same time both an acid and a base but only a few part of it. There's a lot to talk about this incredible propriety.
Think of a way to separate those hydrogen and oxygen into separate container. And also think of a way to rejoin them in order to make a very pure water
This could be a way to desalinate seawater by hand. The seawater already has salt. Which I assume will slowly turn into sodium hydroxide as the chlorine is released. You can collect the hydroxy gas and burn it into a device to recollect the water vapour and boom you have fresh water.
