@Revolutioniz Is plagerism the new War on Drugs? I keep forgeting who to shame these days...

@I-IS-BORED It`s not if you consider a description as representative of the poster. I was totaly fooled! I agree with MildCorma, it`s just showing how only the metal gets hot. Although, as chimmeychang point`s out, they never said the water was pure. Any material will, under the right conditions, conduct electricity.

Dude, Piepig! Way to cool the fire between MildCorma and Revolutionz! (Hee-hee)
On a side note I totally think Revolutionz is some sort of a student cause grammar woah!
Also, thanks for the laugh! ^_^

also, the ice may be suspending metals that aid in conductivity, no one said it was pure distilled water. also also, when salt water is bombarded with the right frequency of radio waves it burns due to the release of hydrogen, or so i read somewhere once. I am not sure if distilled water would do this with just heat generated from an electromagnetic current, but its not too big a leap.

They didn`t even melt it.

@Boredyeti have you ever seen metal catch fire? cause i have, fire is just the release of photons from atoms of the surrounding gas becoming less excited. you can see metal catch fire all of the time, my dad could make metal spark a flame with an arch welder.

@MildCorma you`re a drating tool. i already told you earlier that i didn`t copy wiki, and when i checked the wikipedia page, there were no similarities besides the basic idea i was getting across. and even if i did copy past wikipedia, that would make me right? so stfu and go troll someone else. you dont know wtf you`re talking about. you`re just a child with a keyboard.

@revolutionz

clearly, you are not a physics student if you actually copy paste wikipedia word for word... nice going, especially as your second year should have probably contained some modules on semi conductors and magnetic properties, so copy pasting wikipedia wouldn`t be required. YOU GO INTERNET SCIENCE HERO!

@thedaveman

No mate it`s basically a demonstration of how induction heating works in that it will only heat metal and not non-metallic objects.

So I`m guessing the ice starts to sublimate but I don`t know how it glows. I`m guessing that the magnetic flux running through the ice cube causes the electrons in the water molecule to become excited in an elevated state then emit light when the electrons drop back down to their lower state. Two things are happening. 1. Magnetic flux through the cube and an increase in temperature. I thought that the increase in temperature came from the number of coils. Since there are only a few coils there wasn`t that great of a temperature increase but a great magnetic flux through the cube. I could be wrong, but this is my guess. Do you agree or disagree with this comment? Why or why not. I`ve never really understood the link between induction heaters and their magnetic flux.

For the record - i never said that it was the ice burning. I was just saying that the induction coil, built that way, would have a hard time aiming at something below its area of effectiveness, which in this case, would be below the coil.

Sure, I may be wrong, but my real offense was at DrProfessor calling someone an idiot with almost no provocation.

AGAIN - the metal is very likely INSIDE the ice, INSIDE the coil.

@Revolutioniz If there`s something under the ice, exactly HOW is the induction coil supposed to heat it? it`s kind of inefficient that way isn`t it?

@deviros you`re so wrong, there is a piece of metal centered under/in the ice that heats up and turns red, glowing light is just passing through the ice. hte point of induction heating is using magnetism, and containing hte heat.

why do so many people here spot out bullpoo without actually knowing if they`re right? you`re on the internet, if you`re going to comment about something, it`s not hard to drating search it. instead of misinforming people..

@DrProfessor:

Uh, no, there`s nothing under or behind the ice getting hot. There may be something IN the ice, but the point of induction heating is that the heating element doesn`t get hot, and doesn`t glow.

That`s not the ice getting red hot or catching fire. Those are things under and/or behind the ice getting red hot and emitting flames, which you can see through the ice because IT`S F*CKING CLEAR YOU DOLT.

Idiots. Ice doesnt burn. Water doesnt burn either. It just goes into a gaseous state. What you are seeing is the vapor with an orange color from the coils.

This is impossible. My guess as a simple undergrad student is that there`s a piece of metal hidden behind the ice, which is what gets heated and shines on, and also volatilizes the ice.

Yeah, no. Either there`s something going on similar to an electrolysis process and those flames are the gases recombining or this is some tomfoolery.

@MildCorma i just checked the wikipedia site, there are hardly any similarities besides the fact that they`re both accurate. it doesn`t take a genius to figure out that if i know what im talking about, then wikipedia might same similar things. douche bag.. i`ve been a physics student for the past 3 years, i learn this poo every day

Is that really fire, or is it just steam reflecting the light given off by the ice cube (or, I guess, the metal inside the ice cube)?

It looks more like fog than actual flames...

I could be wrong here, but I don`t think it`s the ice that`s on fire. Yes, the ice is so hot that it`s glowing, but I think the fire is in the air, around the ice.

Still a very cool display though.

Induction heating is basically using any object that can transfer current (in this example, an Ice Cube, or to pre-empt the "omg ice cubes can`t conduct very well!" I`d like to add that specifically the reaction gains pace as the ice melts and water conducts). The object is wrapped in a coil and a current passed through it to cause the effect. This is fairly basic stuff, as the theory behind it is used in motors and electronic coils all over the place.

This is a method of induction heating using the magnets and metal inside the cube of ice. the eddy currents generated only heat the metal and the ice appears red hot. but the appearance is just the light from the red hot metal centered in the ice out of sight. the reason the ice does not melt is because the magnets produce a current that holds the electrons/heat near the metal, so it cannot radiate outwards.

This technique is used in nuclear fusion. they line the inside of a large doughnut shaped machine with strong magnets. when conducting fusion experiments the atoms heat and mix into a plasma reaching upwards of 150million degrees. but the heat is contained through the use of eddy current produced by the magnets and the electric charge.

In case anyone was wondering.

It`s misleading. First comment on YouTube is:

It`s a light source making the ice glow.

If it were hot enough to "burn" the ice, it would just instantly turn to steam. Water cannot burn in any form.
