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.

"There is a piece of metal in the ice cube. At 00:14. you can hear it melt through the bottom and hiss as it hits the water. This is a demonstration of induction's inability to heat anything other than metal."

@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...

@Revoultioniz

Nice mate, straight from the front page of Wikipedia! Not an internet science hero at all, lol

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:

"There is a piece of metal in the ice cube. At 00:14. you can hear it melt through the bottom and hiss as it hits the water. This is a demonstration of induction's inability to heat anything other than metal. ~shayd333"

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.

Can we get an explanation video or something? My mind has been blown.
