I don't feel like reading the thread, but that's cool.

Its not ice. No where does that video mention that is ice.
Its just glass that has some condensation on it. For example, it was put in the freezer for a bit, then immediately heated.
If it was ice it would crack immediately as soon as that degree of heat was put near it.
Cool, haven't seen this demo before.
Anyone who had an inductive cook top knows that they can put their hand over it and not be burned. Induction only transfers energy under limited circumstances. Metals can be inductively forged and heated because the electrons are moved internally with a current proportional to that applied externally by coils like those seen in the video. Having wasted my time operating a ICP-AES (Inductively Coupled Plasma Atomic Emission Spectrometer) I had tour groups from local high schools come through the lab. Beyond the usual light sable references, I also exclaimed that I could yank open the door to the instrument and thrust my hand inside and not get burned. Mostly because I knew the safety features would shutdown the inductor, but beyond the quartz tube inside which protected the inductor and guided the plasma and did heat up significantly, the plasma itself has very little mass. In the video a small spark provides the free electrons which collide with the water vapor and presumably a inert gas like argon in the case knocking off more electrons and creating the plasma around the ice cube, but only the glowing part is actually being heated, especially if the cube is made of distilled water which has a low conductivity. The light inside the cube is most likely refracted from the formation of plasma in areas obscured by the coil, not inside the ice cube. The flame is from the hydrogen and oxygen split apart by plasma recombining. Hope this helps.
