Red-hot Ice Cube by Induction Heating

did not the ice melt

I saw this kind of induction oven before.
It heat metal very rapidly with a high frequency alternative voltage tru the black spiral wire. It heat the metal by electromagnetic current, so no need of contact. In this demonstrator, they puted a peice of metal in the middle of a regular water ice cube. The light come frome the peice of metal in the middle. All the cube become red because it is sursatured of light. In the middle of the video, we can eaven ear the piece of metal falling on the marble!

of an explanation. .

so we heat a rock and get a light.

very innovative.

is that a light?

just a light! it's cant heat to red-hot so quick... and it's not melting

Its a kind of rock used as after shave for its antiseptic features. A small piece of it, if deposited in a bucket of tap water and left for an hour, will make invisible particles deposit at the bottom and you will get crystal clear water.

fake !
