This looks like a piece of (black) carbon of a non magnetic material
that is place in a ceramic type dish with liquid nitrogen poured around it. A magnet is then approached to the object.
Watch closely as the temperature changes something remarkably happens!

How it works
Ceramic, when cooled below -186C, becomes a superconductor. Superconductors exclude approaching magnetic fields. In this vid, this process is demonstrated by cooling a ceramic block with liquid nitrogen until it becomes superconductive and then "floating" a magnet above it.

You can get a complete kit to try this yourself at home from various science supply stores.

  i know what to do with that left over nitrogen at work after i freeze fit bushings. by the way, it will "burn" your skin on contact, so its best to wear thick rubber gloves

- Generalk term Super conductor
  Do you know what the (Sc) superconductor is made of in this case?

Bara-Magnetic Material
Beta materials relate thermal effect to electromagnetic effect
cooling using DRY ICE - CO2 = = -32C

I can explain how you copied it!
And then put it on here again!
It's been on here a dozen times in the last couple of years!

great shot thanks!
Too bad this can't work like anti gravity or some thing like that !!
