The small cylinder is (possible) made of silicon. Can not identify the black block (possible made of carbon). If the cooling agent is liquid nitrogen (LN2), the temperature of the block will be at around -320.5 F degrees. As far as I know, silicon will acquire magnetic properties at superconductivity temperatures (around 2.5 Kelvin degrees). If, in this experiment, the cylinder is made of silicon, then the cooling agent could be liquid helium. What do you think about this? Enjoy, watching it!

The shiny disc is an ordinary fridge magnet (looks as if it's chrome plated though). The video illustrates several different important aspects of superconductivity. The way the magnet can be used to pick up the YBCO, and the way the magnet is stable in leveitation (rather than just sliding away) require some care in explanation. The ususal induced mirror" idea won't work. Note also that as the block warms up from 77K the magnet settles onto it as the s/c disappears.

It is most certainly liquid nitrogen. The black cuboid is probably a high-Tc superconductor like YBa2Cu3O7-delta (short YBCO) and the cylinder simply a magnet.
