Superconductivity - Part 1 of 3
A 1-2-3 yttrium barium copper oxide superconducting pellet is cooled in liquid nitrogen and placed on an inverted foam cup. When a magnet is placed above the pellet, it is levitated by the superconductor.

Superconductivity - Part 2 of 3
At higher temperatures, a magnet is shown to rest on top of the superconducting pellet. Once the pellet is cooled sufficiently, the magnet levitates above the pellet.
Superconductivity - Part 3 of 3
A magnet floating above a superconducting pellet is spun in order to show the dynamic response of the magnetic field expulsion.
