Casual Friday — fun and games with superconductors

This year marks the 100th anniversary of the discovery of superconductivity (and I forgot to send a card…) Anyway, courtesy of the ASTC (Association of Science-Technology Centers) is this video demonstrating quantum levitation, a.k.a. the Meissner effect — the ability of a superconductor to float over (or if you prefer, under) a magnet in a variety of fun and interesting ways (direct link):

Like this? There are all sorts of great levitation videos on YouTube (although this is the best I’ve seen). There’s also a really good explanation of the physics behind this demonstration here.
