For you other rabid technophiles out there, Edmund Scientific now
offers a superconducting disc. For $20 you can have a disc (made by
Tektronix) to demonstrate the Meissner effect with the use of a magnet
and some liquid nitrogen (available from a variety of sources including
the corridors of Wean Hall). The small but powerful magnets from headphones
should work well but Edmund sells them too. Page 5 of their latest Annual 
Reference Catalog.

If you're really gung ho you can by some Yttrium oxide, Barium oxide, copper 
oxide and cook your own. I think a recent issue of Nature (or Science) gave
a basic recipe...
