» Floating Magnet -

Floating Magnet is way cool! No, really. "It's a superconductor, a material which has no electric resistance (at a certain temperature). Notice that liquid nitrogen is poured into the reservoir. When certain metals and ceramics are cooled to temperatures close to absolute zero (-459 F or -273 C), they have no electrical resistance allowing electrons to flow through them freely - thatÂ’s whatÂ’s necessary to cause the levitation".
