Yes, off course I'll never complain, this could be obvious for me, but it will take a little time to accept this strange, but not so much, phenomena for you. Awaile, if there's somenting I can say to convince you, just ask.
There's a nice experiment to made with superconductors, it is to place a supercooled plate over a magnethic field. It does levitate till it warms up. This is becouse current is induced on the superconductor counteracting the magnethic field making a magnet itself. When it warm up resistance appears inside the superconductor and dissipating energy in joule's effect let it falls since no more counteracting magnethic effect will persist. If you search the net for superconductors you'll find a lot.
Cheers.
