Floating frogs (with video!)  MAY 14 2009

If you've got a 16 tesla magnetic field, you can levitate a frog.

The levitation trick works because giant magnetic fields slightly distort the orbits of electrons in the frog's atoms. The resulting electric current generates a magnetic field in the opposite direction to that of the magnet. A field of 16 teslas created an attractive force strong enough to make the frog float until it made its escape.

Best part: it doesn't kill the frog. (via afrooz)

Update: Video of the levitating frog:
