Question:
A friend and I are doing a science experiment on anti-gravity. We are trying to build a small anti-gravity machine for class. I have read that it can be done using electro magnitism or using supercondctor. Is this true? Where can we find instructions on how to build it?

Replies:
It really is not "anti-gravity" but "levitation". A doughnut shaped magnet is placed on a rod so that the "north pole" is pointing down. At the base of the rod is another magnet, which can be a superconducting magnet, arranged so that its "north pole" is pointing up. The two magnets repel so that the magnetic and gravitational forces are equal and the doughnut shaped magnet "floats".

I believe Edmunds Scientifics has a kit for this experiment.
