copper pipe

I don't know about you, but magnets have always intrigued me. Ever since I was in second grade and the teacher gave us a box of magnets to do science experiments with, I was fascinated. Here is an very cool video of an experiment with a copper pipe and a magnet. He drops the magnet down the copper pipe, and you expect the magnet to hit the ground. But, it actually "floats" down the pipe.
