This is diamagnetic flotation of a 3 mm cubed magnet. The little magnet is touching nothing but air. This new yet simple understanding of diamagnetic materials requires no power of any kind, just a balancing of magnetism and gravity between two bismuth crystals .

It's about 4 inches tall and 5/8 inches in diameter. It's very easy to set up. Just hold it level or put the piece on a semi-level surface. Slip the cube magnet in the notch. Watch it float and spin for hours, days, as long as you want. It will stay floating like that for a lifetime.

What you get: 1. A near identical device as shown in the pictures. 2. 3 spare floater magnets

Technical Details
Production Method HOW DOES IT WORK? Bismuth happens to be the metal with the greatest amout of diamagnatism. That means that it repells north and south poles of magnets equally. It's a very weak push, and we didn't know about it for a long time. The top magnet attracts the small magnet with enough force to lighten it....a little bit The diamagnetic force of the bottom bismuth crystal can then push the little cube off it's surface without pushing it too high into the upper magnets attractive field. That way it achieves balance in a repulsive pocket of stability between a pair of larger attractive fields, magnetism and gravity. I think many men spent hours of their boyhood arranging and realigning magnets to make another float. (I personally wasted months. I also blew a years allowance trying to build a perpetual machine.) Then we reluctantly learned the Ernshaw Principle that explained the futility of our efforts. He proved some things that nobody wanted to hear. Diamagnatism is a property of the force that Ernshaw didn't really explain. Ernshaw didn't teach us about element83. Buy with confidence.

If you aren't thrilled, just send it back within 30 days for a refund. Have any questions? Feel free to write me. My name is Ernie.

Please note, Magnets are dangerous for children or anyone who might eat them. Two of them can connect through internal tissue and pinch the digestive track closed. Combined with a late diagnosis it has even fatal.
