This is the primary platform. A 12V motor mounted on a block of wood with a strong magnet mounted under a board. The Riostat provides variable rpms.

This is the basic spinner. Just a magnet and two strips of beer can hot glued as wings.

The Video is cool

Other things spin too. Here are 3BBs on the platform. The bottom picture was taken with a "Sports" setting on my camera.



Another run of the same aparatus.


Here is a spinning mag with bbs added.
