Step 1: All You Need...
A Paperclip and a pair of needle nose pliers. I used the plastic covered paperclips because they are better looking.
Step 2: How to Do It...
Using a regular paper clip, the height b and the radius of the circle c are about 1cm or .4 inch. Bend the angle a to about 50 degrees
The spinner will run well even if the curvature of the circle is not perfect. With a well made top, you will see the circle and the shaft very clearly, while the rapidly revolving spokes will be invisible. When you spin the top with your fingers, it spins very fast, with speeds possible up to several thousand rpm.
The final trick - shown in the video - uses a tiny Neodymium magnet placed on the axis of the top, trying not to mess with the balance. The top will then be attracted to another metallic object, in this case another paper clip bent into a curved shape. The spinning top clings on to the curved shape and spins around its edge.
