Make an amazing spinner from an old CD. Stick a marble in the CD hole. The top of the marble will form the grip and the lower end will be the pivot. This top will have a low center of gravity and a large moment of inertia. Stick a Newton's Color disc on the CD. On spinning, the seven colors will coalesce and you will see a white color. http://www.arvindguptatoys.com/toys/C... This work was supported by IUCAA and Tata Trust.
