This most amazing toy uses a few loose steel nuts placed in a steel wire ring. Give the nuts a spin and then keep rotating the ring. Surprisingly, the nuts will keep spinning as long as you keep rotating the ring. http://www.arvindguptatoys.com/toys/s... This work was supported by IUCAA and Tata Trust.
