| The
Gyro-Ring® is really just five little tops of unusual design strung
on a metal ring.
Do you remember how tops appear to start "wobbling"
as they slow down? This rotation of the spin axis is called precession
and causes the ring to press on one side of the hole in the spinning
top. The contact point between the ring and the top can be thought
of as a gear that changes the motion of the upward moving ring into
the top's spinning motion. |
