The Gyro-Ring is rally 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. - High performance edition. - Hold the large metal ring in either hand. - Use other hand to spin-up washers. - After the washers begin "spinning", quickly use both hands to smoothly rotate the large metal ring toward you. The washers should continue to spin as long as you rotate the large ring. - For ages 3 and up.
