The original GYRO-RING provides hours of fast-paced excitement for all ages! Just hold the 11 inch metal ring and strike the smaller, colored discs. As you rotate the ring, the discs begin spinning faster and faster, like mini-gyroscopes! At first, the challenge is to keep all the discs spinning. Once you can do this, there are several tricks and stunts to master! 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. Recommended for ages 8 and older.
