With a quick thrust of your hand, the five brass discs spin like tops, displaying the gyroscopic effect. When you turn the ring, the precession or wobbling of the spinning discs creates a contact point where friction transfers energy directly to the discs, keeping them spinning indefinitely! The faster you turn the ring, the faster the discs spin.
The Gyro Ring consists of five brass discs on a 9.5"in diameter ring.
