Description: The Rattleback is a long and thin half-elliptical shape formed in plastic so that it has a slightly offset center of gravity. This offset gravity causes the Rattle back to spin in directional rotation of choice, usually counterclockwise. If you attempt to spin the Rattleback in the clockwise direction, strong preference will cause the Rattleback to "rattle" back and forth after few rotations, stopping and then reversing the rotation back to the preferred counterclockwise direction. The directional preference is so strong that if the Rattleback is at a standstill and you push down on one end it will begin turning. Color may vary. Comes with Teacher's Guide. Assorted colors Includes Teacher's Guide Each one measures approximately 98mm or just under 4 inches. Pack of 10
