Rattleback – Plastic Assorted Colors – Pack of 10 with Teacher's Guide
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.
