Scientifics Direct Rattleback Space Pet, Colors May Vary

Description

Spin It One Way, Then It Reverses Direction On Its Own! After being spun, and just prior to reversing direction, a Space Pet rocks up and down on its long axis. Space Pets have a counterclockwise spin bias, resulting from the shape of their smooth ellipsoidal base and the distribution of mass with respect to the axis of spin. Colors randomly assorted.
