Rattleback Puzzle - Bulk Pack of 144 (FT)

The rattleback will stop and spin in the opposite direction on its own.

A popular scientific novelty, this is a boat shaped piece of plastic that you spin by flicking one end with your fingertip, so it spins clockwise. Then it stops, and spins back on its own, counterclockwise, in a most intriguing way. It will keep you amazed and amused, and even educate you in Newtonian Physics when you learn how and why it works! These make an extremely affordable giveaway.

Supplied in bulk pack of 144 pieces with instructions.
