Rattle Back Puzzle

Product Description

A popular scientific novelty, this is a boat shaped piece of plastic that you can spin by flicking one end with your fingertip, so it spins clockwise. Then it stops, and spins back on its own, anti clockwise, in a most intriguing way.
Not new, but we got a supply of these at an amazing low price – less than what you would pay for one decent cigarette ! And this won’t spoil your health, or go up in smoke – it will keep you amazed and amused, and even educate you in Newtonian Physics when you learn how and why it works !
