This demonstrates Newton's principle that 'action and reaction are equal and opposite'. If one of the steel balls is lifted and allowed to fall back at one end, then one will swing out the same distance at the other end. This causes the beginning of perpetual motion which dies down only as a result of friction, an interesting process to watch. 11cm

Large version of the classic desktop kinetic toy. Pull back one of the metal spheres and then release to make it connect with the others, sending the impact energy through the chain and making the sphere on the other end react with equal force. This educational toy is not only a mesmerising item to watch, but also demonstrates conservation of momentum and energy in a way that's easy to understand.
