Description
A simple and sensibly priced version of the old favourite where, once set in motion, the metal balls demonstrate the 'action-and-reaction' phenomenon as they attempt perpetual motion.
A fantastic toy for those children who like repeating motion.
Also a fantastic distraction toy
- When one of the steel balls is lifted and allowed to fall back at one end, 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, gravity and other external forces
- An interesting process to watch
