Retro Newton’s cradle
Perfect gift for your friends & families
The balls continue in perpetual motion
Put it on your office desk or home desk or shelf
Get your very own Newton's Cradle. When one of the 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 due to the resistance of the air and friction, an interesting process to watch.
