Newtons Cradle Balance Balls
The balance ball is a game of fun! If you pull up one ball and release, you will see only one ball move from that force. If you pull up two balls, two will react. Try it and see for yourself! Every action has an equal and opposite reaction -- science demonstrates this clearly and simply with a touch of amusement.
