Newton's cradle consists of five identical balls, each one hanging on a frame by two threads of the same length, all of them being aligned and in contact. When you pull out the last ball on the left or on the right side and let it go and bump into the other balls, you will see that the ball of the opposite side will move out and reach the same height of the first ball. However, the rest of the balls will remain motionless. Newton's Cradle was invented in 1967 by English actor Simon Prebble and named after scientist and mathematician Isaac Newton. It shows one of Newton's Laws; energy cannot be destroyed or created, only changed. The result is different depending on the number of balls you use each time. It is an endlessly amusing, rhythmical effect and a great gadget on your desk!
