Newton's Cradle is the physics toy with several balls hanging from string in contact with one another. Raise a ball up on one end and after it taps the others a single ball flies off the far end while the first ball comes to rest. There's a cat playing with one on our class website who can teach you the answer to this question. Consider one that has five balls initially at rest. What happens if you raise two balls together off the left side, and then Let go so together they hit the stack of remaining three stationary balls? One comes up on the right, leaving four at rest in the center. Two balls come up on the right, leaving three at rest in the center. They meet and stop. Three come up on the right, leaving two at rest in the center.

Newton cradle experiment explains the conservation of momentum.
When two balls together off the left side raised, and then Let go so together they hit the stack of remaining three stationary balls, these two balls comes to rest and the far end two balls flies away.
