The behaviour of the pendulum follows from the conservation of momentum and energy only in the case of two pedula. Indeed, if there are r pendula.. An additional condition for the observed outcome is that a shock wave has to propagate dispersionfree through the chain.
Newton's cradle has been a popular desk toy since being invented, named and produced in 1967 by English actor Simon Prebble. At first, a wood cradle version was sold by Harrods of London and later a chrome design was created by the sculptor and future film director Richard Loncraine.
In pedagogic settings, Newton's cradle is sometimes used to present the concept of "action-reaction" (Newton's third law), with the words said to the cadence of the clacking pendulums as they execute a single cycle of swinging and clacking oscillation. This is not a very clear presentation of action-reaction. In fact, for those who have mastered high school physics the conservation laws can be easily derived from Newton's second and third laws.
The largest Newton's cradle in the world was designed by Chris Boden and is owned by The Geek Group in Kalamazoo, Michigan. It is on public display and is used for science and technology demonstrations. It consists of a set of 20 matched Bowling balls each with a weight of 15 pounds (6.8 kilograms). These are suspended from cables from metal trusses in the ceiling. The cables have a length of 20 feet (6.1m) and the balls hang 3 feet (1m) off the floor.

What was the cradle used for in the gold rush?
The cradle separates dirt, clay and gravel from gold. As the miner rocks the cradle, water washers threw the dirt, separating out the gold. Cradling required at least two men to work. The cradle had a grate and a sieve. The dirt and sediment to be sifted through was emptied onto the grate in the cradle. The cradle was rocked quickly back and forth (in the action of a cradle) while water was poured over the sediment to help work it through. The grate stopped coarser stones from going through, while the fine material was sifted out the other end. The gold would be left behind for easy collection.
