Newton's cradle is an executive toy named after Sir Isaac Newton. It demonstrates conservation of momentum and energy. It can also be known as an executive ball clicker, or balance balls.
It was a very popular executive toy throughout the eighties and found on managers desks across the country. Sadly few of those managers actually understood what it was trying to demonstrate and instead just used it to make an annoying clicking sounds through important meetings!
