Not just an iconic office or desk toy, Newtons Cradle is actually a physical demonstration of the fundamental laws of physics and mechanics. Designed in 1967 by Englishman Simon Prebble, the cradle contains five balls, all exactly the same size arranged so that they're hanging in a row. Raise the first ball and let it go and its potential energy is converted into kinetic energy which is transferred to ball two upon impact. This energy then passes from balls three to four and then on the five which, in the absence of any further balls, the kinetic energy drives the ball up and away with the same impact as the first ball struck ball two with. This transfer of energy then continues in an elegant display of physics at work showing the conservation of energy, momentum and friction. Pretty awesome stuff, but this Newton's Cradle lights up too! With three light settings; all spheres remain red, all spheres remain blue or spheres flash on impact, this elegant desk toy becomes a mesmerising light show!
