Newton's Cradle - one of the classic games from the 80s that's making a come back as a retro desk top stress reliever!About the CradleThe Newton's Cradle demonstrates pendulum motion and also helps demonstrate the laws of Conservation of Momentum and Energy, but more importantly, is great fun! It works as follows, if you pull one ball back and release it the energy is transmitted through the 3 static balls and the last ball then swings out then back again. If you pull two balls back and release them then the last two balls swing out, etc. Confusingly addictive!
