Z-shaped Physics Science Accessory Desk Toy Newton's Cradle Steel Balance Balls Attention: Friction and damping effects are inevitable This Retro classic demonstrates Newton's principle that 'action and reaction are equal and opposite'. If one of the steel balls is lifted and allowed to fall back at one end, then one will swing out the same distance at the other end. This causes the beginning of perpetual motion which dies down only as a result of friction, an interesting process to watch. Bring this quirky desk toy and a bit of unprecedented genius into your life for a daily dose of inspiration. The contact of the outer ball with the inner balls of Newton's Cradle has the visually startling effect of moving all the energy through the stationary balls, so that only the outer balls move. It's curious to watch and may well have you mesmerised for hours. But hey! The Newton's cradle wasn't only a tool used by the great brainy man himself to prove a sceintific point, it is also a fantastically relaxing object to have ticking and clicking away at your elbow as you work, rest or play. Have one in your life today and see if you can't steal a bit of sparking intelligence too... Use the law of conservation of energy to produce the interesting product that is made of stainless steel, beautiful appearance simple. Sit back and watct the soothing motion of the steel balls swinging back and forth, listen to the gentle clicking as each ball taps each other - no matter how stressed out you are, Kinetic Balls will have you relaxed in minutes. Package included: 1 Set of Newton's Cradle
