In the 80's you'd expect to see a Newton Cradle on the desk of every high flying business executive with style. That and the fact that It was the staple Father's Day gift given to every dad year-on-year!
Every action has an equal and opposite reaction. It's such a familiar mantra
that it doesn't even seem like science any more. Lift one of the hanging ball
bearings at one end, let it drop and watch the one at the opposite end swing
away. Use two ball bearings and two will be displaced. It makes a great talking
point, and it's infinitely classier than a USB humping dog.
Newton's Cradle, named after Sir Isaac Newton, is a device that demonstrates
conservation of momentum and energy. It is also known as an 'executive ball clicker'. Newton's Cradle is one of the classics from the 80s that is making a comeback as a retro desktop stress reliever. A classic executive toy and makes an ideal desktop gadget!
