Newton’s cradle or balance balls is one of the oldest, most interesting physics toys that demonstrate the laws of conservation of energy and momentum (and much more). You just raise one, two or three balls on one end, let them go and watch what happens on the other side. Great for physics demonstrations of conservation of momentum or as a desk toy/stress reducer, and makes a great gift.
This is the best quality Newton's cradle available on the market! It has a stylish black solid wood base and high-shine chrome metal posts and 22mm solid metal balls. Great addition to any desk!
Note: This product is not meant for young children. It is a delicate object, meant for use as a desk toy or fun stress reducer. Balls on cradle can get entangled or snap off if not used properly.
Newton's Cradle History
What we call Newton's Cradle today could have been also called Huygens' Cradle or Mariotte's Cradle.
All three physicists seem to have been studying pendulums and collisions in the late 1600 and early 1700. Dutch physicist Christiaan Huygens published (posthumously in 1703) De Motu Corporum ex Percussione (On the Motion of Bodies by Collision) where he discusses his experiments with two pendulum balls of equal mass and the motion being transfered from one ball to another. Around the same time French physicist Abbé Mariotte experiments with 'impacts' - collisions between bodies and comes up with a version of the law later acknowledged by Newton in his Principia. Isaac Newton later comes up with Laws of Motion and gets all the credit.
There is much confusion over the origins of the modern Newton's cradle. Marius J. Morin has been credited as being the first to name and make this popular executive toy. However, in early 1967, an English actor, Simon Prebble, coined the name "Newton's cradle" for the wooden version manufactured by his company, Scientific Demonstrations Ltd. After some initial resistance from retailers, they were first sold by Harrods of London, thus creating the start of an enduring market for executive toys.Also Known As: newton's cradle, newton's balls, swinging balls, balance balls, executive ball clicker, desk balls, swinging wonder balls, newton clicker
