Newton's Cradle - Isaac Newton declared that ‘for every action there is an equal and opposite reaction’ - this toy offers the perfect demonstration of this fundamental law in an eye-catching and mesmerising display. This mini Newton’s Cradle is an exact replica of the original design and is much more than a distracting desk toy; it’s science in motion!

When one sphere at the end is lifted and released, it strikes the stationary spheres; a force is transmitted through the stationary spheres and pushes the last sphere upward.

You've probably seen this contraption before: Five small silver balls hang in a perfectly straight line by thin threads that attach them to two parallel horizontal bars, which are in turn attached to a base. They sit on office desks around the world.

If you pull a ball up and out and then release it, it falls back and collides with the others with a loud click. Then, instead of all four remaining balls swinging out, only the ball on the opposite end jumps forward, leaving its comrades behind, hanging still. That ball slows to a stop and then falls back, and all five are briefly reunited before the first ball is pushed away from the group again.


  • Designed based on Isaac Newton’s original design
  • Release 1 ball and only 1 ball moves, release 2 balls and 2 balls will react etc
  • Available with a chrome frame and stainless steel balls
  • A fun way to demonstrate the laws of motion in action
  • Popular office toy – aids creativity, focus, relaxation
