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.

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.

Features:

  • 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
  • Use: physics teaching instrument
  • Material: bracket and base: ABS advanced plastic, sphere: iron
  • Size: 13.5 × 11.5 × 13.5 cm
  • Net weight: 192g
  • Five balls are hanging side by side, they are in contact with each other and their centers are on the same line.

How to use: first pull the ball on the left 15 ~ 20 mm, then release it, and the ball on the right next to it stops after colliding, while the ball on the right swings up, and the swing distance is the same as that on the left. The distance of the ball is roughly the same
