Pendulum Wave

This wave pendulum proves: physics can be extremely beautiful!
  • Pendulum with 15 steel balls
  • Demonstrates basic physical principles of waves
  • Every ball has its own oscillation period, which allows different wave formations to occur
  • Perfect for spreading waves (!) of peace and harmony at home or at work
  • Includes a bar for moving all balls at the same time

Description

  • Pendulum with 15 steel balls
  • Demonstrates basic physical principles of waves
  • Every ball has its own oscillation period, which allows different wave formations to occur
  • Perfect for spreading waves (!) of peace and harmony at home or at work
  • Includes a bar for moving all balls at the same time

First of all, we have to clear up a misunderstanding: this pendulum is not the bigger version of Newton's Cradle. The Pendulum Wave doesn't demonstrate the rules of momentum and energy, but rather the dependence of the oscillation period on the length of the thread.

In short: the longer the thread, the longer the oscillation period. Or: T= 2xPi x root I/mgd. To learn more, check out the Wikipedia entry. ;)

All 15 balls on this pendulum have different thread lengths, which results in every single ball having its own periodic time. This way, they create the optic illusion of a wave, which becomes more and more difficult until it goes back in line again. Just have a look at our video on the left for a first glimpse. :)

All that's left for you to do is to push all the balls at the same time. That's easy with the included pushing bar (Trust us, this is a highly technical term...). Don't throw it away while unwrapping, it's more than just a filler! The bar is made from the same material as the construction itself and fits between the base plates.

The Pendulum Wave is yet another proof that science can be beautiful, not just in the eyes of geeks and nerd. And as an added entertaining bonus, everybody who doesn't know the Pendulum Wave yet will try to push the first ball - just like Newton's Cradle. ;)
