A few weeks ago I showed a picture of some metal spheres and teased that they were for an upcoming project. While the project was put on display, I hardly had a chance to get it finished right.
The project is a Wave Pendulum, and it shows off the varying periods of motion of pendula with different length lines, and how they start in unison, disperse to their own motions, and then, at a set point in time, reconvene to be in sync again! Here's a few pictures of our Wave Pendulum in action, though I'll be fixing it up in the next few weeks and do a proper writeup/movie/diagrams for it!
Here's a quick video I made before entertaining a few hundred people with the pendulum at MindShare a while back! Enjoy!
