Harvard built a device with a series of fifteen pendulums in a row, each one of them slightly longer than its neighbor.
The pendulums were set into motion and the result was captured on video.
The patterns that appear in this short video are fascinating to watch and to think about.
Prepare to be captivated by this simple device!
