Desktop Pendulum Wave

A pendulum wave is a type of kinetic art that comes from the movement of pendulums with varying lengths. Moving them all simultaneously results in fun wave shapes as well as some groupings that seem to come out of randomness. It is a neat piece of art demonstrating mathematics that cane easily be displayed on a desk. https://en.wikipedia.org/wiki/Pendulum_wave The lengths of each pendulum should be approximately:Pendulum 1: 60 mmPendulum 2: 73 mmPendulum 3: 90 mmPendulum 4: 107 mmPendulum 5: 126 mmPendulum 6: 146 mmPendulum 7: 167 mmPendulum 8: 190 mmPendulum 9: 215 mm As this length can be difficult to measure with a slide caliper, I recommend simply measuring only the first pendulum and then lining the rest up in a straight line when the rack is held up. The model accounts for the extra length on each pendulum, so as long as they are in a line, they should produce the pendulum wave effect. Be sure to use a thread that is extremely lightweight and flexible. Something like fishing wire
