How To Make A Pendulum Wave (Science Experiment / Physics Toy)


For this project I show how to make make a pendulum wave, an interesting science/physics experiment where a series of pendulums is measured so that each one moves slightly faster than the one before it. If measured correctly the pendulums converge to form a variety of patterns on a repeating cycle.

Here are the measurements I used, starting with the longest pendulum and moving toward the shortest: 230mm, 211mm, 196mm, 183mm, 170mm, 159mm, 149mm, 140mm, 131mm, 124mm, 117mm, 110mm, 105mm, 99mm, 94mm, 89mm

Using the equation in the video you can make a pendulum wave of any size by replacing the variable ‘L’ with the desired length of your longest pendulum when calculating the variable ‘K’. Once K has been determined for that starting length Just replace the variable ‘n’ with the number 2 through however many more pendulums you would like in the series and calculate L for each of them.

I found the equation for calculating pendulum lengths on this page:

A big part of how I’ve been able to keep making videos on YouTube over the last year is thanks to Patreon supporters. If you enjoy these projects please consider contributing on Patreon and you’ll get some other cool stuff like early access to videos. Most of all your support will mean I don’t have to rely on the volatile YouTube ecosystem to keep this channel afloat, and new videos will be assured no matter how bad YouTube messes things up in the future.
