Pendulum Waves

You’ve already seen the way a no-flinch pendulum works, so now we are changing it up. This contraption is host to many pendulums next to each other but not touching. When you raise them up and let them go all at once, you can see something truly mesmerizing.

They will all start to fall at the same rate, thanks to the laws of gravity, but after the first swing the will not be synchronized. This is due to them being uncoupled, or not connected, and to the length of each individual pendulum. The pendulum furthest away has the shortest length and the closest pendulum has the longest. All of the pendulums in the middle gradually become longer as they get closer.
The period of a pendulum is mostly dependent on its length. Since the lengths gradually increase, so will the periods, causing them to become out of sync. However, that can cause some pretty visually pleasing effects!

Of course, given enough time, all of our pendulums will eventually line back up again in the end. But not before going through some other awesome patterns, as well as what may look like chaos.

This is not the easiest DIY project, but it is possible to recreate, so give it a try. Or you can always find it online or in store, but either way it is definitely worth seeing in person. Let us know what you think!
