A pendulum wave with 15 billiard balls

ScienceX on Instagram: "🌀✨ The Pendulum Wave… When Physics Turns into a Mesmerizing Art Show! The experiment consists of a row of pendulums, each with a very slightly different length. When they all start moving at the same moment, they swing in perfect harmony at first. Gradually, each pendulum begins to drift out of sync due to its tiny difference in length. But instead of descending into complete chaos… something magical happens: The motions transform into a visible wave flowing smoothly acr
