From the Ikeguchi Laboratory in their pursuit of studying nonlinear chaotic dynamics, watch as 100 metronomes synchronize to the exact same timing. The key is the surface that the metronomes are on: a hanging platform that both responds to and influences their movement via energy transference.

Though it may be tempting to jump ahead through the videos, it’s worth letting them play while watching and listening to the subtle changes. There are also additional experiments in triangle, cross, and circle configurations. Will they align in the same ways?

Previously from the Ikeguchi Lab: 32 metronomes unite.

Plus, more rhythm, more kinetic energy, and this pendulum wave demo created with bowling balls.
