LEGO Multi Pendulum in motion. Simple parts. Surprisingly complex behavior. This build demonstrates a multi-pendulum system made entirely from LEGO, showing chaotic motion, energy transfer, and synchronization effects that are impossible to predict by eye alone. No software. No simulation. Just physics, gravity, and LEGO. Watch closely — every run looks different.
