Here is a satisfying video of exactly 32 metronomes united in synchronous play with no help from human hands. However, how is this possible?
Metronomes are fascinating devices that have puzzled scientists ever since their invention. When metronomes are set off on a moving surface, they appear to synchronize with each other, although there is no real communication between them. This spontaneous synchronization is thought to be linked to physics and chaos theory, though the exact mechanics behind the phenomenon remain obscure. It has been suggested that metronomes may be able to synchronize because of their resonant frequencies and rate of energy exchange between metronomes; however, the specific dynamics of metronome synchronization remain an intriguing mystery.
