Metronomes put on a movable surface free to oscillate will synchronize to eachother.
The phenomenon of spontaneous synchronization, particularly within the framework of the Kuramoto model (all-to-all connectivity), has been a subject of intense research over the years. The model comprises oscillators with distributed natural frequencies interacting through a mean-field coupling, and serves as a paradigm to study synchronization.
Interesting to read. Satisfying to watch.. and experience.
