Amazing! How to synchronize 5 metronomes?

Synchronisation of 5 coupled metronomes done in Lancaster University, Physics Dep, Nonlinear dynamics and medical physics group. Watch the video carefully and try to understand the science behind it.

And the explanation. Here you go: metronomes (or "pendula") when on table, oscillate with random phases, since that is how they started and they are "uncoupled" (no energy/information flows from one to other so they do not "know" each other.) When they are all together on the cans, notice that the cans themselves oscillate little, providing coupling/information crossover. which forces "synchronization" in periodic systems (discovered by Huygens in 17th century).
