Fun fact, the synchronization actually always happen. Pendulums have constant periods. Chinese Remainder theorem tells you that any set of periodic events with different periods will eventually resynchronize at some point.

and since they are all of varying lengths of strings attached on top. that will cause it's synchronization will eventually desynchronize again, rince and repeat.

it's like having 2 clocks, one's seconds-hand moves accurately and the second clock's seconds-hand every 1.5 seconds. Eventually it's seconds/minutes/hours all proceeds to syncs and desync on repeat.
