Great demonstration of harmonic motion and Newtons 3rd law.
Whoa what the fuck that's cool.
I love how the table's movement reflected the synchronization.

The table is slowly bumped in the opposite direction of the motion of all the metronome pendulums.
Over time, the conflicting force vectors will cancel, slowly equalizing the force exerted by each metronome.
SCIENCE!
[quote]As each metronome comes to a stop & reverses direction at the top of it’s swing, it transfers energy to the platform. This energy transfers through the platform to each of the other metronomes.
The energy transferred to the platform from each metronome starts out of sync, but the waveforms of the energy interfere with each other, and at the location of each metronome you end up with negative or positive waveforms which in turn have an effect on the interference pattern. This keeps going until there is a balance – this balance is only achieved when all of the metronomes are in sync. The interference pattern is now a standing wave, which keeps the metronomes locked in phase.
When the whole contraption is put on the table, the table absorbs all the energy, reducing the interference patterns. You can see this phenomenon in many different types of oscillating systems, which can cause some major problems, especially with traffic on bridges and wind around buildings. You could also do the same thing with ticking watches, or even watches, which will eventually tick in time if places on a thin sheet of cardboard help up something like the cans in this video.
Of course if you’re a synth fan, you know that waves like these have harmonics, and the synchronization will also work with multiples of the fundamental frequency. You could presumably set some metronomes to half-speed to double-speed, and they would all tick in time, with different rhythms.
In cathode ray tubes (ie old TVs) this concept was used to lock the vertical and horizontal hold to keep the picture from “rolling”.[/quote]

Take the 'd' out of your name!
The one in the right corner that synched in the opposite direction at first, what a jerk
Wow I didn't even realize the platform they put it on. I just thought it was a 4 legged table.
Damn conformists...
Jokes aside, that's pretty awesome. I love physics!
there's something beautiful about the sound when they all begin to converge into one synchronous beat.
What the fuck how does this even work
Fucking magic
Sounds like soldiers marching. Amazing how the momentum transfers from the platform to every metronome.
I see, it's all about equilibrium... The surface they're sitting on is free-moving, and it reacts to the metronomes. The surface moves according to the average force of every metronome in whatever direction. The movement of the surface, in turn, influences the motion of the metronomes and it all feeds into itself until the metronomes are all synced-up. Blows your fucking mind...
Reminds me of this song:
