This is one of those useless How To’s that will never be reproduced again. I don’t see who would have 5 metronomes at their disposal and I don’t see why would anyone need to synchronize 5 metronomes. Having said that I do admit that its interesting to see how they are all timed perfectly by gravity. VIDEO->
Now, I have no idea why but those metronomes make me think of the Laughing Twins clip.
