From the "new to me" file comes this hypnotic clip of 32 metronomes on a wobbly table. They start swinging at different times, clacking away in a formless cacophony. But every swing of each metronome moves the tabletop, which in turn affects their motion, until the feedback loops brings all 32 metronomes into perfect synchronicity. And that's your Friday morning science lesson.
Watch Watch This First first, every weekday morning. Because the best way to start the day is to start it a few minutes later.
