Yeah, the up-loop is gravity, and the vibrations in that loop are caused by varying friction in the chain as it is pulled out of the pot, shaped by the very specific form of the chain (each link doesn't permit a very large angle of bend (120 degrees or so?).
Part of the wave is from the structure that's in the pot.
To the extent that it tugs and pulls, yes. But the overall structure of the wave is remarkably consistent.

I'm not sure how much play we see in the chain, so it could be more, but, yeah.
Very cool. But how did he discover this phenomenon? I mean, who has 50 meters of beaded chain laying around to play with?
+David Newman psh, someone doesnt know how to have fun on a saturday night! 🙂
