I was searching for a video regarding 'circular motion' and gravity and stumbled upon this video!
❝Using a wineglass we show the plausibility of transferring an olive to a Martini glass without touching the olive. Here we model the olive first with a ping pong ball (about 4cm in diameter) and then a marble (about 1cm diameter). The experiment performed with an actual olive is left as an exercise.❞
It was pretty cool. Then I discovered another one of their videos which was even better than the one above. Fifteen uncoupled simple pendulums of monotonically increasing lengths dance together to produce visual traveling waves, standing waves, beating, and (seemingly) random motion.
It started off a bit boring but just be patient. The pendulums started moving in awesome directions as if they were being orchestrated. It was almost mesmerizing.... so don't pass out here on me now...
