NASA let me test my weird chain theory in space by Steve Mould: YouTube (main video), YouTube (full video call), YouTube (extra experiments) #microgravity

a GIF of astronaut Don Pettit on the International Space Station; there is a loop of chain floating in front of him, and it's rotating and individual segments are following the course of the loop, with the subtle bends in the loop staying stationary; this is stays stable as Don Pettit talks to us through the loop and points things out; friction is causing the loop to slowly become more round, more evident when he tries this with the larger chain at his side

I know him from his Saturday Morning Science series. I posted one of those experiments years ago, but nobody here liked it. Maybe I should repost it as a GIF.
