in a very messy office, a mesh-backed office chair spins in front of a tower fan. This is a simulated looped video, but in reality the chair seemed to spin forever There is a plastic box filled with heavy components sitting on the chair, and it seems to be the key to keeping the chair spinning. With not box, the chair slows and stops. With an identical (but empty) box, the chair also stops

Okay, a weird thing I can't explain: my office chair - sitting in front of a tower fan - seems to want to spin forever, driven by the breeze from the fan.
It only keeps spinning, however, if a box that's fairly heavy is sitting on the chair. With no box, or an identical empty box, the chair stops spinning very quickly.
I have no idea why it does this. I have videos of the control experiments, and it's repeatable
