This is incredibly cool and it makes me sad that I’ve never seen this experiment done in a science museum, physics instructional lab, or anywhere else.
My freshman physics professor showed us a video of a Cavendish experiment, but doing it live is problematic. You need a fairly controlled environment to pull it off because any air currents in the room will push the small weights around, and it also it takes a long time for the weights to move.
