What a fun demonstration! Show the video, or better yet, have your physics learners construct this hex nut pendulum and test it themselves. Then have them discuss in groups why the single hex nut wraps around the finger. See if they can figure out that because the pivot length is decreasing and the velocity is increasing so rapidly, the pendulum makes full circle swings due to increased amplitude!
