 Suppose a metal ball bounces on a conductive plate, bouncing a little lower each time until it comes to a rest on the plate. Suppose the bounces follow the same geometric pattern as before. Namely, the ball is in the air for 1 minute after the first bounce, ½ minute after the second bounce, ¼ minute after the third, ⅛ minute after the fourth, and so on. Then the entire infinite sequence of bounces is a supertask.
