Consider the following simple “game”: A ball bearing will be rolled down a tube and into a funnel; it will swirl around in the funnel for a while and then roll out onto a table. The goal is to maximize the amount of time the ball bearing takes to roll down the tube and out of the funnel. You may adjust the height of the funnel and the angle of the tube as you attempt to maximize time.
