I discovered that a large ball bearing will spin for a unexpectingly LONG time when placed in a glass bowl. I was able to get one spinning for over 2 minutes. It was so long that I felt I needed to add a few extra clips of other tests to keep people from falling asleep! The watch is there to show that I didn't cheat. - The large bearings measure around 37mm and were removed from a very large extruder during an overhaul. The smallest balls are Pachinko balls.
