What is the minimum required? You seem to be saying:
- It cannot work with 1 mass
- It will work with 42 masses
How about something between 1 and 42? What makes you confident about 42 but unsure about 40?

What if I try 2? Do you predict motion of the pipe further than its own length? Does it depend where they are when they start? I don't want the rules changing after I programmed it.

How long does it remain in that state of 20 accelerating, 20 going the other way, and 2 turning? The masses will probably get out of sync pretty quickly because of their different speeds.
