I am fairly sure the calculations are quite correct mathematically.  Just
to clarify, i'm using 33 integration steps per frame with 0.00111 seconds
per step wich should give real time results with 30 fps.

I made another version showing better the lack of surface tension and how
drag in water works, this time without the water movement.  The balls are
only slightly heavier than water.
