In other words: dew can only be made of smallish droplets, not large ones. You completely blew my mind there! I'd never noticed that before. Does the size of a dew drop relate to the size of the particles? i.e. can we estimate the size of water molecules just by looking at the maximum dew drop size?

Wait wait wait. I was talking about the particles in this particular simulation.

Surface tension is _not_ a function of the size of water molecules. In fact you can change it quite easily just by adding a little soap.

D'oh, I was being stupid, thanks.
