That's how it goes when you're asking for comments. :-)

It would, eventually, but the velocity of the particles and the heightfield
on which they move isn't exactly the kind of terrain which forms puddles.
That aside, the particles don't use cohesion forces and thus wouldn't form
puddles or stick together like actual water-droplets would. But that'd be
over the top for a simple example anyway.

It's all practice and experience. Once you've became accustomed with some
different animation techniques and formulae for
animation/simulation/calculation, it just moves on from there.

simple examples have a way of becoming large oaks

could you change the characteristics of the water particle on the fly, 
once below say 0.25 height of stone ?

very large :-) for next bit

get your kids to play with a hose and an up turned bucket on your lawn 
and observe.

pick a sunny day
(not for about 3 months in uk, apart from which no lawn, no kids :-)
