This will sound just a little daft but why is snow... well snow, and
not ice?
Why is it that a snow flake is a flake rather than a pellet? What is
it that makes the water expand to form a flake rather than just
freezing to be an ice drop?
We were pondering this last night and I suggested the smart bods on
here would know the answer.

I'm sure someone will but drop in on

anyway.

It always amazes me how they say that no two snowflakes are exactly the
same. They obviously have verified this by checking every one that has
fallen from the sky, that would be ludicrous, however, I feel it must be
based on some mathematical theory. This has similarities to a calculation
I did at GCSE Biology which showed why no two people look alike, was to do
with genotypes and chromosomes IIRC.

Anyone have more of an idea than I seem to have !?
