I'll hover over it for 18 years.:b

I too was thinking of something else.

I prefer to witness the conception.

OK, I get why the crystals are six-sided (btw, non-io9 link here), but why do they seem to be roughly symmetrical? And I don't just mean "why are the six branches equidistant from their neighbors?", I mean "why do the branches then seem to sport new branches, or fan out like a paddle, at roughly the same locations and roughly to the same degree?"

Like, why does crystal A (above) end in wedges on all six ends rather than, say, have spokes 2 and 5 end in spears like crystal B? Is it just a matter of moisture content and, given equal moisture, temperature, and time to grow, they'd all assume roughly similar shapes?

/or yes. I've never been sure of how to answer questions phrased in the negative.

I think you answered your own question correctly with a question. Is there a grammatical name for that?

The hexagonal shape comes from the structure of the water molecule.

The six points forming coincidentally comes from the environmental conditions being the same over the entire snowflake.
