Why is it that snowflakes are always perfectly symmetrical and hexagonal?
The underlying crystal structure of water is hexagonal, so it's natural that something made of ice follows this if allowed to grow that way. As for why symmetrical – well, they often aren't perfectly so, but they're very small, so once a seed has formed it's likely that the whole thing will be ex…
The Short Answer
The underlying crystal structure of water is hexagonal, so it's natural that something made of ice follows this if allowed to grow that way. As for why symmetrical – well, they often aren't perfectly so, but they're very small, so once a seed has formed it's likely that the whole thing will be exposed to the same conditions – temperature and humidity in the cloud – so it's reasonable to expect it to grow symmetrical. Also, there are many other shapes of snow which aren't your classical snowflake shape.
