Is it true that all snowflakes are different?

Snowflakes are all different. The reason they're different is because as a snowflake forms, you have water molecules which are in the atmosphere, and they condense out onto other water molecules to start forming this snowflake. As each one forms, a different number of molecules will drop to form on it, different temperatures will cause part of it to melt again, and then refreeze again, and so there's no set pattern for this to happen. So every snowflake is going to be just a total random process of forming. They should be all different.
