NOT ALL SNOWFLAKES ARE UNIQUE.
When water freezes, the H2O molecules join together in hexagonal shapes. The most intricate snowflakes are dendrite flakes, with six points and many detailed arms. There are more ways to grow a snowflake than there are atoms in the universe, so odds are good that no two dendrite flakes are alike. Depending on the temperature and humidity, though, snowflakes may take the shape of simple needles or hexagons -- these are not unique!
