A slow zoom through the center of beautiful snowflakes. The shape of every snowflake displays its utmost internal organization. The repeating molecular arrangement of ice classifies it as a Mineral. Billions of identical water molecules combine to form a single snowflake. Its hexagonal symmetry begins at the molecular level, 10 million times smaller than the self-organized product. This mirrored symmetry has to do with the structure of the water molecule itself. H20. Oxygen is heavier than Hydrogen, which makes water molecules join together the same way every time, building hexagons out of every six individual molecules.
