Caption: False-colour scanning electron micrograph of a collection of ice crystals. Snow & ice crystals have a characteristic hexagonal symmetry. Each crystal is made up from water molecules, arranged with 2 hydrogen atoms making an angle of 105 degrees with 1 oxygen atom. The fixed shape of the water molecule means they can assume a stable crystal arrangement only when arranged as a 6- branched figure. Despite essential hexagonal similarity no two crystals are identical because their growth is influenced by temperature, humidity, air currents etc., & these conditions are never quite the same. Magnification: x600 at 6x6cm size.
