Macrophotograph of a snow crystal showing 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 snowflakes are identical because their growth from cloud,through sky,to the ground is influenced by temperature,humidity,air currents etc. ,& these conditions are never identical for two snowflakes.
