How It Works

Are no two snowflakes alike?

This is true to a degree, as it rests on the definition of ‘snowflake’. Large, traditional flakes – like that are replicated by humans in winter – are indeed always different from each other, with staggeringly complex constructions. However, the snow crystals from which the flakes are constructed – only visible under an extremely powerful optical microscope – resemble hexagonal prisms. While there is variety, it is incredibly limited, easily allowing a person to spot two that are identical.
