THE TYPICAL EXPLANATION. “Water (or water vapour) molecules attach to a dust particle and form the beginnings of a snowflake. These molecules crystallize to a hexagonal plate form, every snowflake is formed around this shape. Every one will have repeated hexagon design but each snowflake will be slightly different. A hexagon is a 2D shape with six sides.”
