A snowflake, as we commonly think of it, is a hexagonal ice crystal. It typically has six sides or arms, and this hexagonal shape is a result of the way water molecules arrange themselves in a hexagonal lattice structure as they freeze. Each arm of the snowflake is a unique and intricate pattern of ice crystals, giving snowflakes their characteristic beauty. While the idea of no two snowflakes being exactly alike is a popular notion, it is a challenging claim to scientifically verify due to the incredible diversity and complexity of snowflake structures.
