Check out this "cool" video which shows how a snowflake forms as it falls to earth. The video was produced by the American Chemistry Society for educational purposes.

According to the society, snowflakes start with a grain of dust, to which a droplet of water sticks. The droplet then freezes and re-freezes, accumulating layers as it goes. The crystalline structure of the ice gives the flake its six-sided dimension.

The longer the flake lasts in the cloud, the larger and more distinctive it becomes.
