SNOW FLAKES
“No two are exactly alike.” Snowflakes form in a cloud, an environment of water vapor. There are varying conditions of humidity and temperatures and air currents and even dirt and dusts particles throughout the cloud. The hexagonal plate that every snowflake starts out as, tumbles through the cloud, attracting more water vapor that adds to each of the 6 arms or perhaps melting a bit before growing again. Since each snowflake encounters slightly different conditions in the cloud, vapor crystallization varies for each one, making it improbable that any two would be identical. Yet each is a masterpiece...
