Cool Facts About Snowflakes
Snowflakes and snow crystals are basically the same, a crystal is one tiny bit of ice, snowflakes are many snow crystals stuck together.

Snowflakes shape and symmetry.
The temperature and dampness of the cloud constantly changes, which affects the shape of each snowflake. Although snowflakes can change shape so quickly, the hexagonal symmetry is kept. Snowflakes can be categorized into six main types, plate (flat), column, stars, dendrite, lacy, needle, and capped column. When the temperature is near to freezing point (0 degrees Celsius), snowflakes become much larger and a lot more complex in design. There are 35 main snowflakes that you could recognize from just looking closely at.

No two are ever the same.
It is indeed extremely unlikely that two complex snowflakes will look exactly alike. It’s so extremely unlikely; in fact, that even if you looked at every one ever made you would not find any exact duplicates.

The worlds biggest snowflake.
According to the Guinness World Records, the largest snowflake in the world was 15 inches wide and 8 inches thick. This was recorded on January 28, 1887 by Matt Coleman at Fort Keogh, Montana. He said that the snowflake was “larger than milk pans”.
