What is a snow fluke?

As an AI language model, I cannot find any reliable information on a "snow fluke". However, I assume it's a typo and you meant "snowflake." A snowflake is a single ice crystal that falls through the Earth's atmosphere. Each snowflake is unique and has a complex hexagonal shape, ranging from simple prisms to more elaborate dendrites. Snowflakes develop through a process of supercooling, in which water molecules freeze instantly when they attach to a particle of dust or impurity in the air. Snowflakes can form in a variety of shapes and sizes depending on temperature, humidity, and other atmospheric conditions.
