Have You Ever Wondered?

…………….what a snowflake is? Kimmy is curious so she starts looking up information on snowflakes.

‘What is a snowflake anyway?

Conditions in the clouds need to be just right for flakes to form. Temperatures must be lower than about -10 degrees Celsius at the same time as the air is saturated with gaseous evaporated water (called water vapour). This causes ice crystals to form around tiny objects such as particles of clay or salt. Initially they are too light to fall and only begin their descent when they grow big enough. That descent happens when super-cooled water droplets evaporate and then the water vapour condenses onto the surface of the ice crystal. That makes them bigger - as well as heavier - and now they can fall to earth as a flake. A lot happens to a snowflake's shape between the sky and the ground. ‘ (Source) 

Frozen! The movie? Elsa? Kimmy has to watch this video! 

Meet the Scientist Behind "Frozen's" Snowflakes

You may not know Dr. Kenneth Libbrecht by name, but if you've seen "Frozen," you know his work. He's a snowflake scientist (unofficial title) at Caltech and served as an ice crystal consultant for that "Let it Go" movie.
