Breaking it Down with Brittney

GRAUPEL: Have you ever wondered, what it is? How tiny balls of snow could be falling from the sky in the middle of summer? It may look like small hail, but it's soft and crushable, which confuses many.

She breaks down the science, how supercooled droplets attach and rime to a snowflake, to form these tiny pellets.
