From a distance, snowflakes may all look the same, but they are not.
In fact, there are lots of different shapes of snowflakes — not just those classic shapes you might try to replicate with paper cut-outs.
In this episode, Dr. Ken Libbrecht answers all of our snowflake questions: How are snowflakes made? Why are they different shapes? How is it that they’re all unique? And how does a scientist who lives in southern California study snow? And, he also lets us in on his brush with a couple Arendelle princesses.
If you’re looking for some fun snowflake activities to do at home, Ken’s provided this great list — and you don’t need to live in a cold climate for all of them.
