Chilling out with snow

There are many different types of snow. From the fluffy to the slushy, this slippery frozen stuff comes in all different shapes and sizes.  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?
