Lab Out Loud

Thinking of snow? We first talked to Dr. Kenneth Libbrecht in 2006 when the US Postal Service began featuring his photographs of snowflakes on stamps. 16 years later, we wanted to find out what’s changed in snowflake science, so we invited him back to the show. Dr. Libbrecht joins us again to share new discoveries in snowflake science, describe how he became the snowflake expert for the movie Frozen, and discuss some tips on talking your own pictures of snowflakes.
