‘Science Friday’ Explores the Science of Snowflakes With ‘Snowflake Guru’ Kenneth Libbrecht

Weekly public radio call-in show Science Friday celebrated the most wonderful time of the year with a pair of discussions about snowflakes featuring Caltech’s resident “snowflake guru” Kenneth Libbrecht–who quite literally wrote the book on snowflakes. Libbrecht discusses the geometrical patterns of the ice crystals and explains how to grow a snowflake in a plastic bottle using dry ice.
