Conventional wisdom has always said that no two snowflakes are alike—until now.

Kenneth Libbrecht, a Caltech physics professor, has created nearly identical “designer snowflakes” out of ice crystals in his laboratory, where he studies the molecular dynamics of crystal growth, especially ice crystal growth.

Libbrecht also takes amazing photos of natural snowflakes and has produced videos of designer snowflakes growing in the lab.

In this video, he explains how he does it.
