The Chemistry of Snowflakes

“The Chemistry of Snowflakes” by Bytesize Science explains how snowflakes form and why, despite their widely varying forms, they are often hexagonal.

The video tracks formation of snowflakes from their origins in bits of dust in clouds that become droplets of water falling to Earth. When the droplets cool, six crystal faces form because water molecules bond in hexagonal networks when they freeze.
