The Chemistry of Snowflakes
How snowflakes are formed.

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. It explains that ice crystals grow fastest at the corners between the faces, fostering development of the six branches that exist in most snowflakes. As snowflakes continue to develop, the branches can spread, grow long and pointy, or branch off into new arms. As each snowflake rises and falls through warmer and cooler air, it thus develops its own distinctive shape.
Sulfur Hexafluoride
What happens if you inhale Sulfur Hexafluoride (SF6)? As this Chemistry teacher explains, the heavy molecules of gas slow the vibrations of the vocal cord, decreasing pitch quite dramatically. A good illustration of Grahams Law which states that effusion of a gas is inversely proportional to the square root of the mass of its particles.
