After Dark: Fire and Ice: Pyrograph in Slow Motion (clip)

Running Time:
00:00:52

Slow motion footage of Pyrograph, a work by Earl "Dodger" Stirling that has been described as a cross between Dante's Inferno and the Foucault Pendulum. Like a fiery version of the Exploratorium's classic Drawing Board exhibit, Pyrograph swings a pendulum across a sandy, flaming cauldron and traces out oscillating patterns in colorful fire.

After Dark: Fire and Ice: Magnesium Burning in Dry Ice (clip)

Running Time:

Most things won't burn on Mars—after all, the main ingredient in the Martian atmosphere, carbon dioxide, is used in fire extinguishers on earth. So how would one create fire without oxygen? Use metal!This slow motion footage shows magnesium burning within a block of dry ice.

Ice Stories: Snow Chemistry (webcast)

Running Time:
00:22:08

As the Arctic continues to warm, chemicals locked in the snow can be released-either into the seas or evaporated into the air. Dr. Glenn Rowland studies the chemicals locked in the ice to help us understand what is there now and how it will react when released into the environment.
