Liquid nitrogen

Liquid nitrogen, or N2 in scientific terms is nitrogen gas that has been cooled to 63.15k or below, at which point the gas will condense into a liquid.

Liquid nitrogen is a specialty of Spacesim. Liquid nitrogen is used for the EEP as a demonstration of how cold it can become on the outer planets, namely Neptune. It has also been used for publicity, usualy involving freezing marshmallows and impressing potential sim members with "Mad Science Skillz!". It was particularly effective as part of the Week'O'Hype.

Liquid nitrogen has also played a part in Sim Lore, being used in such stunts as the smoking bottle of doom and the Toilet of Doom.
