And I got my formula wrong on the other one... mean N20 apparently. What do I know, last science class I had was in high school...
http://en.wikipedia.org/wiki/Nitrous_oxide
Nitrous oxide, commonly known as "laughing gas", is a chemical compound with the chemical formula N2O. At room temperature, it is a colorless non-flammable gas, with a pleasant, slightly sweet odor and taste. It is used in surgery and dentistry for its anesthetic and analgesic effects. It is known as "laughing gas" due to the euphoric effects of inhaling it, a property that has led to its recreational use as an inhalant drug. It is also used as an oxidizer in rocketry and in motor racing to increase the power output of engines. It is often created in bushfires.
Ah, nitrous, is there anything you CANT do?
