Any attempt to fill a car, room, or bag over your head with nitrous oxide could cause fatal oxygen starvation. Strapping on medicinal gas masks attached to cylinders of pure N2O can also kill (in medical use, masks usually deliver a 50% nitrous oxide, 50% oxygen mix).
Is NOS the same as laughing gas?
Laughing gas is the common name for nitrous oxide or N2O. It is also known as nitrous, nitro, or NOS. It’s a nonflammable, colorless gas that has a slightly sweet flavor and odor.

Who named Aluminum?
What came first aluminum or aluminium?
The American Chemical Society (ACS) officially adopted aluminum in 1925, but in 1990 The International Union of Pure and Applied Chemistry (IUPAC) accepted aluminium as the international standard. And so we land today: with aluminum used by the English speakers of North America, and aluminium used everywhere else.
