What is the Chemical Formula of Laughing Gas?

Laughing gas is a completely colorless, non-flammable gas at room temperature, with a slightly sweet, metallic smell and taste. As the formula N₂O shows, each massive molecule of laughing gas is perfectly built using exactly two Nitrogen atoms (N) heavily bonded to one Oxygen atom (O).

Laughing gas doesn't magically force your stomach to laugh like a cartoon. When you inhale N₂O, the gas aggressively enters your bloodstream and rushes into your brain. It violently blocks the brain's pain receptors and floods the brain with 'Dopamine' (the extreme happiness chemical). Because the brain suddenly feels zero pain and massive euphoria, the person enters a state of deep, dizzy happiness, often causing them to uncontrollably giggle or 'laugh' at nothing.

1. Medical Surgery: It is heavily used by dentists and surgeons as a mild 'Anesthetic' (pain-killer) to calm down terrified patients before a painful surgery.
2. Car Racing (NOS): In the massive street racing industry, liquid N₂O (called NOS) is violently injected into car engines to give the car an explosive, massive boost of speed.
3. Food Industry: It is the exact gas used to aggressively push whipped cream out of aerosol spray cans.
