N2O is a gas produced during the burning of fossil fuels and has always existed in nature.
In 1799, English chemist Humphry Davy was the first to discover the strange properties of N2O gas. He and his colleagues collected the gas produced by heating ammonium nitrate crystals in a green silk bag. After removing impurities, they inhaled it through a pipe.
For his own research, Davy gave this gas to both patients and healthy people to inhale and recorded their sensations.

It was not until 1844 that Dr. Horace Wells used N2O gas in medicine. He used this gas to help patients with tooth extraction to reduce pain.
Later, N2O was also applied for other purposes. N2O gas really became famous after the Fast & Furious series or the Need for Speed game series was released. To increase speed, you just need to press the NOS button, also known as Nitro. At that time, the N2O gas tank is pumped into the engine, causing the atomic bond between Nitrogen and Oxygen to be broken, the amount of oxygen in the combustion chamber is suddenly increased, making the combustion process stronger. The piston will move faster and the speed of the car increases.
N2O gas helps cars accelerate in the movie Fast & Furious.
N2O gas can cause excitement and the desire to laugh, so it is also called laughing gas. Currently, N2O gas is used quite a lot in entertainment venues for young people.
