Engineers test the safety of a new car by running a crash test, which shows whether the airbags inflate properly. When the car detects a crash, a small amount of sodium azide (NaN3) stored behind each airbag is heated. The sodium azide breaks down into sodium metal (Na) and nitrogen gas (N₂). The nitrogen gas inflates the airbags in less than one-tenth of a second! This design helps to keep people inside cars from getting seriously injured in a crash.
