How do modern airbags work?
CRASHES trip sensors in cars that send an electric signal to an ignitor. The heat generated causes sodium azide to decompose into sodium metal and nitrogen gas, which inflates the car’s air bags. Under normal circumstances, this molecule is quite stable. If heated, though, it will fall apart.
