Air guns are good for more than launching potatoes, marshmallows, or testing missile ballistics. Turns out, they’re also really handy for making cars fly.

Originally invented by iconic stuntman Hal Needham, the nitrogen-powered straight fire cannon is an essential tool for modern vehicle stunts. They’re often used in film and television, for shots considered too dangerous to be performed by actual stunt drivers. It works on the same principle as a toy pop-gun—using air pressure as the propellant, rather than combustion.
