The Magic Box That Makes the Car Go Vroom

There's something on a car called a differential. We don't know what that is, but I did some research. It's the magic box that makes the car go vroom. So this magic box on the Ford Pinto had four protruding bolts facing the gas tank. Lawyers would call them can-openers. And we're just going to call them for this show, flaming death bolts.
