Some Hungarian engineers got together and built a fire extinguisher using two Mig-21 jet engines. It was specifically designed to extinguish pipeline and oil drilling fires. As you can see from the video (after the jump), it really makes fires wish they had never started. And it makes me wish I had two spare jet engines lying around. Not that I'd make a fire extinguisher, because I wouldn't. No, I'm building the world's fastest couch, and I think those are just what I need for a speed boost. Because right now my top speed is like, well, 0. It's a pretty slow couch, it just sits there.
