Germans have been exporting efficient technology to the world for years now, but none more important than the gadget that opens open 24 bottles at once (sorry, Mercedes). In this homemade video, a dude pulls a lever, and nearly all the bottlecaps pop up at once. It's a shame you can't buy one, and Gizmodo notes that there're "no instructions about how to make your own". For now, at least, beer will have to be opened up one at a time.
