Everyone has been there. You've got a can of something tasty that you need to open, but you can't find your can opener! Its extremely annoying, particularly if you have to sacrifice the food because of this. Well, never be stuck in that irritating situation again thanks to this YouTube video created by a guy who calls himself the Crazy Russian Hacker. It shows you how to open canned goods with no can opener or any kinds of tools. All you need is access to some concrete or other kind of paving type material (which can stay firmly affixed to the ground). This is billed as a zombie apocalypse survival technique, and while it would definitely be handy in this kind of life or death situation, it's also useful for anyone who simply can't keep their kitchen drawers in order.
