Have you ever been camping or enjoying the great outdoors and realized you have no way to open all of the canned food items you brought to eat? Also, a lot of people are making their preparations for the Zombie Apocalypse and canned foods will be a big part of your survival kit, but without a can opener...how will you eat? Simple, use your hands. Now you're asking, how in the Sam heck do you open a can easily with just your hands? This video demonstrates how easy it really is and you don't need any kind of tool whatsoever. This is the mother of all survival tips!

All you have to do is find a piece of concrete, turn the can top down and begin rubbing the top of the can back and forth on the concrete. A few seconds later, turn the can over, and gently squeeze the sides of the can and watch the lid just pop off. Yeah, it's really that easy.

It has something to do with the friction that builds up where the top of the can is sealed. Watch the video and then try it yourself...you know you want to. I tried it and guess what? It worked!! just as easily as in the video. I opened a can of tuna. Amazing...who knew?
