What did I learn today? I learned a quick and easy secret that will open any can in short order in the event I don't have a can opener. Now I must pass along this awesome knowledge!

These Russian guys are pretty cool. Not only do they mention in the video many times that they have lots of tools, they knew something I didn't. How to open a can without a can opener. Not only that, but just using your bare hands and a flat piece of concrete or a flat rock. Basically all you have to do is just scrub the top around on the rock till it gets chewed down a bit and squeeze? For real though, check this out and you will survive in a world without tools! Guess what? Even the cat can survive! (that was the funniest line from the video)
