How to Open a Can Without a Can Opener?
If you are left out in nature without a can opener, you can still open your food by using two hands. First, find an abrasive surface like rocks. Turn the can over so that it is facing down and rub away at the ridges until the metal is smooth. The grip will change from tight to loose, which makes it easier to squeeze later on. When you are ready, hold the can in one hand and use the other hand to squeeze it closed. The food should come right out!
