This video by Russian outdoors-man and survivalist Grigoryi1 has gone viral.

Having canned food while lost in the woods is a great form of sustenance. But how helpful is the food if your missing a can opener, and can’t open the can?

Thankfully, Grigoryi1 explains how to open a tall tin can with nothing more than a pair of hands.

Though his entire narration is in Russian, his demonstration is explanation enough for most viewers.
