Don't have a can opener? This is how you will open cans without it

At that moment you probably feel like there is nothing to do, and that luck has not been on your side that day, but it turns out there is an easy method to open cans without a can opener, or any other tool.

All you have to do is find a hard surface, preferably concrete, and just rub the can on it.
