What if the can lid can't be opened?

Put the ordinary rubber band on the bottle cap, so that when opening the can, it will increase some friction, so that the hand will not slip easily, which will make the force greater, and it will be easier to open the can, and it will not be impossible to open it because of slipping.

Put a towel or rag soaked in hot water on the bottle cap for about 5 minutes, and open the bottle cap by using the principle of thermal expansion and cold contraction.
