It would be wonderful if all things opened when told “open sesame”. Unfortunately, most require a little more effort. It’s highly unlikely that you will manage to open a tin can by saying “open sesame”, but one of these methods is sure to work.
A Spoon
One of the easiest utensils to use is a spoon—just make sure it’s not the plastic kind. Place the can on a stable surface and use the edge of the spoon’s bowl to puncture the can’s lid near the edge. Press down and twist the spoon to create a hole. Repeat a few times until you can pry open the can.
Rough Surface
This method is based on friction. Hold the can upside down and rub the lid’s edge in a circular motion against a rough surface like a brick wall or concrete. continue rubbing until the lid weakens or punctures. Be warned: this technique requires a lot of patience.
Heat
When exposed to heat, metal expands. Submerge the can in a pot of boiled water and allow it to sit for 10-15 minutes. Once the metal expands, use a sharp utensil to force out the lid.
