How to open a can without a can opener requires resourcefulness. One method is to use a sturdy knife or spoon's edge to puncture and cut through the lid's rim by applying pressure and rotating carefully. Alternatively, try rubbing the lid against a rough surface, like concrete or a brick, to wear down the edge until it weakens and can be pried open with a spoon or other blunt object. Another approach involves heating the sealed can in boiling water for a few minutes to expand the metal, making it easier to pop the lid with a spoon or knife.
