How to use a bottle opener?

A bottle opener is a device that enables the removal of metal bottle caps or caps of the glass bottles. This uses the specialised lever that inserts beneath the metal caps. This is then used to give fulcrum to the pleated metalwork on which it pivots.

On the other hand, the other side of these openers is used to open the cans. As a result, the cans of beer and soft drinks need holes in the can to help in drinking from them. These also come in handy for cans having juice or similar liquids. Levers are, therefore, rigid and rod-shaped objects that have a fulcrum so that the same makes it easier to open.
