The Hidden Straw Holder
One of the most useful functions of the pull-tab hole is something many people discover only by accident.
After opening the can, the tab can be rotated so that the hole lines up directly over the drinking opening.
When positioned this way, the hole acts as a holder for a straw.
Simply place the straw through the opening and into the can.
The tab helps keep the straw from moving around while you drink.
