Open a Bottle With a LighterThis impressive party trick works just as well when you're spending a night in. Using your forefinger as the fulcrum instead of your thumb reduces the chance of the bottle cap flying in your face. To open your bottle, grab another beer from the six-pack and hold it upside down to interlock the two caps. Hold the bottle with one hand and rest the bottle cap on the edge of your counter. Open a Bottle With PaperWhen nothing else is available, a sheet of paper makes for an unexpectedly effective bottle opener.
