Drinking a can of soda is one of the few truly international activities in the world. There are a numbers of sodas out there. Are they sodas or pops or soda pops or a Coke, a Pepsi, a etc. Whatever you call them or how you drink them, its nice to sit with some friends in the heat, and pop a nice cold can. Hear the sloshy thunk of the 2 cans as you toast your buddy and anyone else choosing to be together at this time.
A long pointed instrument.
Take the can and hold it in such a fashion that your thumb is in the middle of the can below the mouth. Make sure you hold the can tight, but not tight enough to dent it.
Place the thumb of your opposite hand and place it directly on the rim of the can in front of the mouth. The pad of the thumb should be pushing against the side of the can and pointing toward your other thumb.
Place the nail or the -pad of your middle finger under the “tab” of the can. Pull the tab in such a fashion that you are trying to touch your thumb and middle finger together. 3/4 of the way, stop applying pressure with your thumb, and bring your middle finger straight down till the tab hits the rim of the can. With your thumb, push the tab back into place. If you prefer, but it is very dangerous, you can now push the broken piece of tin farther back into the can. Many prefer to have no obstructions in the mouth of their soda.
Sometimes it becomes necessary to use a tool to open a can of soda. Hold the can as above, with the opposite hand you would use to hold the can normally. There are gadgets that are specificly designed to open a can of soda, but very few people have these gadgets.
Take a tool that is very skinny, think enough to pry something, pointy is preferable, and is at least 8 inches long. Your should be in the middle of the can, in the exact opposite as you were holding it to open it by hand. The rim where the mouth is should be directly opposite the part of the rim of the can, your thumb should be directly below this point.
With the can where your fingers are pointing diagonally away from you, slide the tool under the tap till it hits the attachment in the center. Lift the tool up so that your thumb lowers and finally become stuck pointing down. Take your thumb and push it down the other way, and then replace it back to the original place it started.
The rim of the mouth is very sharp and will cut you easily.
A lot of charities will take the tabs of can to benefit many sick children. Please look into that.
