here's how to do what we called a shotgun. lie the can on its side,and on the side of the can, at the bottom, punch in 2 V's beside each other with the v shaped can opener and bend in the remaining v in the middle between the 2 holes, suck the air out of the hole, tip the beer straight up with your mouth still on the hole not letting air in, then pull the tab to open, the beer shoots down your throat through the V hole unbelievably fast.
