Abstract: The Guzzlegun is a device which will be used to “shotgun” or consume a beverage from metallic can. The Guzzlegun will provide a mouthpiece by which the liquid contents of the beverage will flow through once the Guzzle punctures the bottom of a beverage can. First, a can will be placed into the Guzzlegun. Then the mouthpiece and puncture tube assembly will be snapped closed. During the process of closing the mouthpiece and puncture tube assembly the beverage can is punctured. Next the operator will place the mouth piece into their mouth. Once the mouthpiece is in one's mouth, the top of the can will be opened. Atmospheric pressure and gravity then allow the contents of the beverage can to flow very freely from the puncture tube assembly through the tubular mouthpiece, and finally into the operator's mouth.
