Claim:
An aluminum can puncturing device comprising: a barrel that attaches to and retracts partially within a brass cap; wherein the barrel and the brass cap resemble a shotgun shell; wherein a pin is mounted to said brass cap, such that upon partial retraction of the barrel, the pin is revealed and is used to puncture a vent hole in an aluminum can prior to opening said aluminum can in order to shotgun a beer; wherein the barrel retracts partially within the brass cap via an outward lip located on the barrel that interacts with an inward lip located on the brass cap such that the interaction between the outward lip and the inward lip acts as a stop to prevent the separation of the barrel from the brass cap; wherein the barrel has a top and a hole located in said top; wherein the pin passes through said hole; wherein a spring is contained within a compartment formed between the brass cap and the top of the barrel such that the barrel is fully extended when not in use.
