It's easy to SHOTGUN with the Shotgun Key!

1)  Punch a hole in the side of the can with a Shotgun Key. 

Using the Shotgun Key, puncture a hole near the bottom while the can is tilted in an almost upside-down position.  By tilting the can the puncture will go through the can and into the area occupied by the air pocket which will help prevent any of the fluid from escaping.  Use the Shotgun Key to adjust the size of the hole to your preference. 

2)  Place your mouth over the puncture hole, tilt the can to an upright position and pop the tab in the usual manner. 

Once the tab is pulled the combination of vacuum release, pressure change and gravity flow allows the beverage to escape the can at a very high rate of speed.

3)  Commence drinking the beverage as fast as possible and until the can is empty. 

Typically a beginner can consume 12 fluid ounces between 8 to 10 seconds.  A skilled and experienced shotgunner can consume this amount in as little as 3 to 4 seconds.

When shotgunning beverages containing alcohol never consume more than one beverage per hour.  Never drink and drive.
