Shotgunning

Cans off ( also canned shooting, Cossacks pump, turbo beer or woodcutter, American and shotgun ) is a method by which a can of beer can be drunk very quickly. To this end, the can is provided with an additional opening ( " pierced " ) so that when drinking from one of the two openings, the air can flow into the can through the other opening above the liquid level. In this way it is prevented that the liquid level is located above a negative pressure. Otherwise, the air would have to flow back through the drinking opening and rise in the form of bubbles through the liquid.

The doses stinging may serve as a drinking game, being drunk at the time. The attachment of the additional opening is often done with knives, screwdrivers, keys or similar improvised tools.

With a 0.33-liter box with a height of 115 mm, the liquid level is about 90 mm ​​above the outlet opening. Therefore, under Torricelli, an initial outflow velocity of 1.3 m / s The per second exiting beer volume results from multiplying the discharge velocity by the area of the aperture, corrected by the empirical factor 0.63 for thin-walled vessels.

The College movie The Sure Thing 1985 includes a scene in which John Cusack a can of beer empties in this way, the slang term " shotgun " for the ritual is detected in American since 1983. 2012 brought the American Miller Brewery a specially prepared for light beer can cans stinging called " Punch Top Can" on the market, in which the plate on the top is thinner than normal.
