This is a simple game that requires a couple of tools: a pitcher of beer, a shot/short glass and nerves of steel. Float the small glass in the pitcher; you may have to put a couple drops of beer in it to stabilize the glass. Each player goes in turn to pour a little beer from their glass into the floater. The one who sinks it, drinks a beer. Strategies we've seen include filling the glass until just about to break the surface so the next player will inevitably sink it; and twirling the pouring glass with such subtle precision as to release only a small drop, thereby thwarting the previous strategy. Cheaters have been know to discretely shake the table at opportune moments.
This game is also known as Sink the Battleship.
