Brazil-based design student Mauricio Harion's got an interesting side gig: He founded the Mixing Bar, an organization that "[provides] support for bars that are interested in quality cocktails and private events that call for special cocktail services. Works include: General interior design, menu creations, staff training, work dynamics and optimization of the work space, etc."

His design for the "Battleship Drinking Game" mixes his two worlds well:

It's played just like the usual Battleship game with one addition. If you miss the target you drink a sip of water, and if you hit an enemy boat you opponent empties the corresponding shot glass.

If only World War II's actual naval battles had been settled this way.... Then again, throwing up inside a submarine is probably no fun.
