Here's an awesome package design concept done by Spain-based design student José Luis García Eguiguren. His Mixed Emotions concept keeps vodka and one of a variety of mixers in the same bottle, but separated like epoxy; when it's time to quaff, you pop the top, put your mouth to the dual tubes and you've got a party in your mouth.
Eguiguren's vision (hit the jump to read it in his own words) is that the different mixer's flavors--strawberry, passion fruit, etc.--would evoke different emotions in the imbiber. And hopefully the bottles are made out of plastic, so whomever drinks that "vodka + anger" mix on the right can't smash the thing over a fellow partygoer's head.
