Brain Freeze (I Get It!) Ice Cube Molds
Brain Freeze ice cube trays aren't just cleverly named, they're -- yes, that's all they are. $8 takes home the piece of molded rubber and another couple bucks brings home some food coloring. Mix all that shit together with some tap water, say a magic prayer, and you've got yourself a party! Did I mention booze? You're gonna need booze. Plus some womens. Preferably skanky.
