This cool new yet quite historic Pythagorean Wine Glass is a prank vessel inspired by the Greek mathematician Pythagoras's greedy cup that functions like a normal wine glass when filled to a moderate level, but instantly drains its contents out through the bottom when filled past a certain point. Originally designed to expose gluttony and promote imbibing in moderation, now it's just funny. It features a concealed inner pipe that creates the siphon effect if filled too high and has a tapered rim and wide bowl to enhance the aroma of the wine for those who know their limits. Makes a cool gift for any wine loving prankster.
