Remake of Pythagoras Cup

A Pythagorean cup (also known as a Pythagoras cup, a Greedy Cup or a Tantalus cup) is a form of drinking cup that forces its user to imbibe only in moderation.

Credited to Pythagoras of Samos, it allows the user to fill the cup with wine up to a certain level. If they fill the cup only to that level, the imbiber may enjoy a drink in peace. If they exhibit gluttony, however, the cup spills its entire contents out of the bottom (onto the lap of the immodest drinker).
