Listen as curator Dedo von Kerssenbrock-Krosigk describes this trick goblet, which holds a separate "straw" whose finial resembles the head a stag. To drink from it, one has to suck the liquid through the mouth of the stag while covering a hole in the stem of the vessel. Thus, this glass is a perfect device to fool a guest during a drinking game. The Germanic countries have a long tradition of playing elaborate games in high society. Drinking vessels were made from inorganic materials such as glass and silver, as well as from organic materials, including exotica such as ostrich eggs and coconuts. They are typically devised in such a way that the playing participant at a party would spill his drink—and create amusement—if he was unfamiliar with how the vessel functioned.
