In a recent study at the University of Bristol, young people drank beer faster when it was served to them in a curved, fluted glass. It's a small study, but the researchers think it could be a first clue toward understanding why we sometimes get more drunk than we meant to do. Researchers found it was difficult for people to judge volume of liquid in a curved glass, which might mean it's also harder to pace drinking. (Via Noah Gray)
