Gobstoppers or jawbreakers are a type of hard candy. Gobstoppers are too hard to bite without risking dental damage (hence the name "jawbreaker"). In Dahl's story, Everlasting Gobstoppers are purported to last forever. In Series 1, the chosen contestants would have been picked from a jar of gobstoppers. Gobstoppers are made in large, rotating, heated pans. They are shiny and dark reddish brown, and hard like Gobstoppers, but generally only across.
