The Everlasting Gobstopper is a gobstopper candy from Roald Dahl's 1964 children's novel Charlie and the Chocolate Factory. According to its creator Willy Wonka, it was intended "for children with very little pocket money". It not only changes colours and flavours when sucked on, but also never gets any smaller or disappears. In 1976, the name of the fictional candy was used for a product similar to a normal gobstopper, or jawbreaker.
Although only briefly mentioned in the book and its 2005 film adaptation, the 1971 film adaptation Willy Wonka & the Chocolate Factory used the Everlasting Gobstopper as a plot device in which Wonka's business rival Slugworth attempts to bribe the children visiting the Wonka factory to steal one for him. This is later revealed as a lie; Slugworth is actually Mr Wilkinson, one of Wonka's workers. The proposal is a test Wonka set up to judge the worthiness of the ticket holders to take over the factory, given to all five children.
An actual Everlasting Gobstopper prop used in the 1971 film was sold for $US100,000 to the owners of the television show Pawn Stars.[1]
