Gobstopper

A gobstopper, also known as a jawbreaker in Canada and the United States, is a type of boiled sweet. It is usually round, and usually ranges from 1 to 3 cm (0.4 to 1.2 in) across; though gobstoppers billed as having a diameter as large as 3.25 in (83 mm) have been marketed.
The term gobstopper derives from "gob", which is slang in the United Kingdom and Ireland for mouth. The sweet was a favourite among British schoolboys in the first half of the twentieth century; author Roald Dahl, who wrote about a jar of gobstoppers featuring in the prank he played in his local sweet shop in 1924, also referred to them in his fictional Everlasting Gobstopper which was featured in his 1964 children's novel Charlie and the Chocolate Factory.
A gobstopper usually consists of a number of layers, each dissolving to reveal a different colour, and sometimes flavour. A gobstopper is too hard to bite without risking dental damage (hence the name "jawbreaker").
Gobstoppers have been sold in traditional sweet shops for at least a century, often by weight from jars. As gobstoppers dissolve very slowly, they last a very long time in the mouth, which is a major factor in their popularity.
Gobstoppers are made by slowly depositing layers onto a core, such as a pressed ball of sugar, a single seed of anise or a gumball. Gobstoppers are made in large, rotating, heated pans in a process known as "hot panning". The sweets take several weeks to manufacture, as the process of adding liquid sugar is repeated multiple times. Natural and artificial colours and flavours are also added during the panning process.
The Everlasting Gobstoppers, sold under Nestlé's Willy Wonka Candy Company brand, were first introduced in 1976 by Breaker Confections, and are named after the Everlasting Gobstoppers in Roald Dahl's children's book Charlie and the Chocolate Factory. In Dahl's story, Everlasting Gobstoppers are purported to last forever. Dahl named the sweet after gobstoppers, which were a favourite among British schoolboys between the two World Wars. A jar of gobstoppers featured in the prank Dahl played on the owner of his local sweet shop in 1924, which he recorded in his autobiography Boy: Tales of Childhood.
In the 1964 children's book Charlie and the Chocolate Factory, Roald Dahl described "Everlasting Gobstoppers," a fictional gobstopper that could never get smaller or be finished.
The animated series Ed, Edd n Eddy revolves around jawbreakers. Most episodes feature the title characters running a variety of scams to earn money to buy the confections. The jawbreakers in the show are depicted as comically oversized, often with a circumference larger than that of the heads of the characters; characters' cheeks would balloon to the same size when these jawbreakers were placed in their mouths. Jawbreakers are also the main subject of one of the show's tie-in video games, Ed, Edd n Eddy: Jawbreakers!.
The 1999 American teen comedy Jawbreaker centres around the main characters accidentally killing their friend after gagging her with a jawbreaker.
In 2003, Taquandra Diggs, a nine-year-old girl in Starke, Florida, US suffered severe burns, allegedly from biting on an exploding Wonka Everlasting Gobstopper that had been refrigerated, left out in the sun, then refrigerated again. Diggs and several other alleged victims' families filed lawsuits against Nestlé for medical bills resulting from plastic surgery as well as pain and suffering; the matters were later settled outside of court for an undisclosed amount.
