[edit] Background and history

The idea of the product was patented by General Foods research chemist William A. Mitchell in 1956.^[1] The Pop Rocks candy was first offered to the public in 1975. Around 1983, General Foods stopped selling the candy. Some incorrectly believed that this was because of an urban legend that mixing Pop Rocks with carbonated soda could result in a person's stomach exploding. In fact the candy was withdrawn for reasons largely owing to its success in the marketplace and to its relatively short shelf life. Distribution was initially controlled to ensure freshness, but with its increasing popularity unauthorized redistribution from market to market resulted in out-of-date product reaching consumers.^{[citation needed]} In 1985, Kraft Foods bought the rights to the candy product and remarketed it as Action Candy through a company called Carbonated Candy. Since 1979, Zeta Espacial S.A., a company based in the municipality of Rubí in Barcelona, Spain, has manufactured, sold, and exported the product under the brand name "Fizz Wiz".

In 2006, Dr. Marvin Rudolph, who led the group assigned to bring Pop Rocks out of the laboratory and into the manufacturing plant, wrote a history of Pop Rocks development. The book, titled Pop Rocks: The Inside Story of America's Revolutionary Candy, was based on interviews with food technologists, engineers, marketing managers, and members of Bill Mitchell's family, along with the author's experience.

A similar product, Cosmic Candy, and previously called Space Dust, was in powdered form and was also manufactured by General Foods.^[2]

[edit] Manufacturing

The candy is made by mixing its ingredients and heating them until they melt, then exposing the mixture to pressurized carbon dioxide gas (about 600 pounds per square inch) and allowing it to cool. The process causes tiny high pressure bubbles to be trapped inside the candy.^[3] When placed in the mouth, coming into contact with saliva the candy breaks and dissolves, releasing the carbon dioxide from the tiny atmosphere bubbles, resulting in a popping and sizzling sound and leaving a slight tingling sensation. The bubbles in the candy pieces can be viewed when aided by a microscope.

[edit] Urban legend

During the product's heyday, rumors persisted that eating Pop Rocks and drinking cola would cause a person's stomach to explode. The company spent large sums sending out flyers to debunk the rumor. This is, in part, caused by the false assumption that pop rocks contain an acid/base mixture (such as baking soda and vinegar) which produces large volumes of gas when mixed through chewing and saliva.^[4] One of these myths involved a child named Mikey from the Life cereal commercials. Mikey was reported to have died after eating a Pop Rocks and cola mixture. The rumor is false: Mikey is alive.^[4]

Because of the unique nature of the legend, and the duration of its perpetuation, the story has appeared in many other forms of media and fiction. The U.S. TV series MythBusters examined the rumor by mixing Pop Rocks and cola inside a pig's stomach, and concluded that an explosion was impossible without eating pounds of the material.^[5]
