Pop rocks is my childhood favorite candy. Pop Rocks have many different flavors, Strawberry, Watermelon, Tropical, Blue Razz, Original Cherry, Cotton Candy, Grape and Strawberry Sugar Free are available year round. Pop Rocks Bubble Gum and Pop Rock sticks are also available in a standard way. But also look for all the new limited editions that are launched regularly: Chocolate, Pumpkin Patch Orange and Candy Cane. The Blue Razz was definitely my favorite.I have always wondered what was in them to make them pop in my mouth. So this paper is about to answer my question. William A. Mitchell is a famous chemist, also the inventor of Pop Rocks or also known as space dust. He was working on an instant soft drink and stumbled upon this candy by chance. Pop rocks are lactose, corn syrup, and flavoring. But it is also processed with carbon dioxide. what they do is heat the ingredients together, bringing the mixture to boil.  They continue to boil it until the moisture level descends suitably so that a thick syrupy substance remains.  In normal hard sugar candies, this substance is then put in molds and allowed to cool and harden.  With pop rocks, they expose the hot mix to carbon dioxide at about 600 pounds per square inch worth of pressure.  This ends up forming very small bubbles of carbon dioxide within the mix.  The substance is then cooled and then hardens. Once the hard candy is formed, the pressure is released.  This causes the candy to shatter, leaving small pieces of hard candy, which are the Pop Rocks.  Many of these pieces still contain pockets of carbon dioxide kept at  high pressure.  When the candy hits the saliva in your mouth, it quickly dissolves the thin barriers containing the pressurized carbon dioxide.  This results in the bubbles bursting fairly quickly, releasing the trapped carbon dioxide, often with strong force to cause the candy to pop in your mouth.After the candy hit the market, parents had some huge concerns. The General Food Company had to make a telephone hotline to assure parents that this candy will not make children choke, also using these carbonated candy they thought that it could make your stomach explode, that clearly was not the case. They took out full-page ads in 45 majors publications, wrote some 50,000 letters to school principals around the country, and sent William A. Mitchell on the road to explain to all that Pop Rocks generate less carbonation than half a can of soda, also that the common sensation in your mouth is the same as drinking soda, sparkling wine, and beer.  It didn’t stop there though. People would mix the Pop Rocks with Coke to make an explosion, or sometimes even drink it to see if you would explode. Adam Savage and Jamie Hyneman tested the legend in 2003 to see if it was false. They poured six cans of soda and six pouches of Pop Rocks into a pig’s stomach. While the stomach grew to three times its original size, it did not explode, and that’s when everyone knew that it was false. Pop rocks were discontinued in the 1980’s.  Pop Rocks. (n.d.).
