Why do Pop rocks pop?
Pop Rocks is one brand of carbonated candy that was conceptualized by a research chemist William A. Mitchell of General Foods in 1956. Pop Rocks is a mixture of sugar, lactose, corn syrup and flavoring that makes it significantly distinct from other candies because it creates a fizzy reaction when placed inside the mouth. The manufacturing process of this candy is done by mixing, heating and cooling the ingredients. The process, which produces carbon dioxide gas, builds up high pressure bubbles in the candy. Such bubbles can only be viewed through the use of a microscope. Tracing its history, Pop Rocks was first sold in the market in 1975 and after 8 years, the production halted due to some issues that was, at that time, needed to duly addressed and given attention to. The main concern of many consumers at that time was about the spreading urban legend that eating Pop Rocks with carbonated drinks would cause the stomach of the person to be exploding. As this speculation started to spread, the company decided to stop its production, which only added fame to the surrounding myth.
With this type of candy being made available to consumers, many people have become evidently surprised and curios that Pop Rocks pop. The reason why Pop Rocks pop is because of the carbon dioxide contained in the candy. The process that the candy undergoes creates carbon dioxide that is trapped to permit the candy to pop. Pop Rocks pop only when it comes in contact with the saliva, which triggers the candy to break and dissolve, thereby releasing the carbon dioxide from the bubbles. As the gas is released, it creates a popping and sizzling sound. It also leaves a minor tingling sensation in the mouth as it further dissolves.
