What makes Pop Rocks pop?
Pop rocks (“Gasified Candy”) are made with a sugar syrup that is VERY hot. That syrup is mixed with C02, (carbon dioxide) at about 600 pounds per square inch, which forms tiny bubbles in the syrup. Once the syrup cools, it cracks into pieces, and those pieces still contain bubbles of C02 under high pressure. When you put the pieces in your mouth they melt, and that releases those CO2 bubbles with a loud POP! From it’s patent application: Gasified candy which produces a more pronounced popping sensation is prepared by maintaining a sugar melt at a temperature of below about 280° F. during gasification. This product contains observable gas bubbles with a majority of the large bubbles having a diameter greater than about 225µ which is substantially larger than those in the gasified candy produced heretofore. http://science.howstuffworks.com/question114.
