But Pop Rocks are processed with Carbon Dioxide. The ingredients are heated together and boiled. The hot sugar mixture is mixed with carbon dioxide gas at about 600 PSI. The carbon dioxide gas forms tiny, 600 PSI bubbles in the candy. Once it cools you release the pressure and the candy shatters, but the pieces still contain the high-pressure bubbles (look at a piece with a magnifying glass to see the bubbles).
