Pop Rocks contain carbon dioxide gas that is trapped in the candy during the manufacturing process. When the candy is heated and then cooled, the pressure of the gas creates small pockets within the hard candy. When the candy dissolves in your mouth, the pressure is released, causing the characteristic popping and crackling sensation. The ingredients typically include sugar, lactose, and flavorings, along with the carbon dioxide.
