you are hearing and feeling is the 600-psi carbon dioxide gas being released from each bubble. around 1983 the pressure from worried parents became to much so Pop Rocks had to be taken off the market.
When the soda is at a higher pressure, it can hold more carbon dioxide. 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). The solution is heated until the water boils off and combined with carbon dioxide gas at about 600 pounds per square inch (psi).

When the soda is opened to the atmosphere, the pressure decreases and the carbon dioxide comes out of the solution as bubbles. Main Chemicals, Compounds, Components, chemistry's Role, pop Rocks is a hard candy that have been crystallized with carbon dioxide using a patented process.
