POP ROCKS® are small pieces of hard candy that have been gasified with carbon dioxide under superatmospheric pressure. When these sugar granules come in contact with moisture, in someone’s mouth or in water, soft drinks, etc, the candy dissolves and the gas retained inside the carbon dioxide bubbles is released, causing those crackling and fizzing sounds. And, no, nobody exploded from eating POP ROCKS® and drink soda. But the rumors became so bad that the FDA even set up a hot line in Seattle (WA) for people to call to dispel the rumor and assure parents that the candy was safe for children and it would not cause the stomach to explode if mixed with carbonated drinks. Now that you know POP ROCKS® are completely safe, don't be shy and browse our selection of delicious POP ROCKS® available in many flavors!
