Pop Rock's is the #1 selling popping candy! The Blue Razz flavor is one of the most popular! This carbonated candy is sure to be a blast any time, but share with friends and create laughs as you enjoy this crackling mouth sensation! POP ROCKS® are small pieces of hard candy that have been gasified with carbon dioxide under super-atmospheric pressure. When these gasified sugar granules come in contact with moisture, in someone’s mouth or in a liquid, the gas retained inside the carbon dioxide bubbles is released, causing its characteristic popping sensation as well as crackling and fizzing sounds.
