Get ready for Green Apple grenades. A packet of tiny crunchy candy rocks that taste great and pop and explode as you chomp away. It creates a fun, fizzle fest in your mouth and can be used simply is cakes and other homemade treats. Pop some in the basket today. Want to know more? Here’s a bit of science behind the tastiness – 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 water, milk, soft drinks, etc, the candy dissolves and the gas retained inside the carbon dioxide bubbles is released, causing characteristic crackling and fizzing sounds.
