Pop Rocks are made of sugar, corn syrup, baking soda, and flavoring. When Pop Rocks are dropped into a soda, the baking soda reacts with the acid in the soda, causing a release of carbon dioxide gas. This gas forms bubbles that rise to the surface of the soda, creating the familiar fizzing effect.
The type of soda can affect the reaction between the Pop Rocks and the soda. Some sodas, such as cola, contain a higher concentration of acid than others, such as root beer. This means that the reaction between Pop Rocks and cola will be more intense, resulting in more bubbles and a stronger fizzing effect.
In addition, the flavor of the soda can also affect the reaction between the Pop Rocks and the soda. Some sodas, such as orange soda, contain citric acid, which can give the Pop Rocks a sour taste. Other sodas, such as root beer, contain a sweeter flavor, which can make the Pop Rocks taste sweeter.
Overall, the type and flavor of the soda can affect the reaction between the Pop Rocks and the soda, resulting in different fizzing effects and taste experiences.
