Pop Rocks are a type of candy known for their unique popping sensation when they dissolve in your mouth. They are made by adding carbon dioxide gas to a sugar mixture, which creates tiny bubbles. When the candy is eaten, these bubbles burst, producing a fizzy sound and feeling. Originally created in the 1950s, Pop Rocks gained popularity in the 1970s and have since become a nostalgic treat for many. They come in various flavors, such as cherry, grape, and watermelon, and are often enjoyed as a fun addition to desserts or snacks.
