The purpose of the Pop Rocks activity is to teach about sound waves. The activity involves using Pop Rocks candy and a soda can to demonstrate how sound waves work. When the Pop Rocks are placed in the can and a balloon is placed over the top, the pressure from the carbon dioxide gas in the Pop Rocks causes the balloon to pop. This popping sound is created by the sound waves produced by the pressure of the gas. The activity helps students understand how sound waves travel and how they can be used to create different sounds.
