The experiment is another example of the chemical interaction between acids and bases. In the experiment, a closable plastic lunch bag is filled with warm water and vinegar, and a wrapped packet of baking soda is added. The bag is closed and the reaction between acid (vinegar) and baking soda (base) creates pressure by generating gas (carbon dioxide) within the bag. The bag swells and usually explodes (ruptures) unless the pressure escapes. This shows that a chemical reaction can indirectly release energy as it forms new chemical compounds.
