What’s going on?
Baking soda—also known as sodium bicarbonate—and vinegar—or acetic acid—react when they are mixed. A chemical reaction is when two or more substances combine and create a new substance. The atoms in the substances are breaking apart and forming new combinations. When this happens, there is an observable reaction. This could be the formation of a gas or heat.In the baking soda and vinegar reaction, carbon dioxide (CO2) is produced. This fills up the bag. As the CO2 continues to build up in the bag, it has to go somewhere.
So the bag explodes
