We’re going to launch a rocket by building up pressure using a chemical reaction. I really like this experiment because it combines chemistry, gas pressure, and Newton‘s laws of physical motion all in one cool experiment.
For every action, there is equal and opposite reaction. Your rocket generates a high pressure through a chemical reaction. The alka seltzer and water combine to form carbon dioxide gas (CO2) which builds until it pops the lid off your film canister. The lid flies one way and the tube goes the other. Newton’s Third Law in action!
