Pop Rockets
Students design and build a paper rocket around a film canister, which is used as the engine. An antacid tablet and water are put into the canister, react to form carbon dioxide gas, and act as the pop rocket's propellant. With the lid snapped on, the continuous creation of gas causes pressure to build up until the lid pops off, sending the rocket into the air. The pop rockets demonstrate Newton's third law of motion: for every action, there is an equal and opposite reaction.
