Last class, we all went outside to Konia field to practice launching our water bottle rockets. They weren't exactly rockets, because everybody still had the basic 2L soda bottle, unmodified. We did this to get used to launching, and to prepare us for future launches so we know what to do. We filled our bottles with 500 mL of water (for now) and set it up on the launch pads after Mr. Blake showed us what to do. After setting it up, we pumped air into the bottle to create pressure that would propel our rocket in the air. This would work according to Newton's 3rd law of motion: For every action, theres an equal and opposite reaction. As the pressurized air would exit the bottle upon launching, the bottle would propel in the opposite direction. It would also continue to travel after all the water has left due to inertia.
