Today is March 15, 2011 and was the first day that we have launched our bottle rocket. There were no difficulties with setting up the equipment or launching the rocket it. We were able to launch the rocket on our first try. The design of our rocket was your simple 2-liter bottle with no adjustments added to it. We wanted to test the 2-liter bottle first to see the airtime results and make adjustments from there on so that we would have a longer airtime. The airtime was 5.23 seconds. The bottle rocket shot up into the air but than landed southwest of the launch pad if north is facing the Akahi stairs. To improve the airtime we would add fins and even a parachute to help the rocket stay in the air longer. This experiment involves Newton’s third law for every action force, there is an equal and opposite reaction. Since the bottle rocket had force making the rocket go into the air the opposite reaction would be the forces of gravity pushing the rocket back to the ground.
