Can you calculate how high they went, ignoring effects of wind resistance? We shot them at a 30 degree angle from verticle, and got a maximum distance of 115 meters. Also, try checking to see if the 30 degree angle is correct by calculating the angle from the distance of 120 meters and the hangtime of the rocket that you measure in the video. What is the potential energy from pressure? What is the potential energy at its maximum height? Does these potential energies match up?
