In our first attempt we filled the 2L bottle with water about 1/4 of the way full. After that we set up the launch site by putting the base into the ground, plugging the soda bottle, clamping the bottle upside down to the base, and finally attaching the air tube to the air pump. After pumping the air up to 50 psi in the soda bottle we then pulled the string to release the clamp and the bottle launched. I thought it was a good first launch because the bottle went straight up and landed safely. I think we were able to make a successful launch and now we're ready to add onto our rocket for a longer flight time. We're thinking about adding fins, a cone, and wings in order to extend the flight.
