Day 1 Launch

In a nutshell our day 1 launch was pretty unsuccessful. We followed the directions and outcome consisted of me getting sprayed by the water (fuel) for the water bottle rocket.  We used a 2-liter Coke bottle as the body of our rocket.  For this first launch we did no modifications which means we used no fins, no parachutes, etc. Our first step was to fill 1/4 of the bottle with water to use as fuel.  The next step was to attach the bottle to the launcher.  I think something was wrong with our rocket launcher because at first our water bottle was not staying but we found a way that we thought the rocket was balanced.  Then we started to pump air into the bottle using a bicycle pump.  We needed it to reach 50 psi so that it would shoot into the air.  We started to pump but then the bottle started tilting and before you know it it shot sidewards and sprayed me.  I think tomorrow we have to clearly get a working launcher so the same thing doesnt happen again
