Launch #4

This is our third launch day and it was a success. For the third day we made a lot of modifications. The first thing that we added to our rocket was that we added three fins to the outside of the rocket. Before we put the fins on, we measured the the bottles circumference and then made precise markings to which each fin would be equidistant to each other. Then we hot-glued each fin to the bottle and then the fins were finished. The next thing we did is that we cut off the top of our rocket and left a big gap on the top for a parachute. We cut off the top so that the parachute could fit inside, but also so that during its time in the air, the top would come off and then the parachute would burst out of the rocket and pop open for the  parachute to be in effect. We cut a trash  bag and cut it into the shape of a parachute. Then  we added string to the parachute to connect to the bottle. The idea behind our awesome parachute came from the process of how a toy-soldier parachute works.
