Our first rocket was just a normal 2 liter bottle without any modifications added to it. As we learned from our reference website and other groups we were able to decide upon what types of modifications we would add to our second rocket. On our second launch we added a paper nose to the top of our rocket as well three large fins, which we glued to the side of the bottle. This design had little success but on our third launch we were required to add a parachute to our rockets. When we designed our rocket for the third launch we scrapped the fins and instead just added the paper nose cone with a plastic bag in it that would act as a parachute. The parachute was attached to the bottle with plastic strips we made out of the plastic bags that acted as the rigging for our parachute. On the fourth launch we added six small fins to our rocket along with a larger nose cone that had the same type of plastic bag we used in launch 3 but instead of using the plastic strips for our rigging we used yarn. As we thought we had perfected our design we added more length to our rocket by adding half of another 2 liter bottle on top. This rocket also used six small fins, a nose cone, a parachute, and once again we changed our rigging from yarn to regular string. This design was very promising for success but unfortunately it fell very short from our expectations. In the future we need to make sure that we use a clean bottle because when we glued the fins to our rocket they fell off during the launch.
