For the first two rockets my partner and I built paper rockets, some things we learned was that we had to make our rockets sturdy, perfectly sealed and light.
For our final rocket we originally wanted to build a paper rocket because we knew how the mechanics worked and how to keep the egg from breaking. Although we knew how to make everything and knew how it would work we finally decided to create a bottled rocket because how would we learn failure from doing the same things we already knew how to build.
Both of my other partners built bottled rockets for the second launch, one on them cut the bottle which was not successful during the launch. We decided that for our final rocket we wouldn’t cut the bottle, so instead we used two bottles and attached them together. Our failures and successes from previous rockets helped us build and create our final rocket.
Our final rocket consisted of ; four sturdy fins, 1 and a half 2 liter bottles, and a parachute. Some people used parachutes to keep the egg from cracking. We thought that was a great feature to incorporate. During the second launch the fins that didn't work as well were the thinner, less sturdy and the really small ones/really big ones. For our nose cone we wanted it to come flying off so we made it thin and wide, so the air would push it off. At first we had no idea how to keep out egg from cracking. Then we went around and asked other groups what they did. We eventually got an idea from Tim and created a small cradle with padding in it and attached a bag for a parachute. Our rocket’s average height was 156 feet and the distance was 76 feet.
