After our rocket blasted into the air, I was shocked. As the seconds were counting down till take off, my teammates and I held our breath and took a couple steps back, prepared to watch our rocket burst into pieces. After poorly gluing out pressure chamber, having a leak, and repairing it by melting the plastic with a hot glue gun, smothering it in superglue, and several layers of hot pink duct tape for reassurance, our rocket took off into the atmosphere and flew pretty high and landed pretty hard. I think that our rocket actually flew because of our team’s awesome dynamic. With clear communication, sticking to our expected jobs, and our perseverance to make a rocket, team Ninja was a success.
Our first rocket flew, but we chose to make it better. 20 pounds lighter, and 4 days later, the Ninja was ready to fly. Each of the team members persevered and knocked the work out. Although the rocket had a rather hard landing at exhibition when the parachute didn't deploy, I was proud of our team. I think that if we had used more glue on the pressure chamber originally, had all the fins straight, and a better parachute deployment, our rocket would have defiantly won. The 2013 Rocket Launch Exhibition was a success. I learned a lot about rocket building, teamwork, and how to use failure to make something better.

Conclusion
The final step for our rocket project was to make all the calculations to find the maximum height and the hang time. To find the maximum height of the rocket, you use the equation: 53tan (angle)= the height in meters. Our equation was 53 tan 60=91.8m. You could compare this equation to a triangle with an unknown height. We then found our velocity, which was 26.8 m/s, afterwards we calculated different flight times. The first actual flight time was 26.8 m/s, our theoretical flight time was 8.6567 s. However, both of our flight times had some error from our friction device, our parachute, of 21%. Our parachute only deployed partially.

Rocket Journal Entries
Day 6, Journal Entry 1
Today our goal is to glue on our plexi glass fins onto our rocket. We are moving at a good speed.
Day 7 Journal Entry 2
Today we want to attach our nose cone to our parachute. Our rocket was test launched, and we have decided to start our rocket over. Our rocket is really heavy and spins and flies crooked.
Day 8 Journal Entry 3
Today we went back to the drawing board. We have decided to make a new rocket, with bottle fins, and a lot less glue so it is lighter. Today we will appoxy our pressure chamber.
Day 9 Journal Entry 4
Today we added the third bottle to my rocket. We named it the ninja.
Day 10 Journal Entry 5
Today we will paint our rocket because Grace isn’t here today and can't glue on the fins.
Day 11 Journal Entry 6
Today we will complete the nose cone and parachute. We are thinking we might use a tennis ball as a nose cone.
Day 12 Journal Entry 7
Today we had a rocket launch and found a hole in our pressure chamber.
Day 13 Entry 8
Today we need to repair the hole in our pressure chamber, with hot glue, super glue, and duct tape. We also will make a bigger parachute.
