Day 4: March 7, 2011

With the difficulties of day three behind us and the help of a little wind and prayer, you could say we did pretty good. As ten minuets dropped to two, our hope dissipated as each launch failed. Our first launch stayed in the air for 3.62 seconds, followed with a launch of 3.94 seconds, and succeed with a 2.93 second launch. As time kept running away, we gave up hope. With two minuets left to launch, we quickly filled up our bottle and started pumping air into the rocket. When we pulled the string, it was truly an act of God. The cone fell of and our parachute deployed. The wind blew the parachute father and farther up. Just when we thought it was going to fall down, another gust of wind came. That happened three different times. Our total time was 17.83S. Our modifications that we made to the rocket were a new cone, a larger parachute, and a different material for our fins. We made our cone out of laminated hard stock. We used a garbage bag instead of grocery bag. We also made our fins out of a folder. We need to find a different way to attach our cone to our bottle. We could change our fins to add more drag.
