Today we did two launches. On the first launch we timed our bottle rocket with no attachments. Sadly it flew into the tree which helped it stay above the ground for eight seconds. On the next attempt We added on four wings and made the rocket longer with a second bottle. The wings helped to create a little drag which stabilized the bottle while in the air. The extra bottle lowered the center of pressure which also helped to keep the bottle going straight up instead of at an angle which would decrease time in air. The modifications with the bottle rocket helped to keep it up right for most of the launch. We lost two of the wings during mid-flight. So hopefully if we glue them on better and add a nose cone with a parachute, it will help to keep the rocket in the air for ten seconds. Kory and I will have to figure out a way to keep the parachute in until the top of the launch, where hopefully the parachute will deploy.
