Bottle Rocket Entry #2 "First Launch"

Noah and I have finally caught up with the rest of the class. Our group may be behind in posting on our blog, but as soon as we have another chance to launch our new rocket, we will begin to upload video footage. Noah and I skipped the first two launches, and went straight to building our rocket with fins, a cone, and a parachute. We designed our rocket with two sets of fins to keep it from spinning out of control when launched. Our parachute also was a last minute design, which looked like it wouldn't work, but for all of you who saw our first launch during the beginning of the first activity period would know how "beast" our rocket is. Our group did not tape our first launch, but to summarize how awesome it was; our rocket shot up to an estimated height of 200-300 feet, and after falling for two seconds the parachute deployed successfully, and our rocket floated from above Konia field down to the road where the buses turn into Konia, and almost got caught in a tree. The estimated flight time was somewhere around 15-25 seconds. The specs on what we did to make our rocket launch higher are:

Water- about 1 liter, or half the bottle
Air Pressure- We kept pumping until air began to leak from the hose, and we got tired

 After a few modifications to the broken fins, and a half-ass 6th period paint job, our rocket is ready to be launched again next week.
