Gotta Hate Them Rocket Eating Trees :/

Our LAST attempt
with hopes of a ten second, cone staying on, parachute deploying, not getting on the roof rocket launch.

So, we were only able to do one launch because our rocket got stuck in the tree right in front of Midkiff... We started with a rocket with no parachute, water ruined fins, and lost nose cone. So, we made new fins and covered them with tape for reinforcement, we made a slightly large nose cone, and a new parachute out of a thinner plastic bag. We kept the six fish line strings for the parachute and the small piece of Play-Doh for the nose cone for a weight to help the cone to fall off. We used a larger nose cone in and Play-Doh in hopes that the nose cone would fall off easier when in the air for the parachute to deploy. We then used a lighter parachute to make it easier to catch the wind and open up. With this, we got a flight of about 7.6 seconds, which is pretty good for having remade everything in about 30 minutes. However, the fact it landed in the tree didn't help for our hopes of making the 10 seconds. If we did get another chance we would've found a more fitting way of folding the parachute so that the strings didn't tangle and so the bag would open up easily. Everything else seemed great because the aerodynamics of the rocket allowed it to shoot up high, the nose cone came off and stayed attached, and the rocket arched. Nevertheless, our parachute came out, but it didn't deploy fully probably because of the strings becoming entangled. Although we made 10 seconds once, it was too bad we weren't able to make it this time. Our rocket was still able to make it till the final launch, which was pretty awesome and we definitely had a fun time getting it this far :).

  3. Aww :( Good job guys. After monday, Ian and I tried to stay as far away from Midkiff as possible. I think if it wasn't for the tree, you would've made the time limit because your parachute would've had enough time to deploy properly. Maybe you could build another rocket to get the 10 second time limit another time this week :) if not, I think you guys still did better than some of the other groups :)

  4. Your guys rocket was very well thought out but the same case goes for everyone because the weather just absolutely sucked. And at 7 seconds you guys were just very close
