Wonder rocket :O

The video goes on a bit, but his launch is flawless :O

This would've been a very ideal launch,

but this is just for kicks because everyone's rockets and launches were amazing :)

pretty sweet :]

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 :).

Launch day 2... 3/1/11

Today we added some modifications onto our bottle rocket. We attempted to add on fins, and a ghetto nose cone. We found out that our nose cone was not too great. When we make another one, we found out that we need to make it more aerodynamic for it to work. The fins that we added on helped a little. But we didnʻt get the angles and shape of the fins right. And also next time, we need secure the fins on better. Another modification we need to add on, is some weight. That will help the rocket fly straighter and hopefully better.

First Launch Attempt

In our first attempt we filled the 2L bottle with water about 1/4 of the way full. After that we set up the launch site by putting the base into the ground, plugging the soda bottle, clamping the bottle upside down to the base, and finally attaching the air tube to the air pump. After pumping the air up to 50 psi in the soda bottle we then pulled the string to release the clamp and the bottle launched. I thought it was a good first launch because the bottle went straight up and landed safely. I think we were able to make a successful launch and now we're ready to add onto our rocket for a longer flight time. We're thinking about adding fins, a cone, and wings in order to extend the flight.
