Today's Test Launch

Today, our rocket went 156 meters high, which was outstanding. We need to fix the nose cone, and then we can work on the final project for the rest of the class.

Day 3: Test Launch I and Reconstruction

Our rocket went about 72 m high, which was above average from what I've heard. Jacob, make sure to post pix on the blog if your phone will download the pix. Thanks.

Day 2: Planning and Construction

We had a good day today, but we spent a little too much time planning and talking about the rockets with some of the other groups. Tomorrow, we need to focus, and get the nose cone and parachute completed. I can bring in a 2 liter for the nose cone (more Dr. Pepper to drink!), and I don't think that we need anything else. Alex, if you think of anything to bring, comment on this post,

Day 1: Research

-3 fins
- About 33% Full is the best choice (with water)
-A parabolic cone is the best shape that produces the least amount drag
- For the most pressure, put pressure in, wait for it to cool, then put more pressure in.
-use this website to build a parachute: http://www.lnhs.org/hayhurst/rockets/
- a two or 3 liter bottle produces more thrust

We have not found a way for our fins, and we might use a glider
