Disign for Rocket: Reese

My idea is, the more pointed the cone, the faster and smoother the rocket will fly.

Look at this fighter jet:

Do you see how everything is pointed? That is what makes it go fast, it can cut through air like a knife. That's what our rocket needs.


As for the whole design, the Rocket will have 4parts as of now. The basic body (smart water bottle that i bring in), another Smart water bottle which we will cut out the middle portion and will be used to hook the body to the cone.The cone, which i described at the top, and the four fins that i counted as one part. The fins will be thin and hard. So they supply maximum stability without adding to much weight to the rocket initially.

This is our design as of now,

~ Reese :)
