FIRST LAUNCH

Today in class we launched our rockets in class for the first time. We filled our bottles with about 500mL of water and did absolutely nothing to the bottle. With this launch we saw that the rocket once fired is our of control. This is most likely because of the bad aerodynamics of the bottle. This can be fixed. Some ideas we have came up with is first of all making a bigger rocket. This longer rocket with fins and a nose cone will allow it to fly straiter which would allow it to go higher. Well thats what we think will happen. Another modification we will make is we will try experimenting with more water in our bottle. In this video you can see how our rocket launches and hooks to the left. If this arch is straitened, the distance and time of the bottle can be increased.

Design

So my idea for the design is to make a point to make it aerodynamic, and wings to help stabilize the rocket while its in the air. I want to put in a parachute, but im not sure what is the best way to do that yet. The parachute will help to slow the rocket down which the purpose of this rocket is to stay in the air for ten seconds. Im thinking cardboard for all of the extra materials, because it is light and cheap. But, If we put in the nose cone, fins and parachute, the rocket should hold up in the air for more than ten seconds. As of right now though, my bottle has no materials attached and is naked 0.o
