Rocket Launch!

Last week my class and I worked on a rocket. This was not your ordinary rocket. Our rocket was made out of a 2-liter bottle, a tennis or rubber ball, cardboard, and a lot of tape and glue! We chose to make our rocket's aesthetics look like the Saturn 5 Rocket. To do this, we painted the base of our rocket (the 2-liter bottle) white and the fins (cardboard) were black. We also had to paint some black stripes on it in some places, then, we added the NASA signs on it as well as the American flag. Then we had to construct it. As you know, a 2-liter bottle is not, well, aerodynamic. So we used a funnel to put on the top (after we painted it white). To attach all of the pieces we had to use hot glue. Once that was done, we had to construct a parachute. We did not want our rocket to break when it hits the ground! So, to complete the parachute, we used a very strong trash bag and then shaped it to look like a hexagon. We then used string to attach it to the rocket. When we tested the parachute, it worked very efficiently. Now it was time to launch our rocket. To launch the rocket we used a pump to put pressure into the bottle rocket. We decided to use 100 psi (pressure per square inch). Once it reached 100 psi, blast off! Our rocket when pretty high, however, the parachute did not work! So, when the rocket hit the ground, it shattered. Even though the parachute did not deploy, out rocket did very good. Overall, it was a great experience!
