2015 Rocket Building and Launch
By: Katelyn Petersen
The Background Research
Our rocket body will be made out of at least one 2 liter soda bottle and will have 3-4 fins made out of cardboard attached to it.
One question we had was what was the point of the fins. The fins help with the stability of the rocket when it is in flight. The fins can be made out of different material but cardboard was what we had decided to use. We also looked at what shapes of fins worked best and we chose to use a knife blade shaped fin.
For a one bottle bottle rocket you would need a 10-20 inch in diameter parachute. In order to make the parachute you would need a garbage bag, tape, and string. You would take the string and attach it to both you rocket body and parachute.
The nose cone should be made out of construction paper, pointed, and wrapped in tape. Also a small amount of weight should be added to the nose cone to balance out the front and back of the rocket.
- The rocket must be made out of at least one 2 liter bottle, and the bottle must have been from a carbonated drink (this is because the plastic is thicker, the plastic needs to be thicker so that when we pump it up it holds).
- There can't be metal parts anywhere on the rocket.
- You must make the parachute it can not be pre-made.
- The rocket parts are allowed to separate but must stay attached (no parts can fall to the ground during the flight).
- Completed rockets must weigh under 300g
