What makes a good water bottle rocket?
The fins should be thin and tapered. Every surface on the rocket should be as smooth as possible. above). further back they are placed on the rocket, the further back the center of pressure (CP) will be thus increasing the stability of rocket flight.
What are the best materials for a water bottle rocket?
Using plastic soft drink bottles, cardboard or Styrofoam food trays, tape, and glue, small teams of students design and construct rockets. A simple assembly stand assists them in gluing fins on their rockets, and a nose cone is mounted on the top.
What is the best length for a bottle rocket?
Reaching 30 or 40 metres should be quite achievable, but distances beyond 100 m are possible with some careful design. The main problem with launching the rocket at an angle is that the rocket can no longer stand on its own feet, and if it is supported entirely by its nozzle, then it tends to flop over.

How to make a Rocket from a Plastic Bottle
- Tape pencils to the plastic bottle so that the flat end will touch the ground when the bottle is upside down.
- Pour vinegar into the bottle.
- Add the baking soda and quickly push in the cork.
- Flip the DIY bottle rocket upside down and step back before it shoots away!
What is the best fin size for bottle rocket?
4)Thinner fins (3/16” or less) are excellent for reducing the effects of drag, however, more effort is usually involved with securely attaching them to your water rocket. Thin fins must be very stiff once mounted to prevent movement during flight.
What is the best size for a fin on a bottle rocket?
Should a rocket have 3 or 4 fins?
Three fins are best when designing a high performance, low drag rocket. This allows interference drag (drag caused by interference of the airflow over the body and fins at the junction) to be reduced by 25 percent.
