How does a bottle rocket work?
A launcher powered by a hand bicycle pump or small compressor fills a plastic pop bottle rocket with compressed air. When the bottle is released from the launcher, air escapes the bottle. As the bottle pushes out the air, the air pushes the bottle upwards (Newton’s Third Law of Motion).
How big should a parachute be for a bottle rocket?

How do you make an effective bottle rocket?
This is fairly simple and safe. The basic idea is to put water into a bottle with some air. Put the bottle upside down with some type of stopper and then increase the air pressure. When you release the stopper, the air pushes the water out the bottom.
How do you keep a bottle rocket in the air longer?
Tips
- Use higher pressures.
- Keep weight to a minimum.
- Increase rocket volume.
- Streamline the body of the rocket to reduce drag.
- Use a launch tube on the launcher.
- Use the right amount of water.
