it pushes the rocket into the air to make it go higher.
Pressure builds up, and when it is released it forces the rocket up.
THe ideal amount is 50% air pressure and 50% water. SHoot from 4-6 bar. I got mine to 92 meters

If you have leaks in a water bottle rocket, the pressure will quickly escape along with the water and the rocket won't be able to reach as high an altitude as a rocket without leaks.
If you are in Science Olympiad, a bottle rocket is a modified 2 liter bottle designed to stay up in the air longer than its competitors. Another type of bottle rocket is a type of firework you place in a bottle to make it launch.
Bottle Rocket was created in 1994.
The duration of Bottle Rocket is 1.53 hours.
You can make a soda bottle rocket.
Bottle Rocket was released on 02/21/1996.
The pressure pushes in all directions save one, downward (toward the nozzle). All the forces are balanced except one: the push on the top of the bottle.
The 'operator' fills the bottle with water, then pumps air into it - creating pressure. When the stopper is released, the air pressure forces the water out of the narrow opening in the bottle's neck - creating a stream powerful enough to launch the rocket into the air.
The Production Budget for Message in a Bottle was $30,000,000.
