Physics Water Bottle Rocket Competition
Event Description: Teams of two or three people will build a water bottle rocket that will stay in the air for a maximum amount of time.
- Rockets are to be constructed from a 2-liter soda bottle.
- The soda bottle must remain intact.
- Additional materials such as fins, nose cones, parachutes, etc. are permitted.
- The bottle will have water and 40 psi of compressed air put into it. When the pressure is released, the rocket flies.
