SCIENCE OLYMPIAD ROCKET BOTTLE EVENT

Students in Science Olympiad Building Events built their first bottle rocket and launched it. In bottle rocket category ,  participants design, construct and launch up to two rockets made from two empty plastic carbonated drink bottles, which hold 2 liter or less, to remain aloft for the maximum period of time possible. In the competition, the team may shoot two rockets off, each one only once. If a team only has one rocket, it must still only be shot off only once. The team may add any amount of water to the bottle. It is then set on the launcher and shot off at 60 psi. The time is recorded for each rocket to the nearest hundredth, and the two times are added up to create the team's final score.
