Launching+A+Rocket+With+Dry+Ice

Matt G   Cary Academy ** ABSTRACT  ** The purpose of the experiment was to see if the time it takes a piece of dry ice to sublimate and the time it takes for a model rocket’s engine to reach its peak line up and see if the dry ice can shoot the top of the rocket off using pressure opposed to what would happen if the rocket didn’t have the dry ice. It is hypothesized that if a piece dry ice is put in the nozzle of a model rocket, by the time the model rocket gets to its peak, the nozzle will have shot off. A piece of dry ice was put in the film canister. The time it took to explode was recorded and was repeated. Then an engine was clamped down and ignited. The time it was ignited for was recorded and was repeated. Then a piece of dry ice was put in a rocket and the rocket was launched. The results were recorded and the control was launched and recorded. The rocket with dry ice shot over the middle school. It flew over the Fine Arts building and landed on the grassy field. In the middle of its flight, the rocket seemed to have a small explosion, but the rocket kept going. The explosion must have separated the nose cone and the body, because they came down separately. The rocket kept flying even without its nose cone. The control flew directly up, and the engine blast shot the top off, which was expected.
