1. Introduction


Introduction
A rocket obtains thrust from a rocket engine, allowing it to take off. Rocket engine exhaust is formed entirely from propellants carried within the rocket before use. Rocket engines work by action and reaction. Rocket engines push rockets forward simply by throwing their exhaust backwards extremely fast. Many rockets use chemicals to react with each other to generate the propelling force. We decided to work on this project as we found it very interesting on how the chemical reaction can launch a rocket into space. We plan to research on this form of launching a rocket but we plan to substitute the chemicals with baking soda and vinegar to build up pressure when they react with each other to thrust and propel the rocket to find out which ratio of baking soda to vinegar will launch the rocket the furthest. After looking through experiments that are similar to ours, we found that the best ratio of baking soda to vinegar is half the amount of baking soda to vinegar. This lead to our hypothesis being that the best ratio of baking soda to vinegar is 150 grams of baking soda to 200 milliliter of vinegar will launch the rocket the furthest.
