Water Rocket Project

Water Rocket Project
This project was considered the final project and final grade in our physics class. Our project was to build a water rocket that will launch and keep a tennis ball in the air for 30 seconds. Our job was to build the rocket and keep the tennis ball in the air without it hitting the ground. Unfortunately it was a lot harder then it seemed. It took us about 4 trials before we were able to successfully keep the tennis ball in the air.
