Tennis Ball Launcher

As a group we were assigned a project to come up with a device that can launch a tennis ball. We had the stipulations of only being able to spend $8, and the dimensions were 18x18x20. We had a two week assigned period to work on this project and make an adequate tennis ball launcher. We had to make a launcher that could shoot a tennis ball a 25 feet distance, and hit a target that was 2 feet above the ground. It took us many attempts to find the right way to build this machine, and trial and error was our main way of testing. Throughout the process of building this we learned how to work better as a team and what each person could bring to the project. We finished the project and ended up only hitting the target two times out of six, but the project in itself was a learning experience that was quite enjoyable.
