1. First our group thought of the angle of the barrel that would propel the nerf ball a descent distance.
2. Then we sketched what the cannon would look like, keeping the angle of the barrel in mind.
3. We then marked on the tennis ball tubes where we were going to cut. On one of the tubes we marked a 45 degree angle on the side to refer to when cutting.
4. Our team then taped the tubes together following the guidelines of our sketch and marks on the tubes.
5. Finally we put our initials on our cannon and turned it into our teacher.
