Preliminary Ideas and Construction

For our cannon, we originally planned to cut one of the tennis ball cans in half, then cut a hole in one of the halves, and fitting the other tennis ball can through the hole and using the half that we cut as a 'support platform'. This idea did not work, as the tennis ball can half was too flimsy and could not support the longer can. We fixed this problem by turning the half can sideways, and then using the bottom of on of the cans for support, as pictured below:



So far, our design and construction has been running pretty smooth! I hope our cannon works.
