Potato Cannon 2

I started construction of another potato cannon today. Dennis is having another party this Summer, and I obviously have to build a better cannon so I can compete. I cut off the barrel on cannon 1 to see what effect it would have on range, and the range was shorter. I'm going to start with a long barrel on cannon 2 and see if it's any different than the original cannon. Here are a few photos of the current state of cannon 2.
