Step 8Ammo, Firing, and Results
For ammo, my favorite City Ammo is a wet sock. I take a calf-high, white cotton athletic sock, roll it up tight, and bind it together with zip-ties. Take this sock and soak it in water until saturated. This will produce a good projectile that won't do too much damage to fences, houses, people, etc. The water gives it enough weight to travel a fair distance, and everybody has lots of 'lost' socks at home. Of course, wet ammo is much more fun in the summer, as they sometimes spray water around at your friends.
Filling your barrel with water right from the garden hose is also quite fun, good in squirt-gun fights. Of course, try to keep the barrel mostly upright.
In the first picture, you can see my brother preparing to ram a wet sock projectile down the 1.5" barrel. We used the other barrel, the 0.5" barrel, as a ram-rod, although nearly anything long and thin will work.
Video One: Here, my brother and I are shooting one of the aforementioned wet socks using the 1.5" barrel. We are standing behind our garage and shooting into the neighbors yard. The sock landed by the small shrub that you can see in the video. The cannon was pressurized to about 40 psi.
Video Two: Here, my brother and I are shooting small plastic beads with the 0.5" barrel. Since the beads were smaller than the inside diameter of the barrel, and didn't form an air-tight fit, we used a small piece of paper towel as wadding. You can see the paper towel floating down to the ground, a few feet past the barrel. The beads all landed near the same shrub the sock landed by.
Bolts: My brother discovered that a small bolt fit nicely in the 0.5" barrel. He shot it into a piece of plywood. The bolt drove through the wood about 0.25 inches. Please don't shoot bolts at people or houses.

paintballs come in different sizes but the best to easily fit is the .50" paintballs

My brother made a cannon similar to this. Instead of the pressure guage on the cannon, it is on the compressed air pump we use to fill the chamber. Put it up to 80-90 psi, load a rock w/ a foam sabo, and fire clear through a THICK piece of plywood. I wouldn't reccomend going to 80-90 psi unless you've taken the proper precautions in construction. But it is funny as hell!
