pneumatic potato gun i made

[Pat McCarthy]

I built an air powered potato gun last fall.
From experience, I've found the best way to fit a potato to the barrel.

• Cut a potato in half down the center, into two bullet shaped halfs.
• Place one half, cut side down, on the ground and force the PVC pipe over the half to cut the potato to the perfect fit to your barrel.
• If you need to, take a stick and push out the shaped half, and reinsert it into the barrel so that the slightly rounded end is pointing at what you want to shoot at. (This makes for a more stable shot)

Try this, if this doesn't work, some pictures of your rig would be helpful for more advice.
