Step 5: Tape balloon in place

IMG_6309.JPG
Wrap a piece of tape around the PVC to hold the balloon in place. That's it!

Just drop a projectile into the bottom of the balloon through the PVC, pinch the item with your fingers, pull it back, aim, and let it go.

Just don't shoot anybody's eye out, okay?

This looks like a great time! I wonder what would happen if you used bigger diameter pipe and bigger balloons... Tennis ball cannon methinks.

Is there a way to make it more silenced?

I don't think so. It's pretty quiet as is.
