When I was a kid, we made these out of used 35mm photo film canisters. Since film canisters have become quite scarce these days, this is an updated version that uses a piece of PVC instead.
You can discreetly turn many small items into high-velocity projectiles with this thing, like pencil erasers, airsoft BBs, and spit-soaked wads of paper.
Go ahead and make a few, and let me know what you think!
Step 1: Materials
- 1 inch of either 1" or 1 1/4" diameter PVC (I used 1 1/4")
- A party balloon
- Some tape (I used electrical tape)
Step 2: Sand the Edges of the PVC
Step 3: Cut Balloon in Half
Step 4: Position Balloon in PVC
Step 5: Tape Balloon in Place
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?
