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)
