Double-Barrel Shotfun

It was just a spelling mistake in a humorous sub-thread, but it eventually became...

The Double-Barrel Shotfun - dealing out enjoyment at the pull of a trigger!

It's just what you needed - an overly-complex method of firing off two party-poppers at once.

(You can now accessorise your Shotfun with a dedicated bandolier!)

Step 1: Materials and tools

Picture of Materials and tools

You can modify this project to your needs, but this is what I used:
  • 4mm plywood sheet
  • Offcut of 6mm plywood
  • 32mm waste pipe
  • Industrial adhesive
  • Masking tape
  • 6mm dowel
  • Scrap corrugated card
The tool list is flexible - I used a laser cutter, but only because I could.  Similar results could be achieved with skilled use of traditional power and hand tools.
  • Lasercutter
  • Scrollsaw
  • Teaspoon
  • Files
  • Sander
  • Rubber mallet

Step 2: Prototyping

I first needed to prove that my idea worked.

This quick lash-up proved that a steady pull via a lever would work to fire a party popper.

Step 3: Lock, stock...

Once the concept was proven, I needed to stream-line it. I drew the laser cutting files in LaserCAM 2D, purely because it's the software my school bought with the laser cutter.  You can reproduce your own version in whatever software you prefer.

I designed most of it to be out of 4mm ply, but I decided that the section that would brace the poppers (the part that looks a liitle bit like a heart, and a little like a Batman logo) needed to be stronger, so I cut that out of 6mm plywood.

I took a screenshot of the design that you can use - the odd layout is to fit the piece of plywood I had close to hand.

The MCM file itself is in the zip folder with this step.  It's not huge, it just isn't recognised by the uploader if you leave it as an MCM.

having experimented with alternative loads for party poppers don't use blow pipe snaps they go off inside the party popper

That might make a good bang inside the barrels, though...

Thank you!
I love this build. I was thinking if you tied the strings of two poppers together you could just load, put the loop over the hammer, and be able to quickly fire and reload.

Great job, may have to make one myself!

Lol, my cousin and I bought a ton of these one time with the intent to turn them all into trip-wire traps that would blow flour or powdered sugar at the person who tripped it. We couldn't devise a way that gave us a repeated success, so we ended up storing them until we could revise our plan. Then we forgot about them. I had a few in my car and a friend asked if she could fire one off when my cousin got back into the front seat, so I said sure. I'm still finding powdered sugar in my car.

This Double barrel is a great idea i will use it for my Next Nurf shotfun :-)
Kiteman (author)  ToryDidIT11 months ago
Cool - post a picture when you do.
Another thought on ammo mod, try using colored glitter instead of flour for a more festive popper.
