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
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
- Rubber mallet
Step 2: Prototyping
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.
