Step 1: What You Need
All you need to make this Bundle-O-Fun is
A. igniter (lantern lighter, Piezo Electric Igniter, or Grill Igniter)
B. 4" PVC clean out plug
C. 4" PVC fitting clean out adapter
D. 4" PVC coupling
E. 4" x 24" PVC pipe
F. 2" x 4" PVC increaser reducer
G. 2" x 48" PVC pipe
H. PVC cleaner, primer, & cement
I. Without these all would fail you need potatoes
J. Hair spray (aerosol)
You will also need these tools. A drill, Handsaw, and File.
Step 2: Now Do It!(I Know You Can!)
Drill a hole for the lantern lighter in the middle of pipe E and then install the lighter with its included hardware. These lighters are very compact and use flint to produce a strong spark. You can find them in the camping section of large department stores.
With the file, sharpen the circumference of pipe G. This makes shoving the potato in easier because the pipe will cut off the excess potato.
Step 3: "Yerr" Done!!!
i. Find a very large, open area to launch the gun. Or do whatever the heck you want.(Just try not to do anything stupid.)
ii. Load a potato. Use a stick or rod to plunge it most of the way down the barrel.
iii. Spray the hair spray (make sure it’s flammable) into the fat end of the gun. If you use too little the potato won’t go far; too much and it won’t launch at all because there isn’t enough oxygen in the chamber.
iv. Quickly screw on the plug (part B).
v. Hold the gun at your side, aiming in a safe direction. Give the lighter a quick flick, as if you’re snapping your fingers.
(also if anything were to go wrong, (i.e BIG kick back) you would want to keep any "valued" or "precious" body parts you would like to keep, get them out of the way.
