Things You'll Need:
- 2 feet of 4 inch PVC pipe
- 4 feet of 2 inch PVC pipe
- 4 inch to 2 inch PVC reducer
- 4 inch sewer plug
- Electric barbeque starter
- 4 Screws
- Epoxy Glue
- Can of Aerosol Hairspray
- bag of medium-large potatoes
-
Step 1
Using a file, sharpen one end of the four foot length of PVC. This will be the end of the barrel and will serve to shave the potato down to the correct size when you cram it in the end of the gun.
-
Step 2
For this set of potato gun instructions, you will need four screws. Insert them at the other end of the barren, about three inches from the end. They should be evenly spaced. This will prevent the potato from sliding into the combustion chamber which will describe in the next step of the potato gun instructions.
-
Step 3
Glue the reducer to the two foot PVC pipe using the epoxy glue. Glue the Sewer Plug to the other end. The sewer plug looks like a big cap, but it has a plug in the end of it with a square head which you can unscrew.
-
Step 4
Drill two holes in the center of the 2 Foot section of PVC pipe and install the electric barbeque starter. The potato gun instructions can’t exactly tell you how to do this because they are all a little different, so follow the manufacturers’ instructions and use your head.
-
Step 5
Glue the barrel onto the combustion chamber using the epoxy glue. Now you are done with the potato gun instructions. Let it dry and its time to try it out.
-
Step 6
Cram a potato in the end and push it down to the screws using a broom handle.
-
Step 7
Unscrew the plug and spray a modest burst of hairspray. This may take trial and error because too much and it will not ignite and too little and it won’t have enough juice to launch the potato.
-
Step 8
Put the cap back on, aim and fire.
