i have to make a hairspray powered one for science and if theres a video of how to make one or etc itd be great if you guys could hook me up
 
dude those things are seriously so sweet. My friends dads friend(if that makes sense) let us use his they take out windows like nothing but i know a little about them...

umm he used an ignitor for the grill to lite it with...and just pvc gun part, and thats about all i know sorry
 
i have one i made.the one thing is DO NOT use pvs pipe.pcs pipe is really thin and has a really good chance of exploding after a few shots. use the black abs pipe and it works wonders.just get a tube about 3 feet long in the front glue a chamber on the back of it with a lid, drill a hole and securly glue on a b-b-q sparker and voile,you have yourself a gun
 
its simple

use a 4 inch by 2 foot section of pvc for the combustion chamber

put a screwable endcap on that

use a pvc tapering part to atact the barrel

taper from 4 inch to 3 inch and 3 inch to 2 inch

put a barrel on and you have a gun

the barrel should be 4 to 6 feet

use some skrews and a bbq lighter for the ignition

its fun
 
wait does anyone actually have a video? because someones saying use PVC while anothers saying dont use PVC im confused
 
yea, we made one from pvc for science in middle school and it was great. except we used propane and an air compressor

i apologize for the awful quality (yay for ms paint)

the things that look like "put" really say "pvc"

overall just keep it really simple and itll work
 
dude fuck geese if you just so much as touch them in Wisconsin, its a 400$ fine. and they harass you and nip at you when youre golfing. i hate those things
 
no its not you tard...pick up a piece of black abs pipe and a piece of pvc, i guarantee the abs is at least double the thickness as the pvc
 
i have one its 6 feet. 4foot barrel 2 inch diameter and a cumbustion chamber of 2 feet with diameter of 4 inches. dont use hairspray it doesnt go good. use starting fluid for cars it has ether in it. that shit flys. ive got mine to go 700+ yards.
 
use pvc it works fine..just steal/buy a bunch of grill ignitors because they usually break after a while...and sharpen the end of the barrel so you just push the potato in and it will cut off what doesnt fit and be the perfect size
 
i had one and it was sick as fuck and then the cops rolled where we were shooting it and made us break it up. 50 bills down the drain.
 
haha we where shooting mine at a house under construction so it was just the wood up so far. We where shooting from quite a ways off and we thought the pottatoes where exploading when they hit the house. Anyways we went up and looked at it and the house was full of holes. Much more powerful than we expected. We then left imediately
 
i got a sweet, made out of pvc, its got a 4 foot barel made out of 2inch pvc and the combustion chamber is made out of 3 inch pvc, then i glued a screw on pvc cap so you can open it and spray in hairspray then close it off and click the barbecue ignitor. make sure evrything is tightly glued, believe me they have power. Mine shoots a good 200 feet EASY and with alot of power, thats just with the gun pointed flat, if you tilt it up itl fly halph a kilomiter (did it at my lake and went into the middel of a small bay)

 
Thats like exactly what I did. Ours had a flexible joint at the barrel so we could aim it a little more precisely. I'd also recommend getting a screw cap end for the firing chamber, it makes it a whole lot easier to clean and fuel. Make sure to drill a screw through the barrel so potatoes dont fall into the chamber. Also, let the glue dry, my friend almost took his face off after test firing the BBQ lighter in its newly created home. Good luck, and dont let the threads on the cap catch fire!
