Awesome!

A few buddies and I made a potato gun with PVC pipe using hairspray as a propellant in the dorms last year. We got it to shoot about 200 feet. Good times

PS. Potatoes explode when shot at doors at close range. Also, to make a potato shot gun simply substitute peanuts as ammunition.

Starting fluid works best!

Well, you should watch the movie in my post....

But regarding the potato cannon, real men use acetylene. That's how I roll.

You know, nobody ever uses pencils in the office anymore. They'd never miss them. Now if I could use string to tie the trigger to the door knob.........I'd never have to worry about the company "open door policy" anymore

What's always great, is to use those "industrial size" rubber bands...those ones that pull like a compound bow, and attatch those to a doorknob with a pencil in it in such a way, that when the mark opens the door, it snaps the pencil across the back of their hand hard enough to break the pencil in half.

Back in college, we used to boobie trap the dorm rooms of those who forgot to lock up like that....usually a few hours later when you hear this bloodcurdling scream of pain, you knew the mark came home.

The coolest are "mini" potato guns... sort of like a pistol. What I'm trying to work on now is a way to "auto-load" the hairspray... Like mount the can on top or bottom and make it so that I simply have to depress it to inject the fuel. There has to be a way to feed it in without having to screw and unscrew the chamber cap each time...

Yeh we got pretty good at getting the cap back on pretty quick, but having a way to get it in there without it would be awesome. I love my toys

I've found that by using a 18" triangular engineers/architectual scale and a heavy duty rubber band you can shoot an Xacto knife almost 30 feet with reasonable accuracy. Pencils are only good for about 10 feet or less.

We used to do something similar with five or six soup cans and tennis balls with lighter fluid. You would duct tape the open cans together (all except the bottom), stuff a doused tennis ball with lighter fluid inside, and light the bottom of the can (you'd poke a hole in the bottom to stick a match in). There goes this flaming tennis ball hundreds of feet in the air.

Hey Clint, what about something like this:

All you would need to do is have a "drop flap" to cover the spray tip so the flames wouldn't ignite the can.

As somebody who works with piping and chemicals all day, I've had plenty of time perfecting the potatoe gun. We had the long range mortor, the more accurate bazooka, some smaller grenade launchers and a SUPER GUN (basketball).

Oh, and yes we tried acetylene. Worked fine till we got the oxygen mixure too high. Just melts the interior and cracks the chamber.

Now for the fuel adder port, we used a 1/4" ball valve tapped into the side of the expansion chamber. Open the valve and squirt in the juice. On the other side you use the spark ignitor for a Coleman lantern for the trigger. A small spark plug can be uses for the field artillery (cantaloupes and honeydews mellons). The most important thing you have to remember is use schedule 80 PVC (and heavy-duty grey glue) or for the SUPER GUN use C900/C905 PVC (must use restraining joints).

Your tax dollars at work!

Geez, and I wasted all those hours building amps!

Let's just hope all this info doesn't fall into the wrong hands...
