In this 'ible i'll show you how to create a simple but powerfull spud gun. (a.k.a. the taser totter a.k.a the tater tosser a.k.a. the potatoe cannon a.k.a. the spud-zooka)
However, instead of the commonly found and more dangerous combustion based spud gun, we'll be building a pneumatic spud gun. (It fires using compressed air) The gun's design and inner workings are actually very simple. Using an air compressor, a chamber is filled with air. This air is held in the chamber by a valve. When the valve opens quickly (in a fraction of a second) an enormous amount of pressure is released onto the projectile, forcing it down the barrel, and finally, out of the gun into your neighbor's window.
Before we begin, I nor Instructables will hold responsibility over what you do with the information you are about to recieve. If this form of pneumatics is illegal in your area you will be held accountable for your actions. Even if it is not illegal for you, you are accountable for yourself. This project is not reccomended for small children as this is dangerous. once again, I NOR INSTRUCTABLES WILL BE HELD ACCOUNTABLE FOR YOUR ACTIONS.
Head to the next step to find out what materials you'll need.
Step 1: What you'll need

- two 2" 90 degree elbow joints
- two 2" "t" joints
- 2" cleanout plug
- 2" single flange quarter turn ball valve
- a tank valve (MP3229) 1/8" male NPT threads
- a 115 psi 1/4" NPT tank safety valve (pressure relief valve)
- teflon tape
-any form of liquid soap for leak testing (kaboom works well)
- 1/8" NPT pipe tap
-1/4" NPt pipe tap
- 0.344 drill
- 0.437 drill
- a saw
-pvc primer and cement
-a dremel tool with a relatively large sanding bit
