This instructabule will tell you how to make a gun, that can literally shoot anything that can go in the barrel, this instructabules is also vary cheep and vary powerful.

Step 1: Finding the right sise

Picture of Finding the right sise
If you already don't know by other post of air guns, or penumic launchers, a air gun consists of a pvc air tank and a valve that allows the tank to flood the air in to the barrel launching the projectile.


Having a larger tank allows you to have a more powerful round while having a larger, and thinner barrel allows a more accurate shot, and a larger barrel, allowing more of a variety of things to launch.

down sides

having a large tank adds a lot of weight to the gun and will slow you down, a thinner berral is more likely to break under the pressure of the burst, and a larger barrel could not fire the round if to larg
and a longer barrel will definitely add coast to your maneuverability

For my gun i picked a extra large tank, a medium with barrel and a vary long barrel, my gun is vary power full and fairly accurate.

This is not spam, but a warning. PVC will fail suddenly after a while. This was band member that hurt badly by a T-Shirt launcher explosion.
