Introduction: Lil BANG Pneumatic Mini Cannon

A simple and cheap compressed air gun made from house hold items. Shoots VERY far.

I got bored one day and decided to make one. I already had the supplies so what the heck.

I AM NOT RESPONSIBLE FOR ANYTHING THAT IS BROKEN OR KILLED WITH THIS GUN. NEVER SHOOT AT PEOPLE OR ANIMALS, OR SHOOT DEADLY PROJECTILES LIKE NAILS OUT OF THIS GUN.

This is my first Instructable so please go easy.

Step 1: Get Out the Materials!!!

Materials:

Engine cleaner air compressor attachment
Empty refrigerant can
2 Female couplers
1 Male coupler
1 Threaded connector
Tape
You don't need a cell phone (lol)

Tools:

Pliers
Saw (optional

Step 2: Put It Together!!!

First pull off the tip of the engine cleaner with the pliers or cut it off. There may be a smaller tube inside if so, pull it out or unscrew it (they are all different). Once that is done, wrap the spot where the pipe connects to the handle with tape (you could glue it if you want). Once that is done, screw the male coupler onto the refrigerant can. connect the 2 together and you have a gun.

Step 3: The Tank Filler/Compressor Thing!!

This is the easy part, all you have to do is screw in the 2 male couplers into the threaded coupler.
Look at the Pictures if you need help (lol)

Step 4: Filling!!!

Put the piece that you just made into the piece on the bottle and the identical piece on the compressor.
fill for 30 seconds or until you feel that it is good (you can use a gauge, I just didn't have the right one). WARNING DO NOT exceed 170 psi max because the bottle will explode and the shrapnel will kill you!

sorry I couldn't flip the picture.

Step 5: Firing!!!

Put whatever fits in the barrel and press the button.

(my camera died right before I pulled the trigger so no picture. video coming soon ( if my video camera doesn't die)).

where can you get an air compresser and how much will it cost?

Pretty much any hardware store, even walmart, it depends what you want. If you want a little pancake compressor then it might cost like $50 or you could get a super bad one that cost $900. Whatever you want

i saw an air compressor in a japanese refurbished shop (pcpark japan) for 2,500 pesos (around 50 dollars)
P.S. it was the badass kind

you can get a compressor from many places, like Kmart, home depot, lowes, harbor freight, and sears. The small ones start from $80, to the big ones that can cost up to $800 bucks. A good one will cost you around 1-200 bucks. thats what mine was around

I'm using a bigger barrel so I was thinking a AAA bateries

they fit in this barrel, but they dont go too far, mabye 20 feet, I use Little plastic bullet shaped things I found in my garage, they fly like 150 feet.

wrap some electrical tape or tissue around it for a tight fit

Maybe dead lithium batteries would go further?
