Snipe your friends with this little compressed-air gun! Despite her size, this little beast packs a punch! Sorry for the bad quality, I took the pictures with my webcam (The pink wall is due to the light reflecting on my red bed).
Remember: whenever using an object that shoots projectiles, DO NOT AIM AT SOMEONE'S FACE! I will not be responsible if anyone is hurt.
Step 1: Requirements
To make it, you need:
-A reynolds pen
-A reynolds Eraser/Rewriter pen
-X-acto knife (Any sharp blade will do)
-Isolating tape (Or whatever it's called)
-A Bic mechanical pen
Step 2: Making the air chamber
Use your knife to cut off the edges of the eraser. Remove the ink and "magical" erasing solution tubes, and use a stick/brush to push the little cap hiding in the pen (keep it!)
Step 3: Making the barrel
Cut the end of the reynold pen (keep approx. 1 cm of white plastic).
Step 4: Assembling the gun
Insert the barrel in the air chamber, put the cap in the other side. To fire, make a small spitball (put paper in your mouth for a few seconds and shape it into a ball), put it in the barrel (make sure air cannot pass by pushing the ball with a toothpick), and push the little cap with a stick/brush.
Tip: If the cap can't move easily, use soap.
Right now, it looks nothing like a rifle, but it works.Go to the next step for customisation.
Step 5: Customisation
Remember the optional items at the beginning? Time to use them.
Wrap the air chamber and the barrel with tape.
Step 6: Finding a rifle to replicate
Use google for ideas. I'm making a M24.
Step 7: Making a (fake) scope
Take your mechanical pen. Disassemble it and keep the smaller tube (see picture), cut it, and wrap it with tape. Stick it to the body of the gun with tape (I used carboard squares as mounts).
Step 8: Adding details
Now add small details like stocks, bipods... To make a stock, make a cardboard shape of what it should look like, repeat until it's thick enough, tape the pieces together, and then tape it on the rifle.
