Due to the fact that my previous pen gunhttp://www.instructables.com/id/EH4ZKYAVSDEXCFGF1S/
was confiscated because it didnt look real at all and i got caught, i had to make a new one with no givaways. You can see it below. Perfectly normal, well, it looks
that way. This easy instructable will tell you how to make your own classroom-war-waging device.
Step 1: Materials
Look at the pics.
Step 2: Salvaging pen parts
Take apart the clickable pens. You will only need a few of the parts from the clickable pens: 1 black tip, and both springs.
Step 3: Get the black tip ready.
This step will tell you how to prepare the black tip for your pen gun. It's an important part, so do it right.
First, take your drill and 5/32 general purpose bit and enlargen the tip of the black tip by drilling in through the back, like the main pic. Second, you have to file(dremel is easier) down the little edges that stick out around the middle that would keep the tip from going into the pen tubeand file those down, alond with the area that actuall should go into the tube, so that the black tip can be pushed in completely into the tube. Note: Make sure you file or dremel it down enough so it can be pushed in but it should be big enough to keep itself in, in other words, dont let it slide out. you also dont want it to be hard hard to get in. Test for this often while filing or dremeling. The final thing should look like the second picture.
Step 4: Get normal pen ready.
This step will prepare your other pen to be made into the gun. First, pull on the tip of the pen, and the ink should come out. Using the coathanger wire, push out the end cap on the other side of the pen. Throw the little piece you just pushed out of the tube away.too get the ink ready, dribble super glue down the space between the ink tub and the inside of the tip. The pic shows it well.Wait for it to dry completely.
