Step 1: Materials

A pilot pen. (most pens work)

Step 2: Dismantling the Pen

To dismantle the pen start by unscrewing the top.
Now take the spring off of the top.
Next, push the part you click out along with the small piece that holds the actual pen part.
Now it should look something like this.

Step 3: Putting It Back Together

First, slide the part you click into the bottom part (just like before)
Afterwards, place 1 or 2 springs on top of it.
Next, put your small black piece that holds the pen on top.
Now, use the actual pen part to push it down past the groove, this loads the gun.
Here, put the actual pen part on top of it and hold it going at a 45 degree angle.

Step 4: You're Done!

Now you can fire it! Push the clicker until it shoots! If your parts come out just put them back and shoot it again! Just be sure to push the small black part back under the groove otherwise it wont shoot. And as simple as that you have yourself your own pen gun! A tip, if you put 2 springs it will have higher power. Im not responsible for any injuries. Please like and follow for more things DIY.
