For the pen and mechanical pencils, cheap, simple brands like Bic will work well.

Remove the cap from the pen, then unscrew the part of the pen that holds the ink from the outer plastic tube. {“smallUrl”:“https://www. wikihow. com/images/thumb/0/00/Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-2Bullet1. jpg/v4-460px-Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-2Bullet1. jpg”,“bigUrl”:"/images/thumb/0/00/Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-2Bullet1. jpg/aid35503-v4-728px-Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-2Bullet1. jpg",“smallWidth”:460,“smallHeight”:306,“bigWidth”:728,“bigHeight”:485,“licensing”:"<div class="mw-parser-output">

<br />\n</p></div>"} After you have done this, cut the closed end of the outer plastic tube so that you have a single tube with holes at both ends. {“smallUrl”:“https://www. wikihow. com/images/thumb/7/7b/Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-2Bullet2. jpg/v4-460px-Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-2Bullet2. jpg”,“bigUrl”:"/images/thumb/7/7b/Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-2Bullet2. jpg/aid35503-v4-728px-Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-2Bullet2. jpg",“smallWidth”:460,“smallHeight”:306,“bigWidth”:728,“bigHeight”:485,“licensing”:"<div class="mw-parser-output">

\n</p>

<br />\n</p></div>"}

Remove the grip from the mechanical pencil, and, if possible, unscrew the top (the part where the lead comes out). (You may need to cut this part off if it cannot be unscrewed. ) {“smallUrl”:“https://www. wikihow. com/images/thumb/d/d2/Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-3Bullet1. jpg/v4-460px-Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-3Bullet1. jpg”,“bigUrl”:"/images/thumb/d/d2/Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-3Bullet1. jpg/aid35503-v4-728px-Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-3Bullet1. jpg",“smallWidth”:460,“smallHeight”:306,“bigWidth”:728,“bigHeight”:485,“licensing”:"<div class="mw-parser-output">

\n</p>

<br />\n</p></div>"} Remove the eraser from the other end of the pencil and take out any lead that is inside. {“smallUrl”:“https://www. wikihow. com/images/thumb/e/ee/Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-3Bullet2. jpg/v4-460px-Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-3Bullet2. jpg”,“bigUrl”:"/images/thumb/e/ee/Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-3Bullet2. jpg/aid35503-v4-728px-Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-3Bullet2. jpg",“smallWidth”:460,“smallHeight”:306,“bigWidth”:728,“bigHeight”:485,“licensing”:"<div class="mw-parser-output">

<br />\n</p></div>"} The mechanical pencil is made up of 2 parts, the outer tube that you hold onto and the inner part that is made up the eraser holder and the thin inner tube that holds the lead. Cut the end of the outer tube so that you can remove the inner part (eraser holder and lead holder). This is the part that you will need. {“smallUrl”:“https://www. wikihow. com/images/thumb/d/d6/Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-3Bullet3. jpg/v4-460px-Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-3Bullet3. jpg”,“bigUrl”:"/images/thumb/d/d6/Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-3Bullet3. jpg/aid35503-v4-728px-Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-3Bullet3. jpg",“smallWidth”:460,“smallHeight”:306,“bigWidth”:728,“bigHeight”:485,“licensing”:"<div class="mw-parser-output">

\n</p>

<br />\n</p></div>"} You should now have only 2 components: the outer tube of the pen, and the inner part of the mechanical pencil (with the eraser holder, but without the eraser). {“smallUrl”:“https://www. wikihow. com/images/thumb/f/f4/Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-3Bullet4. jpg/v4-460px-Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-3Bullet4. jpg”,“bigUrl”:"/images/thumb/f/f4/Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-3Bullet4. jpg/aid35503-v4-728px-Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-3Bullet4. jpg",“smallWidth”:460,“smallHeight”:306,“bigWidth”:728,“bigHeight”:485,“licensing”:"<div class="mw-parser-output">

\n</p>

<br />\n</p></div>"}

At this time, you can also remove the plastic clip that is connected to the eraser holder. This is the part that would be on the outside of your breast pocket if you carried your pencil there.

Note: When you twist the rubber band around the tube, do not just wrap both sides of the rubber band around it, or else the rubber band will come unraveled. Rather, wrap one side of the rubber around so that the pen is actually inside the rubber band. Wrap this same side a couple of times, and then wrap both sides tightly around the whole tube. {“smallUrl”:“https://www. wikihow. com/images/thumb/2/24/Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-6Bullet1. jpg/v4-460px-Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-6Bullet1. jpg”,“bigUrl”:"/images/thumb/2/24/Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-6Bullet1. jpg/aid35503-v4-728px-Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-6Bullet1. jpg",“smallWidth”:460,“smallHeight”:306,“bigWidth”:728,“bigHeight”:485,“licensing”:"<div class="mw-parser-output">

<br />\n</p></div>"} Note: You can add more rubber bands for greater power. Follow the same method for wrapping subsequent rubber bands. {“smallUrl”:“https://www. wikihow. com/images/thumb/0/0a/Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-6Bullet2. jpg/v4-460px-Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-6Bullet2. jpg”,“bigUrl”:"/images/thumb/0/0a/Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-6Bullet2. jpg/aid35503-v4-728px-Make-a-BB-Gun-with-a-Mechanical-Pencil-Step-6Bullet2. jpg",“smallWidth”:460,“smallHeight”:306,“bigWidth”:728,“bigHeight”:485,“licensing”:"<div class="mw-parser-output">
