Introduction: Mechanical Pencil Launcher

In this instructable I will teach you an old trick to make a mechanical pencil into a pencil launcher. Every thing you need is already in the pencil .

NOTE: All pencils are different so the steps might be different. However in the end all you need is an outer tube, an inner tube, and a spring 

Step 1: Remove the Tip of the Pencil

Remove the tip of the pencil. It should either pull off or twist off. In this step I also removed all of the lead in the pencil.

Step 2: Break the "Lead Advancement System"

Your pencil should have a device on the newly exposed end, break it. You should be able to lay out all of the parts. You wont need the broken piece

Step 3: Putting It All Together

Put the spring in the Outer Tube, then slide the Inner Tube into the Outer Tube.

Step 4: Launching the Pencil

In order to launch you must grab the pencil and put your thumb on the Inner Tube. Then quickly slip your finger off. If done correctly your pencil should go flying
