This is my first instructable so I am going to show you how to do something easy.
Step 1: Materials
All you will need for this is a papermate X-tend mechanical pencil and some scissors.
Step 2: Disassembling
Pull of the cap and unscrew the middle part.
Step 3: Assembling
Cut a line through the papermate logo on the middle part and screw it back on. Then put the cap on(don't push hard).
Step 4: Launching Mechanical Pencil!
To launch press on cap and watch it fly! If you're like me and think outside the box look at the picture below. To make it go farther click it while pretending to throw it.
