Rip apart an old, dry pen and it becomes a weapon of choice (or at least it holds them.)
Step 1: Rip the Pen Out of the Tube.
Take your hand (or teeth) and grip the end of the pen. Take your free hand and hold the tube. Rip them apart. Should pop out and look something like this.
Step 2: Fill Tube With Airsoft Pellets
Now all you have to do is fill the pen with airsoft pellets. A regular sized pen should hold 20 pellets. Now take this ammo into battle!
Step 3: *TRY THIS*
Make the holder out of a clear pen, so you can actually see the bullets and how many are left in the container.
