I will be showing you how to make a Bic Pen gun that shoots 100+ feet and is smaller than your finger

See picture for materials.
only one pen is needed.

!I AM NOT RESPONSIBLE FOR ANY DAMAGE OR INJURY CAUSED! NEVER SHOOT AT THE FACE OR AND ANIMAL!

Step 1: Pen Gun

Take apart the pens. you will no longer need the cap or tube only the ink and tip of the tube. The ink will become ammo. take the pen tube tip off the ink. You will need both parts.

Step 2: Assembly

Take the rubber band and cut it once.

Step 3: Assembly

Put the rubber band on like this, with tape, be shure to pull tape tightly when rapring. Cut extra rubberband off.

Step 4: All Done!

Here you are!

When firing load the back of the pen ink through the barrel of the pen tub tip and pinch the rubber band on the ink, pull back and release..

Step 5: Ranges and Ammo

The Pen Gun will shoot about 100+ feet. Yes I know that sounds scary. When you use a flat rubber band (The best ones in my opinion), a long ink with fletchings (6 or 7 inches, get a long pen form dollar store or fair) it will shoot that far. I shot to about 3 house down from mine.
IF you want to shoot at friends for fun, I recommend to take tape and wrap a thick layer around the tip so it WON'T puncture skin.
