This intructable will show you how to make a great quality pen shooter for free. This is a very fun 'toy', if you will. **I am not responsible for what you do with this, or any injuries caused**

Step 1: Materials

99% of you should have these items at home.

-1, or more rubberbands of choice. I used 2 because they are small.
-electrical tape, duct tape, or any other tape with good stick.
-a pen, one with the ink cartridge as a simple tube. (pens such as Bic, are not great because they have that plastic cartridge holder at the end).

Step 2: Taping the Rubberband

Take apart the pen. Throw away the cap and the end cap. All you should have left is a plastic tube and the ink cartridge.

Place the rubberband(s) onto the tube with a 2:3 ratio to the tube.

Get a piece of tape about 3 inches long. Tape the middle of the rubberband to the tube, but do so that the tap is more toward the end of the rubberband.(look at pic)

Finish taping up the rubberband, tightly. Look at the picture for tips on how to tape it well.

Step 3: Taping the Rest(If You Used More Than 1 Rubberband)

This step will depend on if you used more than 1 rubberband.

-Stretch the rubberband alot to give yourself room to tape and to find the middle section.
-take a small piece of tape(about 1 inch or so) and tape the tip of the rubberband.

Step 4: FINISHED.

Now that your done, go shoot something! Here is a video of shooting a soda can. I have had a shot go through both sides of the can before. Also, try experimenting with different rubberbands, pens, and tape. There are also shooters i have made- look at pics
