Step 1: Materials
As many Paper Clips as you want!
Step 2: The SlingShot
First hold the rubber band in between your middle finger and thumb as seen in the second picture
Next insert the paper clip into the slingshot, pull back, aim, and FIRE! as seen in the first picture
Step 3: The Belt
First measure a piece of duct tape around your waist.
Take another piece of duct tape equal length, and fold on the first piece, thus no sticky part remains.
Next take 2 smaller pieces of duct tape at equal length (This will be the pouch) and attach the 2 pieces, but leave some sticky part on the long side.
Attach the sticky side to the belt, so it is hanging down.
Attach some more duct tape to the side and stick.
Tweak if you need to in case it is not "pouch like"
Step 4: Ammo
you can use note cards, tacks, etc...
I keep my rubber band on my wrist, instead of having another pouch for rubber band...
