Step 1: What materials you will need and putting the rubber bands on.
Take the first rubber band and put in on in this fashion with each end hoking on the blunt ends of the pen. Then take the second Rubber band and put it on in the same fashion but opposite of it so the rubber bands are like an X.
Step 2: Shooting the bow!
There are many ways of firing(play around with it) so post if you find a good way to fire it. If fired properly it can go over 20+ feet and 1 inch of cardboard!
