In this tutorial, we learn how to make a bow and arrow from a ball point pen. First, you will take the top and bottom off of the pen. Then, use a knife to poke a hole in one side of the case until you reach the other side. Now, make small notches in the top of it so you can stick a rubber band on it. Do this on both sides and try to make it equal. Now, take the top of the pen and stick it in the little hole you made in the middle. Then, take the rubber band and stick it on. Then, shoot this and you are finished making your bow and arrow!
