NOTE this project may be dangerous and I am not responsible for any damage caused by it
Step 1: The Bow
find a bow stick and cut off all the knots in the wood,then make an arrow rest by cutting a piece of pvc pipe1 1/2 inches long then tape it on the bow right over the spot you want the handle to be on.next find a screw just like the one in the second picture and screw that over the arrow rest. The screw will be the sight. then tape the spot you want the handle to be on.
Step 2: The String
this part I actually got from an instructable called the 15 minute pvc bow by basement hacker
So you use two bungee cords , put both hooks on the same side and tape them to one end of the bow,do the same thing to the other end. Now tie para cord to connect the bungee cords
Step 3: Enjoy
now you can make your own arrow and enjoy shooting outside,but remember be careful !!!
Oh and here is a pic of the screw
