Things You'll Need
Instructions
Select two thick trees or sturdy posts for your slingshot to be tied to.
Cut two lengths of stretchy tubing to whatever length you desire for the sides of the sling shot. The length of the material here determines how far back you will be able to pull your sling shot.
Tie a loop in all four ends of the two pieces of stretchy material.
Use the rope to tie one end of each of the pieces of the stretchy material to both trees or supports at a height that will be even with the hands of the person stretching back the sling shot.
Use the rope to attach the fabric pouch to the other ends of the stretch material. Cut holes in the fabric in order to loop the rope through.
Test the slingshot using a soft item such as a small stuffed animal before using any other projectile. Adjust the height of the stretchy material on the trees in order to correct your trajectory. Placing the tubing higher on the tree will cause the projectile to go higher, and placing the tubing lower will send the projectile on a lower trajectory.
