Things You'll Need
Instructions
Leave the box intact. Cut out the flaps from the top and the bottom. Run the edge of the scissors around each end of the box to leave an open top and bottom.
Reinforce the rest of the box with duct tape. Wrap duct tape around each of the box's corners from end to end. Also wrap all of the exposed edges. Repeat the process several times to increase strength and thickness.
Cover the box in rubber cement or another hardening agent. Leave it to dry overnight before touching it.
Dig a large dowel rod or wooden post into the ground. Stick it in until it is sturdy enough to support the box.
Use the duct tape to mount the box on the post. Wrap the duct tape through the box and back around the post several times.
Test the hoop out with a ball. Lighter balls should work well. Make any changes necessary to the hoop and add reinforcement duct tape for strength.
