Instructions
Spread the garbage bag out on a flat ground surface. Lay the tire on the bag. Make sure the bag covers the area underneath the tire to make a tetherball pole.
Mix the cement in the trough with water. Follow the manufacturer's directions to get the best results. Allow the cement to set for a 3 or 4 minutes, according to Momready. Pack the cement inside the tire, and make sure to fill it completely.
Place the tetherball pole in the middle of the tire. Use a level to make sure it's straight. Allow the cement to harden overnight. Attach the rope and the tetherball to the pole.
