Measure your PVC segments for cutting. You will need three 24-inch sections, two 20-inch sections, and eight 12-inch sections.

Take two of the 12-inch sections and push them into the opposing ends of a T fitting. Cap the other two ends of the pipes.

Add the 20-inch section of pipe to the open end of the T section and another T section to the other end of the pipe. Make sure the new T is turned 90º from the direction the feet are running.

Add a 12-inch section of pipe to the T opposite the other pipe. At the end of this pipe add another T.

Place one more 12-inch section of pipe in line and cap it with an L fitting.

Repeat steps 2–5 to build the other half of ladder.

Join the two halves with the three 24-inch sections of pipe.

Drill 3/8″ holes in six golf balls. This is a hard step and is best done with a drill press by an adult. Using wiffle ball style balls can eliminate the need for drilling but are very light.

Cut three 24-inch sections of rope and thread a golf ball through each end. Tie off the ends.

The idea of the game is to throw the bolas at the ladder and try to catch them on a rung. For a better list of the rules, check out the official rules from laddergolf.com.
