Instructions: The Glow Golf Ball is great for playing on the course or practicing in your backyard at night. The instructions below explain how to properly use the glow in the dark golf ball: 1) Activate the Glow Stick Insert by bending once. The glow stick will take a few minutes to completely activate. 2) Near the hole at one end of the ball you will see a small "S". This is the Small end of the hole. Insert the glow stick into the opposite end of the glowing night golf ball. 3) Before each stroke re-position the glow golf ball so that the club head strikes the ball parallel to the stick (play winter rules). 4) To keep the glow golf ball properly balanced, check to make sure the stick in centered within the ball before each stroke. 5) To replace the stick use a tee or similar instrument to push the old glow stick out. Push from the Small end of the hole marked with an "S" toward the large end. 6) Each player should mark their glowing night golf ball with a felt pen.
