Put it together: Duct-tape six rings to one another, then tape them to thicker (3 1/2-inch-wide) hollow pool noodle posts. Stand it upright: Hammer two 1/2-inch dowels (ours were 48 inches long) securely into the ground and slide the posts on top.
Join rings into a colorful target for noodle javelins, flying disks, soccer balls, and more. Stakes keep the target upright. Assign different point values to the rings for an extra challenge. You can also lay the station on the ground to play hopscotch or beanbag toss or to use it as part of an agility course.
