cardboard tubes + box = hours of fun! We pieced together TP and paper towel tubes. Used marbles. The kiddo loved it and even still pulls it out to roll the marbles into a dump truck. He wont' let me toss any cardboard tubes now.
A TIN FOIL RIVER * A River Runs through it. (in our front yard) * Camo and Bows * A trickle from the garden hose keeps the tin foil in place "as you build it" along the route the water flows! * Kids of all ages will enjoy on a hot day.
