Went to tap plastics and got an acrylic tube 1" od 18" long. They have stock 1" round discs we glued on the ends to close it up. Then we used a drill bit to make a bunch of holes. Then a dremel with a cutting blade to cut the slot to catch the flow.
We used suction cups to hang it that has a wire attached to the tube.
