the object is a bracket to hold an empty soda can. the user punches a hole in the side of the can near the bottom then inserts the can into the bracket. the bracket can then be mounted on a board at either a flat angle or upright. using a bucket or other container an aquarium pump is used w/ plastic tubing to carry water up to the top piece. then the water either goes in the side hole & out the end opening, these can then waterfall into more cans/brackets. water can also go into the end opening and out the side hole. the final piece needs to drain back into the bucket/container. brackets also have screw/nail holes on the bottom/side for mounting to the board.
