One or two rows of straight flow nozzles can be installed on the holders with same distance between each nozzle and connected with wave rod. But the nozzles can swing free. With the underwater motor's power, each row of nozzles can longitudinally swing with the same angle, like rows of silver hair swinging in the wind. If eight to ten fire and water nozzles are installed in the pool, the picture would be spectacular and brilliant in color with a silver dragon dancing. Depending on the users' demand, on-site designs can be done to different pools.
