 Normal fountain device can only make counter-swing or lateral swing on a round pipe. It is hardly to make centripetal inward or outward swing. The round-swing device researched by the company takes a mobile connector which can change swing direction to reach the result of centripetal swing. After installing, the round-swing fountain has graceful and changeable shapes just like Waltz dance or flying white swan. If adding numeric-controlled valves, water designs can change in thousand of ways in both running and swinging styles.
