The ornamental water light has an inner tube, an outer tube communicating with the inner tube and having therein water, a spiral pathway securely clamped between the inner tube and the outer tube and hollow balls movable inside the inner tube and between the inner tube and the outer tube. When the water light is operating, the bubbles from the bubble generator cause an upward current inside the inner tube and a resultant downward current in the space between the inner and outer tubes. Consequently, the hollow balls float upward in the inner tube and downward along the bottom face of the spiral pathway between the inner and outer tubes. The movement of the bubbles and hollow balls creates an ornamental and entertaining effect for the observer.
