A method for appreciating water balls using a water balls appreciation device, including a water balls discharge device and a light irradiation device, the method including: discharging the water balls, using the water balls discharge device, from tips of a plurality of nozzles, disposed at predetermined intervals in the lateral direction, by applying vibration to flowing water, the discharged water balls falling downwardly and in substantially a vertical plane; irradiating the water balls, using a light irradiation device, with light, the light irradiation device comprising a high-speed projector having a refresh rate of 300 Hz or more; and projecting a continuous screen of the projector in the water balls in the vertical plane regarded as a virtual screen by properly using a frame displaying a screen or an image and a frame not displaying a screen, so that a blinking duty is 20% or less, whereby the water balls are visually appreciated in the projected area. Then, by changing the timing of light emission for passing light through the image, it is possible to appreciate the movement of the water balls that changes in various manners.

In one aspect, this disclosure is related to a universal decorative water feature for use in potted plants. The decorative water feature, in the form of a fountain, is provided as a singular standalone device provided in an assembly. The water feature includes a bucket having sidewalls defining an interior space configured to hold water provide structure for the placement and attachment of additional components. Accordingly, the bucket upper side includes a lip for the placement of a screen cover, generally including a plurality of apertures to allow for the flow of water from an exterior of the screen cover to the interior of the bucket. The assembly including a submersible pump coupled to a power source, a valve handle that is accessible to a user at an exterior of the device, a water tube in communication with the valve handle, and at least one ornamental feature.

Disclosed is two-tier fountain with a continuous scupper. A continuous scupper is a 360-degree, unrestricted border (i.e., continuous), scupper in an upper basin that creates an inward flowing laminar sheet of fluid. A continuous scupper maintains a laminar flow for great distances so that the fluid falls in a circular cascade sheet. On reaching the lower basin, the fluid creates a limited amount of turbulence during entry and therefore a reduced splash. The continuous scupper may be circular, or may have simple to complex variations that create different forms of circular cascade sheets. The upper basin may be open to the atmosphere, or may be closed to create even more spectacular circular cascade sheets.
