Abstract: A lamp illuminates a waterfall from behind as a liquid cascades down the outside of a housing into a basin. From the basin, the liquid flows through a cavity in the housing, behind a body and through a pump, through an outflow line, through a cap with filter, and into a liquid retainer at the top of the body. The liquid retainer overflows, allowing the liquid to cascade down the outside of the body and back into the basin for recirculation. The enclosure comprises alternating opaque and translucent bands. A light source within the cavity behind the enclosure illuminates an inside surface of the body with the translucent bands transmitting light through the cascading liquid, producing an appealing visual effect.

Abstract: A table lamp having an ornamental liquid container movably connected to a main body thereof, so that the ornamental liquid container tends to swing, rotate and/or turn upside-down under an external force applied on the ornamental liquid container. At least one type of liquid, such as a dual-liquid or a magma-like liquid, and floating ornaments are contained in the ornamental liquid container. The liquid and floating ornaments tend to create unique, changeful and dynamic scenes when the ornamental liquid container is moved by the external force applied on it. The ornamental liquid container therefore gives the table lamp novel appearances and additional decorative effect.

Abstract: An ornamental liquid color box includes stationary clear containers fixedly mounted on a cover of a seat. Propellers are provided on the seat to propel liquid colors flowing into the seat to liquid passages that are led to upper storing zones of the containers. Liquid colors sent to the upper storing zones then moves into narrowed middle display zones to form flattened and irregular drips before reaching lower storing zones of the containers and entering the seat again to complete a cycle of movement of the liquid colors in the liquid color box. The whole liquid color box need not be manually or mechanically turned to maintain continuous circulation of the liquid colors in the liquid color box. The propellers are driven to rotate by driving means that may be coil windings or a combination of a motor and magnet-loaded driving and driven gear wheels. No leakproof means, such as shaft seals, are required for the liquid color box.

Abstract: The invention is a water powered wheeled toy which is constrained to travel in circular orbits. A coupling at the top of a stationary pylon connects a water hose to a swivel coupling. A hose is connected from the swivel coupling to a balance point on a wheeled vehicle. Water is delivered from the hose to the wheeled vehicle where it is delivered to a turbine wheel which drives the wheeled vehicle. The vehicle thus travels in a constrained circular orbit.

Abstract: A water activity toy with a channel for a stream of water which floats a vessel on the stream. A paddle wheel moves through the water to move the stream. The paddle wheel includes a plurality of blades all on axle stub portions at supports at opposite sides of the channel. Each blade could be above the channel when a vessel floats by. The blade is curved downward around an axis extending from the base edge to the free edge of the blade so that with two oppositely directed blades both oriented to extend along the channel, the middle of the blade would be higher off the water in the channel than the regions of the blades at the axle portions. Each blade also has a cutout at its base edge so that if the blade were oriented upright, the base edge of the blade would be higher off the water in the channel toward the middle of the blade than at the axle portions.

Abstract: A water activity toy including a main channel portion for a stream of water, and the channel having a siding which distends one side of the channel. A gate or wall is pivotally supported on a pivot post in the main channel and is operable between an upstream-downstream orientation, which directs the main water flow through the main channel portion for floating a vessel through the main channel portion and an orientation transverse to the main channel portion which diverts the main water flow into the siding and floats the vessel into the siding. The gate is also operable to the upstream-downstream orientation with the vessel in the siding for retaining the vessel in the siding. The siding may be a harbor for the vessel. An impeller moves the water in a stream through the main channel.

Abstract: A toy floats on the water surface of a pool. A hydraulic jet propulsion unit is connected to the bottom face of the toy. The propulsion unit includes a rigid tubular member with a straight central portion, a forward right angle elbow and a rear exhaust tube extending at an acute angle to the central portion. The forward elbow is connected by a flexible hose tether to a water source. Thee hose is anchored at an intermediate point to the pool bottom. The rigid tubular member is rotatably mounted in a housing so that it is free to rotate about the long axis of its straight portion. Water forced through the rigid tubular member is ejected from the exhaust tube, forcing the toy forward. When the elbow is vertical, the toy moves straight forward. When the elbow is rotated to the left or right by the pull of the tether, the exhaust tube also rotates to left or right causing the exhaust jet to leave the stern at an angle, turning the toy as it moves forward.

Abstract: A fishing lure of minimal buoyancy, having a propeller-driven tail that wriggles realistically in response to motion of the lure through the water. Minimal buoyancy is assured by the use of small diameter wire in the construction of the body of the lure, and mounting arms provided on upper and lower parts of the body of the lure permit the addition of weights, floats, or control surfaces so that the lure will run at a desired depth, such as during trolling. The fish hook is preferably disposed in the tail of the lure, which tail is readily detachable from the body of the lure when a fish is caught. Versatility of the lure is assured by the tail and the propeller being readily exchangeable for devices of a different configuration, such as when operating conditions, or the fish being sought, warrant a change.
