A decorative lampshade includes a frame defining an inner space and including a plurality of interconnected ribs surrounding the inner space; and a plurality of transparent filaments disposed around the inner space and attached randomly to the ribs. Each of the transparent filaments bridges at least two adjacent ones of the ribs so as to form a plurality of openings between each two adjacent ones of the ribs.

A water globe includes a programmable, multi-color, fiber optic display that can be synchronized with an audio source. The fiber optic bundle sits in a well where the first end of the bundle receives illumination from a three-color LED and the second end of the optical fibers is held in place by an inner top in such a way that the surface of the inner top produces an attractive changeable, multi-color display.

A technique plate in accordance with the present invention has a dimension ring, two clamping disks and a sleeve. The dimension ring has an internal edge, two side surfaces and a clamping protrusion. The clamping protrusion is formed on and protrudes from the internal surface. The clamping disks are mounted on and clamp the clamping protrusion of the dimension ring. Therefore, compared to a conventional technique plate of the same diameter, the technique plate of the present invention is lighter, so the distance between a bar of a barbell and the ground is higher to prevent beginner's injury.

A lamp string includes bulb mounting units arranged electrically in series with each other, and light-emitting units, each provided with two conductive leads. Each bulb mounting unit includes: a receptacle formed with angularly displaced first and second inner shoulders, the first inner shoulder having a shorter depth than the second inner shoulder from a top open end of the receptacle; a mounting seat mounted in the receptacle and including a flange formed with an axially extending protrusion, the flange having a portion seated on the first inner shoulder, the axially extending protrusion being seated on the second inner shoulder; and first and second conductive contacts contacting the leads of a respective light-emitting unit.

A holiday ornament is attachable to a relatively soft candle in such a fashion that it is firmly held to the candle until the candle burns down far enough to permit the ornament to fall off. A metal strip is welded to the back of the ornament. The two opposite ends of the strip are bent upwardly, away from the soldered portion and disposed at an angle of approximately 10-15° so that, when pushed into the candle, the soft wax exerts a force on the two pins in order to keep it in place during normal use. The structure of the pins keeps the ornament in the vertical position until the candle has burned down at least half way, at which point the ornament falls off for lack of support. Thereafter, the ornament can be removed and placed on a holiday item, such as a Christmas Tree, wreath, etc.

A low vibration and noise reduction exercise mat unit has a buffer plate and multiple protruding portions. The buffer plate has a board, multiple male buckles, and multiple female buckles. The board is quadrilateral and has a bottom, a recess, and a flange. The recess is formed on a bottom surface of the board. The flange is formed around the recess. The multiple protruding portions are disposed at spaced intervals in the recess of the board. The multiple protruding portions protrude downwardly from an inner top surface of the recess of the board. The buffer plate and the multiple protruding portions are made of natural rubber, will not affect the human body, and are stable in quality. The male buckles and female buckles can enhance the connecting strength between the mat units.

A method of making a rubber barbell weight with as least on colored rubber belt has acts of providing at least one annular colored rubber belt, providing a mold, placing the at least one annular colored rubber belt in the mold, placing rubber raw materials in the mold, heating and pressing the mold and releasing the mold. The mold has two middle molds. Each middle mold has at least one recess formed radially in an inside wall of the mold. The annular colored rubber belt is placed into the recesses of the middle molds. The rubber raw materials are placed into the mold. Because top and bottom flanges of each recess of the middle mold limit the annular colored rubber belt only fusing with adjacent rubber raw materials, an outside surface of the annular colored rubber belt does not mix with the color of the rubber raw materials.

A decorative lighting device includes: a light-emitting unit; a holding unit which includes an inner surrounding wall that has an outer wall surface, an outer surrounding wall that has a surrounding engaging surface spaced apart from the outer wall surface with a surrounding clearance, and an annular connecting wall that attaches the outer surrounding wall to the outer wall surface to form a surrounding abutment surface confronting the surrounding clearance; and a light-transmissive housing which includes an annular neck portion that terminates at an annular edge, that has inner and outer annular surfaces, and that is configured such that once the annular edge is brought to abut against the surrounding abutment surface, the outer annular surface is engaged with the surrounding engaging surface, while the inner annular surface is spaced apart from the outer wall surface to thereby cut off creepage of intruding extraneous water into the inner surrounding wall.
