Abstract: A transparent yo-yo includes two rotatable yo-yo halves (10) two half-spherical, rotatable yo-yo halves (10) each having a valve (12); two caps (13) each fastened in the valve (12); two sealing plates (40) sealingly engaged with the yo-yo halves (10) respectively; two spaced anchoring members (50); and an axle (20) comprising a threaded shank (21) and a nut (22); wherein the threaded shank (21) is adapted to dispose in both the anchoring members (50) and threadedly secure to the nut (22) in the other anchoring member (50) to fasten the axle (20) and the anchoring members (50) together; and wherein the anchoring members (50) are complimentarily secured to the sealing plates (40) respectively.

Abstract: A pet covering (e.g., egg) includes a fragile shell including an upper portion, a mated lower portion and a plurality of apertures on lower portion; and a baby pet formed of water absorbing material and disposed in the shell. Pouring water into an open container contained the pet covering will cause water to enter into the shell through the apertures to cause the baby pet to develop by absorbing water until a predetermined pet (e.g., an animal-like figure or a doll) is formed by breaking the shell. Preferably, the shell is formed of a mixture of plastic and calcium carbonate. Preferably, the baby pet is formed of a mixture of acrylic-based water-absorbent resin and ethylene vinyl acetate copolymer.

Abstract: Articles of play comprising a racket having a handle portion and a hitting portion integrally formed together, the hitting portion including a hollow annular frame body and a hitting surface which is firmly secured in and highly tensioned by the hollow annular frame body so that a high tension hitting surface with a resonating sound box inside the hollow annular frame body and the handle portion is thus formed when a ball member is hit by the tension hitting surface, a sound like the durm beat is produced.
