ABSTRACT:
A crystal ball water sealing structure includes a hollow, transparent, spherical water container having a neck and an inside annular groove within the neck, a rubber stopper plugged into the neck of the spherical water container to seal the spherical water container in a water tight condition, the rubber stopper having an outward flange forced into engagement with the inside annular groove in the neck of the spherical water container and an inside annular groove, and a spring element mounted in the inside annular groove in the rubber stopper, the spring element imparting an outward pressure to the rubber stopper, causing the rubber stopper to expand radially and to engage with the periphery of the neck of the spherical water container so as to prevent a water leakage.
