Structure of crystal ball providing dynamic phenomenon in the base
 The structure of crystal ball which can provide dynamic phenomenon in the base is disclosed. It includes a gear fixed on the driving axle of the music bell, the rotating pedestal on which the music bell is installed, and a controller engaged with the tenon of the chassis and located between the gear and the circumference of the rotating pedestal. When the driving axle of the music bell is rotated in a counterclockwise direction, the synchronous rotation of the rotating pedestal is limited by the controller. When the power of the spring of the music bell is released, the driving axle is limited by the controller to rotate in clockwise direction, then the rotating pedestal is driven to rotate in a counterclockwise direction by the music bell.
