ABSTRACT:
A liquid ball capable of providing dynamic view. The liquid ball includes a ball portion containing liquid and a magnet-containing ornament, and a base portion supporting the ball portion and defining an inner space for accommodating a driving mechanism. The driving mechanism includes a main spring barrel or a motor and a gearset. Two gears of the gearset mesh with toothed surfaces of two decorative ring members on an outer surface of the base portion and rotate the ring members. A central gear of the gearset closely below the ball portion is connected at a top end of its rotary shaft with a radially extending arm member. Two magnets are attached to two ends of the arm member, with different magnetic poles at their top side. When the arm member rotates along with the gearset, the two magnets produce a changeable magnetic field to revolve and rotate the magnet-containing ornament in the liquid inside the ball portion.
