ABSTRACT:
A rotational color-liquid decoration including a base is set forth and a disk rotatably disposed on the base. The disk defines a closed space which is partitioned into multiple compartments in parallel with a surface of the disk. Each of these parallel compartments has a clear central area and an outer peripheral zone surrounding the central area. Colored liquid is sealed in each compartment to be carried by liquid collection units in the peripheral zone to a higher position when the disk is rotated. When the colored liquid in respective liquid collection unit reachs a certain position, it drips from an outlet of the liquid collection unit and passes the clear central area to be flattened into changing patterns in varying colors, serving as a dynamic decoration. A clock may be attached to a back side of the clear central area of the disk to enable the decoration to additionally function as a timepiece.
