Abstract: A revolving and self-rotating liquid-containing decoration comprising a freely shaped transparent container containing a liquid, a concave driving disk made of magnetic material and disposed in the liquid, a freely shaped decorative article disposed on the driving disk, a hollow base disposed under a smooth and plane bottom board of the container and a power assembly disposed in the base, wherein the power assembly drives the driving disk to revolve in the liquid contained in the container and when revolving, the driving disk and the decorative article simultaneously self-rotate due to velocity difference between a peripheral portion and a central portion of the driving disk.
