A lamp showing movable floating ornaments is provided. The lamp mainly includes a lighting means for emitting light, and a closed clear container for containing and showing liquid and floating ornaments therein. A liquid-guiding means and a propeller are provided in a lower part of the container, and a driving means is provided below the container for turning the propeller. When the propeller is driven to turn, liquid flowing into the lower part of the container via the liquid-guiding means is continuously forced back into an upper part of the container via the liquid-guiding means at increased speed, so that the floating ornaments in the liquid in the container are brought to move around and create dynamic scenes in the container.
