Abstract
An ornamental water ball is provided in a base with a musical box having a movement and a lower disc, and in a transparent shell fixed to a top of the base with a fan and a decorated upper disc above the fan. When the movement is rotated, it synchronously rotates the upper disc through meshing of a first small gear on the movement with a second large gear mounted on an axis that is located in the base and engaged with a spindle of the upper disc. The lower disc is mounted on the axis and quickly rotated through meshing of a second small gear formed at a lower center of the lower disc with a first large gear mounted on the movement, so as to magnetically rotate the fan, causing the fan to scatter a plurality of snowflake-shaped chips or metallic chips in the shell.
