A decorative device enabling ornaments to revolve on a rotary screen
inside a crystal ball amidst fluttering, shiny disc snowflakes, which
uses a device structured from a motor mechanism, a gear mechanism, a
rotary screen mechanism and a crystal ball so that when a motor drives
and rotates transmission gears of the gear mechanism, apart from using
mutually repelling of two double-sided magnets to drive and rotate a
magnet impeller wheel, and thereby cause whirling of water and fluttering
of shiny disc snowflakes within the crystal ball, moreover, a main
transmission shaft is also driven, thereby driving and causing a PVC
(polyvinyl chloride) rotary screen to revolve.
