  • Patent number: 6568107
    Abstract: This invention deals with an ornamental display receptacle which has a transparent envelope which contains a clear fluid and a particulate such as artificial snow or leaves or the like, which is suspendable in the fluid upon agitation, thus simulating falling snow, leaves or the like, and which includes a power driven agitator which will maintain the particulate in suspension so long as the motor is in the ON. The particulate will be at rest in the display receptacle when the motor driven agitator is not operating. An ornament, such as a house or an individual or the like, will be positioned in the receptacle to enhance the simulation of activity around the ornamental object.
