A novelty illusion device producing an illusion of a shimmering floating bubble having a transparent case, an illusion object disposed within the case, an electric motor for producing rotational force, a power circuit and power source for driving the motor, and a drive shaft for transferring rotational force from the motor to the illusion object. The drive shaft is rendered virtually invisible to an observer when the drive shaft is rotating by concealing the shaft within a groove formed in the casing. The illusion object is made of a plurality of mylar strips joined at both ends to form a cage structure. Additional circuits are included to vary the movement of the illusion periodically and in response to detected sounds. |
