Abstract
An illusory liquid apparatus is disclosed which provides the illusion of an item appearing and disappearing. An illusory item is suspended in a translucent or opaque fluid, and raised and lowered to alternatively be visible at the top of the fluid, and hidden under the surface of the fluid. Also disclosed is a new means for moving the illusory item by means of magnetic attraction. A magnetic attractor is placed in the illusory item, and magnetic attraction is used to raise and lower the illusory item. Alternatively, liquid may be moved to alternatively cover a fixed illusory item and then reveal it, or a mechanical linkage used to raise and lower the illusory item in the liquid. A new configuration for an illusory liquid apparatus is also disclosed in which the completely sealed outer body and inner vessel of the illusory liquid apparatus avoids the use of complex mechanical linkages.
