The idea is ancient; holy men, both pagan and Christian, were reputed to have had the power of becoming light at will and of moving through the air. It is a favorite manifestation in séances. It is also a popular conjuring trick, the illusion being produced by clever mechanical or lighting arrangements or other means. levitation [‚lev·ə′tā·shən] (mining engineering) In froth flotation, raising of particles in a froth to the surface of the pulp, to facilitate separation of selected minerals in the froth.
