The Handkerchief Pedestal is a classic prop for the production of a handkerchief in a clear glass tumbler. The effect can be found detailed in many magic text books.
In effect a clear glass is placed on a skeleton pedestal. The glass is covered with an empty cylinder, (which could be examined if you wished). When the cylinder is lifted away a silk (which has been previously vanished) appears inside the clear glass tumbler.
Besides handkerchiefs, this can be used for a sponge ball routine, or even a “Bill Tube” type of effect, where a borrowed signed bill vanishes from a spectator’s hand, and appears in the empty glass.
