The magician displays a small, empty cabinet to the audience. The cabinet has open sides, which can be seen through. When the lid of the cabinet is lifted, instantly and visibly it fills with a silk handkerchief or a sponge ball! For added oomph, the magician can place a square of flash paper inside the cabinet. Upon ignition, the paper is seen to visibly transform into the ball, silk, etc.
Made entirely of powder-coated metal for a lifetime of use. Large in size, with a small load capacity (several sponges, silks, etc.)
