An illusion creating device comprises a support structure having a support edge encircling an aperture and a flat element. An elastic membrane is supported on the support edge and is stretched over the flat element to a degree wherein a supporting segment of the membrane underlies a portion of the element and supports it. The flat element is viewable through the membrane so as to appear to be disposed on top of the membrane. Pressing the stretched membrane over the flat element causes the element to be released from the membrane, thereby creating the illusion that the flat element passed through the membrane.
A coin-magic device has a stand on top of which a first coin receiving surface is formed. The device further comprises a tray that is used as placed on the first coin receiving surface to hide the coin. The tray has also a coin receiving surface that is referred to as a second coin receiving surface. Two more coins are placed on the second coin receiving surface. In addition, the device comprises a casing. When the casing is fitted onto the tray and stand, the tray is turned from the first coin receiving surface to the inner wall of the casing and appears as if it were the inner wall of the casing. Therefore, the two coins on the second coin receiving surface of the tray are hidden between the tray and the casing, and the coin on the first coin receiving surface will appear in stead. As the casing and tray are lowered along the stand while looking into the casing through a prism provided in an opening of a frame provided on top of the casing, the optical property of the prism will provide an illusion that the single coin on the first coin receiving surface look like two pieces. As the casing and tray are further lowered, the two coin images will approach each other and finally overlap each other. Thus, the audience will have an illusion that two coins have been halved to a single piece.
