Window displays of puzzling nature usually draw crowds. A lighted globe lying on its side in full view, yet apparently not connected to any source of electricity, could easily be arranged as a window display, deceiving the closest observer. A mirror, or window glass, backed with some opaque material, should be used for the foundation of the device. For the display lamp, it is best to use a 25 or 40-watt tungsten, as these will lie flatter on the glass than the larger sizes, and the deception will not be as easily discovered. The place where the brass cap of the lamp touches the glass should be marked and a small hole drilled through to the wire connecting the tungsten filament to the plug on the top of the lamp. At any suitable place, a hole should be drilled in the glass plate, no larger than is necessary, to permit two small cotton-covered magnet wires to pass through. One of the wires should be looped, passed through the hole in the cap and hooked onto the bare wire connecting with the plug on top of lamp. The other wire should be fastened to the brass cap, near the drilled hole, after which the lamp may be placed in position and the two wires connected to a source of electricity. If proper care has been taken and no crosses oc- cur, the lamp will light, and if the display is placed in the proper surroundings, it will prove very deceiving. To protect against a fuse blow-out from a short circuit, it is advisable to run another lamp in series with the display lamp, as shown. - Contributed by Clyde W. Epps, Mineola, Tex.
