Abstract: An electroluminescence visual device which works on the principle that when liquid mercury rollably moves along the smooth surface of glass is an partially evacuated atmosphere the mercury will emit flashes of light. This effect is intensified by the replacement of air with gaseous helium to increase the production of photons. The embodiments resulting take the form of flashing pendant earrings, flashing drumsticks, illuminated spheres and hemispheres and decorative blisters. The faster the relative motion of the mercury the more intense the light emitted. This light may be used for decorative purposes of for emergency illumination.
