There is disclosed a gas discharge display device comprised of microspheres containing ionizable gas, photons from the gas discharge within a microsphere exciting a phosphor such that the phosphor emits wavelengths in the visible andor invisible spectrum. An assembly manifold is attached to the first and second fuel cell stacks. A conduit extends transversely through the cap and opened on opposed sides of a circumference of the body of the cap, the conduit being in fluid communication with the spout and having a passage in fluid communication with the cavity. The invention furthermore relates to a method for improving the confidentiality of a user input. The sheet of material can be sized to be carried in a purse or wallet or hung on a microphone stand and the like for easy access.
