Abstract
Abstract A phosphoresent condom is provided with a bead of phosphoresent liquid located at front end between a pair of sheaths that are one inside the other so that when placed over a regular condom, pressure will brake the bead allowing the phosphoresent liquid to travel and glow between the total length of the sheaths. In another embodiment, the phosphoresent condom is fabricated out of a center layer of colored phosphor material between two sheaths of latex rubber so as to isolate the phosphor material when placed upon a penis.
