In the late sixties, black light put things in a new perspective - adding a fluorescent glow to the room. White T-shirts and teeth would light up the room with their bright white glow. Black light would reveal secret symbols or slogans on posters located in college dorm room. These lights also appeared in nightclubs and theater productions around the country, creating a surreal atmosphere. Coupled with a strobe light, black lights created a disorienting purple haze. Nowadays, you can still find these black lights in nightclubs. There are more fluorescent materials on the market - paints, dyes, and clothes, markers - that seem to come to life with the existence of the black light.
