1. The method of creating a spectacular display comprising the steps of forming an elongated stream comprising a body of liquid medium having a first index of refraction into a medium which is ambient atmosphere having a second index of refraction lower than the first index of refraction to provide a substantially smooth continuous outer boundary surface enclosing the stream and contacting the ambient atmosphere, introducing light of a certain intensity directly into the body of liquid forming the stream closely adjacent the formation of the stream at its emergence into ambient atmosphere and in the direction of liquid flow in the stream in such a manner that light striking the outer boundary surface at an angle of incidence greater than or equal to the critical angle for the media is initially guided downstream within the liquid at substantially the same intensity by the phenomenon of total internal reflection of light in the stream, and creating a spectacular display by controlling the exit of light from the stream.
