Black light theatre (in Czech černé divadlo) or simply black theatre , is a theatrical performance style characterized by the use of black box theatre augmented by black light illusion. It has become a speciality of Prague , where many theatres use it.
Black Theatre[Also called Black Light Theatre] A theatrical technique that allows the puppeteer to make certain objects and characters or puppets appear before the public whilst at the same time hiding others and themselves.
How are they made and what are they made of ? Firstly, a pitch black theatre is required with a black back drop generally made of black velvet. This is to help make the puppets and props glow. The puppeteers are needed to wear a full body costume also made of black velvet.
A black light is a type of lamp that emits primarily ultraviolet light and very little visible light . Because the light is outside the range of human vision, it is invisible, so a room illuminated with a black light appears dark.
Black lights are required to observe fluorescence, since other types of ultraviolet lamps emit visible light which drowns out the dim fluorescent glow. Black light is commonly used to authenticate oil paintings, antiques and banknotes.
A type of puppet that demands different techniques of animation based on the body of the puppeteer. These puppets could be defined by default, in the sense that they are not costume puppets . Yet they all show an important part of the puppeteer’s body .
Ultraviolet ( uv ) Performance. Performances using ultraviolet ( uv ) light are mesmerizing to watch. Under ultraviolet light (black light), a performer moving brightly coloured equipment can create optical traces in the paths of objects.
A puppet is an object, often resembling a human, animal or mythical figure, that is animated or manipulated by a person called a puppeteer. The puppeteer uses movements of their hands, arms, or control devices such as rods or strings to move the body, head, limbs, and in some cases the mouth and eyes of the puppet .

2 Answers. There are several kinds of ” UV Light .” Only kind I know of that “looks purple ” is a so-called black light . Black lights emit UV that is very close to the top-end of the visible spectrum. The visible leakage from a black light stimulates both “red” and “blue” receptors in your eye, and you perceive purple .
You can see chemicals, dust, traces of blood, fungusbut not germs . I do not think it will show many germs because not many germs will glow under a black light . But it can be used to demonstrate how germs can spread if you put something on your hands that does glow like laundry detergent or a dye.
