The Stone Tape Projector, it is claimed, can be used to project an image from the energy held within a material object, such as a brick, or a piece of clothing. The projector is nothing more than plasma bulbs that are shone onto smoke from a smoke machine, or a piece of fabric.
Those observing the Projector in action are told to take lots of photographs as this is happening. When they check back they often see faces and other recognisable shapes in the light. These are suggested to be ghosts, but in reality, are nothing more than visual illusions.
The projector takes its name from The Stone Tape theory – a popular idea that suggests inanimate materials and objects might absorb some form of spiritual energy from living beings, and that this “recording” or stored energy, can be released resulting in a display of the recorded activity aka. a ghost apparition.
Due to the speculative nature of The Stone Tape theory there is no evidence that The Stone Tape Projector can do what it is claimed it can do, and the photographs that contain supposed faces and similar are simple illusions caused by the light and/or smoke.
