Psychic telephone

The psychic telephone was an instrument invented by F. R. Melton of Nottingham, UK, consisting of a box containing a rubber bag connected with a pair of earphones from a wireless set. The idea was that, if a medium inflates the bag with her breath and then seals it, the bag takes the place of the medium and directs voices to be heard through the earphones in the medium's absence. The psychic telephone is not a form of telephone conversation but rather a wireless one using radio device.

The psychical researcher Harry Price subjected the instrument to a thorough test in the National Laboratory of Psychical Research. He concluded that it did not work.
