A series of mediumistic séances known as the Scole Experiment took place between 1993–98 in the presence of the researchers David Fontana, Arthur Ellison and Montague Keen. This has produced photographs, audio recordings and physical objects which appeared in the dark séance room (known as apports).[185] A criticism of the experiment was that it was flawed because it did not rule out the possibility of fraud. The skeptical investigator Brian Dunning wrote the Scole experiments fail in many ways. The séances were held in the basement of two of the mediums, only total darkness was allowed with no night vision apparatus as it might "frighten the spirits away". The box containing the film was not examined and could easily have been accessible to fraud. And finally, even though many years have passed, there has been no follow-up, no further research by any credible agency or published accounts.[186] The Scole experiment was also criticized by the psychical researchers Tony Cornell, Alan Gauld and Donald West. Gauld wrote there was "quite a lot of indirect evidence" for fraud in the experiment, Cornell wrote normal explanations could be given for the séance phenomena and West wrote the Scole report was "sadly unconvincing" due to lack of scientific controls.

Google "Scole Project", and you will find many other references which point out huge flaws in the testing procedure.
Clearly, the Scole Project is junk science, and can safely be ignored.
