Home was investigated by Crookes in a self-built laboratory at the rear of his house at Mornington Road, North London in 1871. No plans of the laboratory have been found and there is no contemporary description of it. Crookes wrote the board and spring balance experiment was a success with Home and had proven "beyond doubt" the existence of a "psychic force." However, the experiment could be easily dismissed as the result of vibrations caused by the passage of Euston trains in the large railway cutting near his house in London. The experiment was not repeatable and sometimes failed to produce any phenomena. The experiment was rejected and ridiculed by the scientific community for lack of scientific controls. In the experiment Home refused for Crookes to be near him and would draw attention to something on the other side of the room, or make conversation for diversionary signals.
