T.G. started with the use of Ouija board and experiments with mental telepathy with his United Church minister, Reverend Daniel Normal McLachlan. The family’s first medium was their Scottish nanny, Elizabeth Poole. She started out by using the Ouija board, but moved on in 1920 when the family was introduced to table tipping, where a table would stop tipping when the “correct” letter was pronounced aloud, somewhat akin to the Ouija board. This led to investigations into telekinesis, or the movement of physical objects through mental exertions. By now T.G. had established a separate room on the 2nd floor of the house which was to be kept locked at all times when it was not in use. T.G. wanted to investigate paranormal phenomena such as rappings, psychokinesis, ectoplasms, and materializations under scientific conditions that would minimize any possibility of error. A red bulb in the centre of the room provided light. A bank of about a dozen cameras were focussed on the side of the room where activity was to take place, their shutters open, waiting for Hamilton to set off a flash in order for them to all take photos at the same time. A three sided wooden cabinet that T.G. constructed open on one side was used in the telekinesis experiments, where Mrs. Poole would charge a small table by laying her hands on it, causing it to move from the cabinet.
