At the height of the séance, she was even able to produce a tiny ectoplasmic hand from her navel, which waved about in the darkness. Her career ended when Harvard biologists were able to examine the tiny hand and found it to be nothing more than a carved piece of animal liver."
In 1907, Hereward Carrington exposed the tricks of fraudulent mediums such as those used in slate-writing, table-turning, trumpet mediumship, materializations, sealed-letter reading and spirit photography. between 1908 and 1914 the Italian medium Francesco Carancini was investigated by psychical researchers and they discovered that he used phosphorus matches to produce "spirit lights" and with a freed hand would move objects in the séance room.
Celtic Cross Tarot card reading predicts your future by reading the cards. This is different from prophesies using calculations of date, time and year of birth. Each prediction or card selection may not indicate the same result. The accuracy depends on your intention and concentration at the time of selection. Thus, it is very important to concentrate hard to achieve the most significant outcome.
