2. Chinese Water Torture
Although Chinese water torture was not invented by the Chinese, it is a powerful form of torture that has a specific method in order for it to be effective.
Supposedly named by Hippolytus De Marsiliis in Italy, either between the 15th or 16th century, he observed that when drops of water fell individually on a stone, a dent gradually appeared; and so he thought the same would occur in human beings.
The victim would be stripped naked in public and tortured while they were ridiculed by the public. New studies have found that periodic water drops are not as effective as random drops of water, as the unpredictability can produce a psychotic break.
