Wikipedia Reference Information
Water cure (also known as water torture) is a form of torture which is intended to make the subject feel the sensation of drowning. In the most common variation, the torturer pours water down the throat of the subject to inflict the terror of drowning, without causing the subject to drown. The victim also experiences the pain of stomach distention, and water intoxication. In another variation, the subject is tied or held down in a chair, his face is covered with a cloth or plastic sheet, and water is poured slowly or quickly over his face to encourage him to talk (see "waterboarding" for more detail).
Often the victim has his nose closed with pincers and a funnel forced into his mouth. The victim has to drink all the water (or other liquids such as bile or urine) poured into the funnel to avoid drowning. The stomach fills until near bursting, and is sometimes beaten until the victim vomits and the torture starts over.
