Completely briefly to begin with, nothing the bad what separate the quite great!
A Floating tank, or Samadhi-Tank or isolation-tank how he is also called, can introduce itself, one as a bathtub which is completely isolated with a bonnet against light and noises. In the tub no normal water is used, but very strongly concentrated sole solution. With thus it is reached that the human body as a result of the lower specific gravity does not decline in comparison to salted water. One knows a similar effect from the dead sea.
The water and the space air in the Floatation tank is heated on 34.5°C and has with it that temperature resembles like the skin surface. If one lies down now in the tank and concludes the lid, all stimuli are took away and one can concentrate only upon himself. Light, noises, temperature and gravity become so no more discernible, one freely seems to float in an infinite space.
By the denial all visual, acoustic and tactile stimuli one also reaches as more unskilled very fast in very much a deep ruminant state which is felt by most users of the Floating tank as very pleasant and relaxative.
The Floating tank was invented in 1954 by John C. Lilly and at that time served a research program in the psychology. By the strengthening of the wellness movement the Floating tank has found a quite new regulation.
