The best way to eliminate all sensory input is to step inside a sensory deprivation tank. An isolation tank is a lightless, soundproof tank inside which subjects float in salt water at skin temperature. Such tanks are now also used for meditation and relaxation and in alternative medicine. The isolation tank was originally called the sensory deprivation tank. Other names for the isolation tank include flotation tank, float tank, John C. Lilly tank, REST tank, and sensory attenuation tank.
Enjoy the first isolation tank that ships inexpensively, assembles in any room and offers personal sensory deprivation.
You could have your own sensory deprivation tank!
