Originally appearing here. You can own Timothy Leary’s sensory deprivation tank! The Samadhi Tank Company delivered the tank to Tim the month before he died. I don’t know how often Tim used it, but I remember seeing it in the corner of his bedroom. Tim’s tank is on eBay for a Buy It Now price of $20,000 with the proceeds going to the nonprofit Multidisciplinary Association for Psychedelic Studies.

The “floatation tank,” sometimes called the isolation or sensory deprivation tank, was developed in the mid-1950’s by psychoanalyst and consciousness researcher John C. Lilly, M.D. Lilly used the isolation tank to test the relationship between the mind and external reality. After extensive experimentation with the tank, he came to explore it for many potential applications, ranging from increasing creative problem-solving ability to facilitating meditation and prayer. This tank was originally owned by the controversial psychedelic researcher Timothy Leary. In February of 1996, Dr. Lilly and the Samadhi Tank Company delivered the tank to Dr. Leary to help ease his end-of-life suffering. The current owner is Dean Chamberlain, photographer and renowned visionary artist who has generously agreed to share proceeds from the sale with MAPS to benefit of psychedelic and medical marijuana research and education.
