The Purpose and Setup of Sensory Deprivation Tanks

sensory-deprevation-tankSensory deprivation involves a large tank which is filled up with water heated to 37 degrees Celsius, the same temperature as the body, and 1000 lbs., or some variation of this in smaller tanks, of Epsom salts are added, so that half of the body is underwater and half of it is above because of the density of the salt within the water. Human beings have low fat content on average and need this salt otherwise a participant would sink. An observer cannot distinguish between water and air because when within the tank as it feels the same, and after a short period of time, because there are no visual queues being that the tank is completely dark, in the absence of sensory input, an observer typically begins to think differently as the brain has more resources dedicated to thought as less surface area is compartmentalized for sensory stimuli. This process is extremely similar to meditation, however meditation takes both time and practice to achieve upon a consistent, reliable, and meaningful level, as opposed to a sensory deprivation tank in which reaching such a state is essentially automatic provided enough time passes within the tank for the observer. This experience ends instantaneously once the tanks door is opened however, unlike meditation or the use of pharmacological agents to achieve a psychedelic or intrinsic experience

The Sinking of the USS Thresher

The USS Thresher was the first ever U.S. submarine to sink to the seafloor. It’s hypothesized by some military experts that the infamous John Walker who was acting as a mole within the U.S. Navy, tipped off the Russians as to the location of the USS Thresher and that the submarine was attacked in revenge for a Soviet submarine entitled “K-129” which was lost 10 weeks prior to the USS Thresher event. The Russians believed that a U.S. Navy Destroyer ship ran over and through the Russian submarine K-129 despite the U.S. Navy claiming no involvement whatsoever. The forensic evidence points towards implosion due to a leak of some kind, most likely near the seals of the propeller or the trash shoot, making it impossible for the USS Thresher to rise to the surface or be saved by a nearby vessel
