VIDEO: This one time... I went in a sensory deprivation tank.
NASA might not be calling me anytime soon, but my little pod felt like my very own space ship. Inside I was immersed in complete darkness, with no auditory stimulation, and after what seemed like 10 minutes I had no concept of what was above or below water. UMMMM TRIPPY.
Because the water is kept at the same temperature as the air in the tank eventually you habituate to the feeling of the water against your skin and it truly feels like you are hovering in your little space pod. The water has roughly 1000 pounds of epsom salt dissolved in it, meaning this water is ridiculously dense and no matter how hard you try, you can't submerge yourself (trust me, I tried), hence the name "float".
Why float? Epsom salt = major perks.
Relaxation. Detoxification. Relief of muscular pain. And you might have visual hallucinations as a boomerang effect from the lack of sensory stimulation.
WORDS OF ADVICE!!!
Pee before hand, full bladders are the worst
Stay open minded, see where your imagination takes you
DON'T TOUCH YOUR EYES!
