Anyone heard of these or tried one out? Are they for people who are scared to try shrooms, acid, shrooms, or dmt? I've been thinking about "expanding my mind" after that red pill thread Speakeasy made.

I went to one a few months ago. I think it was about 50 bucks for an hour. It was definitely relaxing and a cool feeling. I may have had some milld auditory hallucinations, not sure. They say you don't really get all the benefits until several sessions. I would probably go more if it were closer.

Apparently Joe Rogan is a big believer in it and has several YouTube videos about it.

I've done it. I was in there for about 4 hours. I didn't hallucinate, but I did lose track of space and time and was half dreaming/awake for most of the time. Very relaxing, and good for doing some deep contemplative thinking.

Somewhat weird coincidence. There was no set limit on the time of my float session. I could just end it whenever I felt like. My buddy was in a float tank in the neighbouring room. Somehow, despite the chamber being insulated from all external sounds and stimuli, we both felt it was time to end the session at the exact same time. I literally heard him exiting his chamber as I exited mine.

I'd do it again. Some of them have tv's and speakers set up inside, so you can put on some tunes or a video and tune out everything else to focus on this one stimuli. The operator of the float lab told me that fighters would occasionally float in the tanks while watching tape of upcoming opponents. Also, graduate students would come to float while listening to lecture tapes and have intense learning sessions.

Joe Rogan has many videos and comments about Hallucination generating drugs like DMT. Very interesting stuff I suggest to check out.

It sounds like you shouldn't go in one if you're stressed about things in your life.

Player, pimp, physicist, Nobel Laureate Richard Feynman documented his experiences with isolation tanks:

• Altered States
  I used to give a lecture every Wednesday over at the Hughes Aircraft Company, and one day I got there a little ahead of time, and was flirting
  around with the receptionist, as usual, when about half a dozen people came in--a man, a woman, and a few others. I had never seen them before. The
  man said, "Is this where Professor Feynman is giving some lectures?"
  "This is the place," the receptionist replied.
  The man asks if his group can come to the lectures.
  "I don't think you'd like 'em much," I say. "They're kind of technical."
  Pretty soon the woman, who was rather clever, figured it out: "I bet you're Professor Feynman!"
  It turned out the man was John Lilly, who had earlier done some work with dolphins. He and his wife were doing some research into sense
  deprivation, and had built some tanks.
  "Isn't it true that you're supposed to get hallucinations under those circumstances?" I asked, excitedly.
  "That is true indeed."
  I had always had this fascination with the images from dreams and other images that come to the mind that haven't got a direct sensory source,
  and how it works in the head, and I wanted to see hallucinations. I had once thought to take drugs, but I got kind of scared of that: I love to think, and
  I don't want to screw up the machine. But it seemed to me that just lying around in a sense-deprivation tank had no physiological danger, SO I was
  very anxious to try it.
  I quickly accepted the Lillys' invitation to use the tanks, a very kind invitation on their part, and they came to listen to the lecture with their group.
  So the following week I went to try the tanks. Mr. Lilly introduced me to the tanks as he must have done with other people. There were lots of
  bulbs, like neon lights, with different gases in them. He showed me the Periodic Table and made up a lot of mystic hokey-poke about different kinds
  of lights that have different kinds of influences. He told me how you get ready to go into the tank by looking at yourself in the mirror with your nose
  up against it--all kinds of wicky-wack things, all kinds of gorp. I didn't pay any attention to the gorp, but I did everything because I wanted to get into
  the tanks, and I also thought that perhaps such preparations might make it easier to have hallucinations. So I went through everything according to the
  way he said. The only thing that proved difficult was choosing what color light I wanted, especially as the tank was supposed to be dark inside.
  A sense-deprivation tank is like a big bathtub, but with a cover that comes down. It's completely dark inside, and because the cover is thick,
  there's no sound. There's a little pump that pumps air in, but it turns out you don't need to worry about air because the volume of air is rather large,
  and you're only in there for two or three hours, and you don't really consume a lot of air when you breathe normally. Mr. Lilly said that the pumps
  were there to put people at ease, so I figured it's just psychological, and asked him to turn the pump off, because it made a little bit of noise.
  The water in the tank has Epsom salts in it to make it denser than normal water, so you float in it rather easily. The temperature is kept at body
  temperature, or 94, or something-- he had it all figured out. There wasn't supposed to be any light, any sound, any temperature sensation, no nothing!
  Once in a while you might drift over to the side and bump slightly, or because of condensation on the ceiling of the tank a drop of water might fall,
  but these slight disturbances were very rare.
  I must have gone about a dozen times, each time spending about two and a half hours in the tank. The first time I didn't get any hallucinations,
  but after I had been in the tank, the Lillys introduced me to a man billed as a medical doctor, who told me about a drug called ketamine, which was
  used as an anesthetic. I've always been interested in questions related to what happens when you go to sleep, or what happens when you get conked
  out, so they showed me the papers that came with the medicine and gave me one tenth of the normal dose.
  I got this strange kind of feeling which I've never been able to figure out whenever I tried to characterize what the effect was. For instance, the
  drug had quite an effect on my vision; I felt I couldn't see clearly. But when I'd look hard at something, it would be OK. It was sort of as if you didn't
  care to look at things; you're sloppily doing this and that, feeling kind of woozy, but as soon as you look, and concentrate, everything is, for a
  moment at least, all right. I took a book they had on organic chemistry and looked at a table full of complicated substances, and to my surprise was
  able to read them.
  I did all kinds of other things, like moving my hands toward each other from a distance to see if my fingers would touch each other, and although
  I had a feeling of complete disorientation, a feeling of an inability to do practically anything, I never found a specific thing that I couldn't do.
  As I said before, the first time in the tank I didn't get any hallucinations, and the second time I didn't get any hallucinations. But the Lillys were
  very interesting people; I enjoyed them very, very much. They often gave me lunch, and so on, and after a while we discussed things on a different
  level than the early stuff with the lights. I realized that other people had found the sense-deprivation tank somewhat frightening, but to me it was a
  pretty interesting invention. I wasn't afraid because I knew what it was: it was just a tank of Epsom salts.
  The third time there was a man visiting--I met many interesting people there--who went by the name Baba Ram Das. He was a fella from
  Harvard who had gone to India and had written a popular book called Be Here Now. He related how his guru in India told him how to have an "out -
  of-body experience" (words I had often seen written on the bulletin board): Concentrate on your breat h, on how it goes in and out of your nose as you
  breathe.
  I figured I'd try anything to get a hallucination, and went into the tank. At some stage of the game I suddenly realized that --it's hard to explain--
  I'm an inch to one side. In other words, where my breath is going, in and out, in and out, is not centered: My ego is off to one side a little bit, by about
  an inch.
  I thought: "Now where is the ego located? I know everybody thinks the seat of thinking is in the brain, but how do they know that?" I knew
  already from reading things that it wasn't so obvious to people before a lot of psychological studies were made. The Greeks thought the seat of
  thinking was in the liver, for instance. I wondered, "Is it possible that where the ego is located is learned by children looking at people putting their hand to their head when they say, 'Let me think'? Therefore the idea that the ego is located up there, behind the eyes, might be conventional!" I
  figured that if I could move my ego an inch to one side, I could move it further. This was the beginning of my hallucinations.
  I tried and after a while I got my ego to go down through my neck into the middle of my chest. When a drop of water came down and hit me on
  the shoulder, I felt it "up there," above where "I" was. Every time a drop came I was startled a little bit, and my ego would jump back up through the
  neck to the usual place. Then I would have to work my way down again. At first it took a lot of work to go down each time, but gradually it got easier.
  I was able to get myself all the way down to the loins, to one side, but that was about as far as I could go for quite a while.
  It was another time I was in the tank when I decided that if I could move myself to my loins, I should he able to get completely outside of my
  body. So I was able to "sit to one side." It's hard to explain--I'd move my hands and shake the water, and although I couldn't see them, I knew where
  they were. But unlike in real life, where the hands are to each side, part way down, they were both to one side! The feeling in my fingers and
  everything else was exactly the same as normal, only my ego was sitting outside, "observing" all this.
  From then on I had hallucinations almost every time, and was able to move further and further outside of my body. It developed that when I
  would move my hands I would see them as sort of mechanical things that were going up and down--they weren't flesh; they were mechanical. But I
  was still able to feel everything. The feelings would be exactly consistent with the motion, but I also had this feeling of "he is that." "I" even got out
  of the room, ultimately, and wandered about, going some distance to locations where things happened that I had seen earlier another day.
  I had many types of out-of-the-body experiences. One time, for example, I could "see" the back of my head, with my hands resting against it.
  When I moved my fingers, I saw them move, but between the fingers and the thumb I saw the blue sky. Of course that wasn't right; it was a
  hallucination. But the point is that as I moved my fingers, their movement was exactly consistent with the motion that I was imagining that I was
  seeing. The entire imagery would appear, and be consistent with what you feel and are doing, much like when you slowly wake up in the morning
  and are touching something (and you don't know what it is), and suddenly it becomes clear what it is. So the entire imagery would suddenly appear,
  except it's unusual, in the sense that you usually would imagine the ego to be located in front of the back of the head, but instead you have it behind
  the back of the head.
  One of the things that perpetually bothered me, psychologically, while I was having a hallucination, was that I might have fallen asleep and
  would therefore be only dreaming. I had already had some experience with dreams, and I wanted a new experience. It was kind of dopey, because
  when you're having hallucinations, and things like that, you're not very sharp, so you do these dumb things that you set your mind to do, such as
  checking that you're not dreaming. So I perpetually was checking that I wasn't dreaming by--since my hands were often behind my head--rubbing my
  thumbs together, back and forth, feeling them. Of course I could have been dreaming that, but I wasn't: I knew it was real.
  After the very beginning, when the excitement of having a hallucination made them "jump out," or stop happening, I was able to relax and have
  long hallucinations.
  A week or two after, I was thinking a great deal about how the brain works compared to how a computing machine works--especially how
  information is stored. One of the interesting problems in this area is how memories are stored in the brain: You can get at them from so many
  directions compared to a machine--you don't have to come directly with the correct address to the memory. If I want to get at the word "rent," for
  example, I can be filling in a crossword puzzle, looking for a four-letter word that begins with r and ends in t; I can be thinking of types of income, or
  activities such as borrowing and lending; this in turn can lead to all sorts of other related memories or information. I was thinking about how to make
  an "imitating machine," which would learn language as a child does: you would talk to the machine. But I couldn't figure out how to store the stuff in
  an organized way so the machine could get it out for its own purposes.
  When I went into the tank that week, and had my hallucination, I tried to think of very early memories. I kept saying to myself, "It's gotta be
  earlier; it's gotta be earlier"--I was never satisfied that the memories were early enough. When I got a very early memory--let's say from my home
  town of Far Rockaway--then immediately would come a whole sequence of memories, all from the town of Far Rockaway. If I then would think of
  something from another city--Cedarhurst, or something--then a whole lot of stuff that was associated with Cedarhurst would come. And so I realized
  that things are stored according to the location where you had the experience.
  I felt pretty good about this discovery, and came out of the tank, had a shower, got dressed, and so forth, and started driving to Hughes Aircraft
  to give my weekly lecture. It was therefore about forty-five minutes after I came out of the tank that I suddenly realized for the first time that I hadn't
  the slightest idea of how memories are stored in the brain; all I had was a hallucination as to how memories are stored in the brain! What I had
  "discovered" had nothing to do with the way memories are stored in the brain; it had to do with the way I was playing games with myself.
  In our numerous discussions about hallucinations on my earlier visits, I had been trying to explain to Lilly and others that the imagination that
  things are real does not represent true reality. If you see golden globes, or something, several times, and they talk to you during your hallucination
  and tell you they are another intelligence, it doesn't mean they're another intelligence; it just means that you have had this particular hallucination. So
  here I had this tremendous feeling of discovering how memories are stored, and it's surprising that it took forty-five minutes before I realized the
  error that I had been trying to explain to everyone else.
  One of the questions I thought about was whether hallucinations, like dreams, are influenced by what you already have in your mind--from other
  experiences during the day or before, or from things you are expecting to see. The reason, I believe, that I had an out-of-body experience was that we
  were discussing out-of-body experiences just before I went into the tank. And the reason I had a hallucination about how memories are stored in the
  brain was, I think, that I had been thinking about that problem all week.
  I had considerable discussion with the various people there about the reality of experiences. They argued that something is considered real, in
  experimental science, if the experience can be reproduced. Thus when many people see golden globes that talk to them, time after time, the globes
  must be real. My claim was that in such situations there was a bit of discussion previous to going into the tank about the golden globes, so when the
  person hallucinating, with his mind already thinking about golden globes when he went into the tank, sees some approximation of the globes--maybe
  they're blue, or something--he thinks he's reproducing the experience. I felt that I could understand the difference between the type of agreement
  among people whose minds are set to agree, and the kind of agreement that you get in experimental work. It's rather amusing that it's so easy to tell
  the difference-but so hard to define it!
  I believe there's nothing in hallucinations that has anything to do with anything external to the internal psychological state of the person who's
  got the hallucination. But there are nevertheless a lot of experiences by a lot of people who believe there's reality in hallucinations. The same general idea may account for a certain amount of success that interpreters of dreams have. For example, some psychoanalysts interpret dreams by talking
  about the meanings of various symbols. And then, it's not completely impossible that these symbols do appear in dreams that follow. So I think that,
  perhaps, the interpretation of hallucinations and dreams is a self-propagating process: you'll have a general, more or less, success at it, especially if
  you discuss it carefully ahead of time.
  Ordinarily it would take me about fifteen minutes to get a hallucination going, but on a few occasions, when I smoked some marijuana
  beforehand, it came very quickly. But fifteen minutes was fast enough for me.
  One thing that often happened was that as the hallucination was coming on, what you might describe as "garbage" would come: there were
  simply chaotic images--complete, random junk. I tried to remember some of the items of the junk in order to be able to characterize it again, but it
  was particularly difficult to remember. I think I was getting close to the kind of thing that happens when you begin to fall asleep: There are apparent
  logical connections, but when you try to remember what made you think of what you're thinking about, you can't remember. As a matter of fact, you
  soon forget what it is that you're trying to remember. I can only remember things like a white sign with a pimple on it, in Chicago, and then it
  disappears. That kind of stuff all the time.
  Mr. Lilly had a number of different tanks, and we tried a number of different experiments. It didn't seem to make much difference as far as
  hallucinations were concerned, and I became convinced that the tank was unnecessary. Now that I saw what to do, I realized that all you have to do is
  sit quietly --why was it necessary that you had to have everything absolutely super duper?
  So when I'd come home I'd turn out the lights and sit in the living room in a comfortable chair, and try and try--it never worked. I've never been
  able to have a hallucination outside of the tanks. Of course I would like to have done it at home, and I don't doubt that you could meditate and do it if
  you practice, but I didn't practice.

Yup ive been in one. Its really cool and relaxing but also expensive. No visions for me in 3 sessions.
Wish i could afford a tank for my home, i would be in it every day.

I heard tiger Woods has one and visualizes his perfect golf swing in the tank.

[SVK]

This is extremely interesting. Will try it out for sure. Could help with many aspects of life - health, career, stress, creativity, game.
Anybody has any info on where to buy one for home and how much they are?
Seems like it shouldn't be as expensive as it seems to be (it is, after all, basically just floating in salty, body temperature water) Maybe a good business opportunity right there...

[w00t]

the tanks are a couple of grands but you also have to consider electricity and also you have to use a certain kind of salt which is very expensive too!

It seems you can build your own for about $2,500, not bad. If it really works as I imagine this would be much better home improvement than a Jacuzzi or a pool.
