Here's Richard Feynman on sensory deprivation tanks: http://pastebin.com/42YhjjYg

From his book "Surely You're Joking, Mr. Feynman!"[1].

> [...] convinced that a council of invisible cosmic entities governed reality.

Kind of odd to throw that out as an affirmation of this man's eccentricity, when billions of human beings consider this absolutely normal.


Perhaps somewhat related. The other day I read that DMT produces psychedelic experiences that often involve a common thread that is somewhat similar to a "council of invisible cosmic entities:" multiple technologically advanced entities.

     Strassman (2001) reported that “about half” of the 60 volunteers entered 
     what he described as “freestanding, independent levels of existence” of a 
     highly unusual nature. These places were inhabited by what volunteers 
     described as intelligent “beings”, “entities”, “aliens”, “guides”, and 
     “helpers”... ...Strangely enough, reports of these kinds of beings seem 
     to be unique to DMT, as Strassman was unable to find anything similar in 
     the research literature on other psychedelic drugs.   
     
     There were some consistent themes in experiences of entity contact. 
     Participants frequently reported that the beings seemed to be waiting for 
     them. Volunteers were subjected to an examination by these beings in what 
     appeared to be a technologically advanced setting. Volunteers felt 
     like their mind and body was probed and tested, or even modified in some 
     unexplained way. The beings communicated with the user through gestures
     
     ...Strassman noted the striking parallels between these entity contact 
     experiences and accounts of alien abduction. 
     
     Intriguingly, many volunteers refused to believe that these experiences 
     were hallucinations or dreams, as they seemed too real. Strassman reported 
     being initially quite baffled by and unprepared for the frequency of these 
     entity experiences among his volunteers...
As an atheist and somebody who has never used psychedelics I find this fascinating.


It's all about how many other people share your belief.

If it just you or a small handful of people, you're crazy or eccentric. If it's a few hundred you start getting into the cultist region. Pass a few thousand and you become religious.

Yes, those number were pulled out of thin air, but the sentiment remains.


I've been to 5 different float centers and every single one cites Joe Rogan as the inspiration for starting. Kind of amazing.

Also, I'm working on a VR setup to use in the tank. Still in its infancy, but shows some promise!

You already have a VR setup. Just get in the tank!


Joe Rogan is cool and all, but the stuff he praises is often in line with "whoa, i took this and it opened my eyes to the REAL reality, man". Not much science or thoroughness behind anything. One time I listened to this podcast where he was trying to sound scientific when questioning the moon landing, but it was just as weak as the "where are the astronaut's shadows" people.


I know exactly what you're saying; that stuff would drive me crazy in his podcasts.

I figured out he was just very much biased toward things that are exciting. Things like the moon landing being fake, or bigfoot being real, etc. And while he gave that stuff probably too much benefit of the doubt, he isn't immune to evidence or rationality.

For instance, Bigfoot and the moon landing conspiracy stuff are now dealt with in a politic "I personally can't disprove it, but it seems pretty unlikely, and all the evidence tends to come from people who are thoroughly full of shit".

And since the SyFy show, he seems to take a much more skeptical view on new assertions.

Except when it comes to Graham Hancock, Randall Carlson, et al. They still get a lot of slack. But even then, he tries to steer it toward the tangible archaeological/geological data and away from the woo-woo conclusions.


Actually, while being in tank today I thought that it would be a blast to have a VR headset on while in the tank.

So did you manage to float with the headset ? How does it feel ?


I did this once. I fell asleep. After 2.5 hours (I had only reserved one hour), they came banging on the tank to wake me up.


I'm one of the engineers contracted to build new hardware and software controllers for one of the major suppliers of these tank systems. There are intercoms now, better temp control, better lighting abilities, and much more. Though, we still need a iOS and Android app.


Float tanks rock! Note to newbies; you need about 3 sessions to really get into it and learn to let go faster.

Forget sitting meditation. Flotation therapy is the easiest way to get a brain and body massage. There are also heath benefits from the Epsom Salt used inside the tank to make you float.

I wrote a bit on this topic few years back here: http://www.theroadtosiliconvalley.com/local-california/float... and why it's a perfect tool for engineers to let go and relax after a busy day of coding ;-)


After reading this article, I just went ahead and did a floatation session and here I am back after my first 1 hour float.

It was a great experience and 1 hour is definetely not enough to understand it all, but there is a lot of potential there.

The physical sensation itself is really interesting - you feel like a fish and you want to move like a fish in there (doing S movements with your body), then you hear the sound of your bones cracking and liquids moving through your body. The most disturbing was the sheer noise that I constantly have in my ears - a kind of tinnitis which resembles the sounds of a modem and it felt like the noise amplified as I was thinking about emotional things.

You also realise just how much sensorial input our mind processes at any point and how much of reality is filtered away automatically.

I had just a couple of instances when I really 'floated away' for maybe a couple of seconds, but then my mind would always jump back and take control of the situation.

I suppose if I go to more sessions, I will learn how to extend them and go deeper and deeper into the meditative trance state.

The feeling of not having all this sensory input made me feel small, almost microscopic to the point of wondering - who am I, really ?

And that is a good question to ask yourself.

35 EUR/hour is a bit expensive though - but they have sliding prices if you buy more sessions so I'm probably going to do that.


> then my mind would always jump back and take control of the situation.

In Buddhist lingo, that's the Self, always clinging to sense-impressions, trying to manipulate them and mistaking them as something personal.


Tried this out a few months back. Wrote my experience up here - http://impossiblehq.com/sensory-deprivation-tank/


In my experience, float tanks are "fine" but nothing that great. Typically you can rent them by the hour, and I got the feeling that to truly experience one, you'd need to do it for multiple hours, or perhaps even a day.

Apparently Feynman enjoyed them, and even smoked marijuana before entering them on a couple occasions. Not something I'd do, but, I can imagine that would add to the effect.

One warning if you try the tank: the water is extremely salty...so if you get an itch anywhere on your face, be sure the water doesn't contact your eye... man does it burn.


Poor man's alternative - a meditation eye mask that gives you total darkness, a good set of earplugs for silence, and a comfy mattress or just sit in a regular meditation position. After 30 minutes, the lack of spatial information and total silence removes you from your surroundings, you get a feeling that you don't know any more where you are, there is no world, just your mind. Can be scary or impressive.


> just sit in a regular meditation position.

Why not lie down?


You're more likely to fall asleep when lying down.


I've been a few times. I think a good session is 90 minutes. 60 seems too short for me but 90 is good enough to get the full experience. You really have to know how to relax though.


There's one in San Diego called Flot and the owner recommends at least two hours. I booked it and must've floated for closer to three, which was about right. It had three stages:

1. Mind racing, everyday worries at hand (~45-60 minutes)

2. Thinking through actual concerns and whats important (~30 mins)

3. Complete relaxation

It's an incredible experience if you devote the time to it, but to really feel it you need to get through the first stage which can take over an hour. I left happier and more peaceful than I had been in some time.


I suspect mine would go like this:

1. Mind wandering (~5-10 minutes)

2. Sleep (~whatever time is left)

What keeps you awake all that time?


There's a lot going on in my life and a lot I want to improve personally. Some of these things keep me wired.


Maybe it's just me but I find smoking beforehand to be a shortcut to step 2.


Depends on the strain, not sure if I'd go into one of these after smoking a sativa-dominant strain.


That's exactly what I go for :)


I'd like to try it for an entire night. I've been meaning to ask my local float spa if that's something they'd be open to trying.

Along with avoiding water in the eyes, also be cautious of any open cuts or wounds (from shaving or blisters) - they sting just as much!


> The film’s success spoke to floating’s ongoing mystical allure. After sports teams such as the Philadelphia Eagles and the Philadelphia Phillies installed float tanks in their training facilities in 1980, they won the Super Bowl and World Series respectively. By the middle of that decade, celebrities from John Lennon to Robin Williams had acquired tanks.

Err... John Lennon died in 1980. The Eagles lost the 1981 Super Bowl. What other inaccuracies might be in the article?


Apparently John Lennon used a floatation tank in 1979: http://www.apnewsarchive.com/1988/Bio-Lennon-Kicked-Heroin-H...

The Eagles did lose the 81 Super Bowl, but maybe it's a typo for "made it to the Super Bowl", which is considered an achievement in itself in sports? (particularly if the team had a poor track record the years prior)


Yeah, and by the mid-1990's no one was using them, which is the adoption curve that's characteristic of a fad, not an effective method of doing anything useful. Now 20 years later the fad is back, right on schedule. Expect it to last five to ten years (closer to five) then drop off as people lose interest because once the novelty wears off there is nothing to go back for.


Ha, the Altered States movie instantly came to mind just by association with the headline. Read down a few paragraphs and, hey, there it is!

I saw the movie as a kid on late night TV. One fine day just a couple of years ago, I suddenly remembered it, googled for a while (not remembering its name) and watched it again.

The movie contains a Jeckyll-and-Hyde trope which is so laughably impossible that the screenwriters don't even bother trying to weave in a shred of a plausible explanation for it that a seasoned sci-fi aficionado could swallow. If you can get past that, the film as such is decent and entertaining. Certainly enough to impress a twelve-year-old kid into looking for it thirty years later to watch again.


Are these useful to someone with tinnitus, or does the ringing render them intolerable?


No worse than normal, at least for me. I found the experience dull. Always having some internal auditory stimulation may have been part of the cause of that.

Also, I meditate very easily and prefer a whitenoise environment for meditation. And I'm very happy in my own head and used to being alone. So the whole thing was not much a novelty in any respect, and the lack of whitenoise made it suboptimal for meditation.

I wonder how people's response to these things varies as they move along the extroverion-introversion scale. It seems plausible that extroverts would find them a much more novel and disturbing experience than introverts.


The fact that a float tank would never be true sensory deprivation makes me sad.

Having tinnitus drives me crazy. Not in literal sense, it's not like I focus on it all the time. But at night when I hear the crickets and other nightlife, I mourn the lack of silence in my head.


Good to know before I reserve time in one. Thanks.


For those who want to try it out in San Francisco, Reboot Float Spa[1] is a great facility.

It would be great to float in there and have VR (Oculus Rift or similar), that could end up being a very immersive experience (pun intended :P)
