The Deep Joy
July 20, 2017 2:42 PM   Subscribe

Y-40 "The Deep Joy" pool first opened on 5 June 2014 and was designed by architect Emanuele Boaretto. It is 40 metres (131 ft) deep, making it the deepest pool in the world. It contains 4,300 cubic metres (1,136,000 US gal) of thermal water kept at a temperature of 32–34 °C (90–93 °F). Watch Guillaume Néry go deep. posted by chavenet (57 comments total) 20 users marked this as a favorite
 
Deep water makes me nervous. I feel anxious just knowing that this thing exists.

It was like, this is okay but wow it's really deep and it's making me nervous, and then NOOOOOO WHATEVER YOU DO DON'T GO DOWN THERE!!!!!

This is pretty awesome.

I was getting really uncomfortable watching this guy freediving that deep until I read the Wikipedia link. Dude went to -117 meters in Kalamata in 2011, so as deep as this seems, he's been almost three times as deep (and back, presumably). Blows my mind.

There was a video like this from way back but it was into some sort of natural ocean rift? With good music? It's not in any of the previousliers. Anyone?

Oh wait, might be the the third one.

The uh vestibular, kind of deep parts look fun--I could see puttering around in there to see how deep I could go. That final, round well, though--lol no.

He's still down there. Seems comfortable enough. Likes to go around in little circles and play with the lamp. They sprinkle in food pellets twice a day.

I notice in the comments, it says that bats are not people, which, if it's true, seems like the real story here.

What happens when they pull the plug out at the bottom? How vast would the drainage need to be to accommodate that volume of water, at that velocity? It would need to be as wide as the well itself. So does that-...is this thing infinitely deep?

Dammit, I said I wanted you to build me a pool hall!

The hotel is only 20m above sea level, and certainly even less above the ground water level. If you want to drain this pool, you need a pump.

This looks like a flooded stage from Portal.

Oh, yeah- this level is tricky.

You have to open one portal near the bottom, and another in the next room over, so that all the water drains out into the lava channel.

I'm sort of upset they didn't show him coming back up.

The diagram in the Independent is fuzzy, but I notice there are three naked guys standing around the pool. Moreover, they're identical. I think they must be clones, and this is a Neolution experiment.

I wouldn't mind going down there in scuba gear, if they didn't find it a gross impiety.
posted by Mr.Encyclopedia at 8:56 PM on July 20


Kinda crazy to think that at that depth even hanging out at the bottom with a scuba tank for a short time will net you significant amounts of decompression time on the way back up. 130 feet is deep.

I had to breathe SO MANY TIMES while watching that.

Interesting. I know that the water is less dense at 34 °C, and he seems to have very low body fat, but he still descends a lot faster than I would expect without weights.

Somewhere around 100ft a free diver will no longer be buoyant and will naturally sink.

They let people scuba dive. I imagine one of the reasons 40m was chosen is that's the generally-recommended maximum depth for recreational divers breathing regular compressed air.

I am so throwing a Baby Ruth bar in that.

Wuh? I don't understand why he's not having to equalise on his way down. I'm pinching my nose at least every metre when I scuba dive. What's his secret?

According to my dive computer he'd have about 6-7 minutes on the bottom without having to decompress. I wonder how long he can hold his breath.

The former pool manager in me wants to know....how do you vacuum that thing? You have to...just think of all the hair, lost rings, hairbands and general stuff that would end up at the bottom...eventually, it would get a layer of sludge.

dowcrag : He is equalizing (unless he's one of those sinus-flooding types). There are alternatives to Valsalva.

Just reading rhamphorhynchus' link made me nervous.

The only reason I didn't run screaming from the room is that there was no shot from the lowest point looking back up. If the film had shown that - a small circle of light, far away, that is also your only place to get more air - I don't think I'd have slept for days for fear of the nightmares to come.

Rhamphorhynchus, that's my lack of diving experience showing. Don't like the sound of some of those alternatives, though!

Fear of heights kicking in while underwater? Nope. Nope. Nooooooooooooope.

There is not enough nope in the world for that. And I love being in water.

That was fascinating to watch. I am utterly amazed that any human can hold his/her breath for more than about 90 seconds.

Also, I think that there should be an end title on the video similar to certain old TV shows:

THE
END

This could only be improved by putting a scary clown mannequin, half in shadow, at the bottom.

I'm impressed at how they managed to get all that continuous film and not include any of the scuba-diving photographers.

I don't think decompression is an issue if you aren't breathing compressed air. You don't get a lot of gas forced into your blood if you don't bringing a lot of extra gas with you.

Though also he's not holding his breath for 6 minutes, so another reason it's not a factor.

This is true. I think I ended up gasping for air 4 times while it was showing. I tried watching again and breathing consciously and just about managed to not get short of air.

Because we don't have gills.

Honestly, I think the main thing I would do is sit on the edge of the pool and throw quarters in. After all, you're going to need something to do once you reach the bottom.

That temp is too hot. The depth would be fun bit 90 degree water is repulsive.
