At 33 meters, Nemo 33 in Brussels, Belgium is the world's deepest indoor pool.

That is a VERY cool idea for scuba training.

I am totally going to go see that this summer. Great post!

...That is just plain too cool. Do they allow people to just dive in equipped with nothing but a swimsuit (and a lifeguard, of course) or is it scuba-exclusive?

That's cool on so many underwater levels.

Cool pool.

Someday, future MeFites will be posting stories about the strange holes found in Belgium. No one will remember how they got there or what their original purpose was. This pool is a mystery in the making.

Now: set it up for lasertag.

Fascinating. But for people who get a bit panicky around beaches, lakes, and other such water places, this is a nightmare waiting to happen.

But it really is fascinating. Wonder why it hasn't been done before? If I was a swimmer/diver/etc, this would be like, the ultimate man-made indoor pool, right?

I know I've played that level -- what first-person-shooter is it from?

This is right out of that stage in Half Life 1 where you need to get through a half-submerged barrier while an exposed electric cable blocks an above-water hole so you can't jump through it, and the only option is to swim for a door just under the waterline while two of those scary shark-eel things are swimming around.

I guess that's ok for instruction, but as far as I'm concerned, the point of scuba diving is the fish. I'd rather go here.

HOLY CARP! I've had nightmares dreams about that pool!

(I love swimming, but the dreams about infinitely deep pools always give me the willies.)

How about diving in a freakin' missile silo?

Dude, how do you clean that thing?

This is in Belgium, right? So it's full of Chimay, right?

Mmmmmmm....!

wanderingmind : looks like the picture on the far right of the second row is a diver without scuba ... possibly a freediver?

There is no decompression chamber listed, so I am wondering how long it will take for someone to make a booboo - other than that, I am making a detour to get to this in the coming months.

My other question is how this was built. How thick does the concrete need to be at 90 feet to support this?

Thanks for sharing this....

But do you have to swim to the bottom to get to the restaurant? Because that would be cool. You dive down to the bottom of the pool, swim through a passage, and emerge in a room 33 meters down, pressurized to keep the water from welling up in it. You remove your gear and what have you, towel off, and enter the dining room proper, where you're seated. Everything you order is put on a tab against a pre-authorized credit card, and you bill is paid once you're back topside.

Then again, I was never good enough at pressures to know what that would do to one's dining experience, or the food preparation.

Or -- if you're both claustrophobic and afraid of deep water, like I am -- an inspiration for a screaming panic attack. I got tense just looking at the photos. Add that I would have to take a plane to get there, and woo! It's the perfect trifecta!

Look at a box of cake mix -- they have high-altitude instructions for baking. The lower the air pressure, the lower the boiling point of liquids.

Anecdote from aboard a WW II submarine: The ship's cooks were trying to bake bread one morning while the skipper had the boat doing practice dives, and whenever the boat readies for a dive, the crew seals all hatches and puts "pressure in the boat" -- increasing the air pressure throughout all the sailor-populated internal spaces to slightly greater than the typical ambient atmosphere at sea level, testing watertight integrity. On surfacing, this increased pressure vents suddenly when somebody opens a hatch for the bridge crew to emerge.

After the second batch of bread loaves were ruined when the sudden pressure change made them "fall" (go flat), one of the messmen passed word forward to the control room to have an officer let him know when they were finished the submerging-and-surfacing cycles for a while so the galley (the sub's kitchen) could complete the day's baking.

The thought of getting into that pool freaks me out 1026 more times than the Grand Canyon glass footbridge does. Seriously, I wouldn't go near that thing.

Cool post. But jesus am I in for some nightmares.

Scariest thing ever. Metafilter always outdoes itself in this regard.

pax digita: Almost as good as the missile silo, but not quite 33m.....

Dear gods of the deep... Reading the description on that made me gasp and suck in my breath just sitting here at my desk!

fluffycreature writes "My other question is how this was built. How thick does the concrete need to be at 90 feet to support this?"

For poured in place only thick enough to hold back the earth while the thing is being built. The pressure of the earth will provide a compensating force for the pressure of the water once the pool is filled. However probably the easiest way to build this would be with precast tubular sections (like sewer castings) that are lowered into an oversize hole and then backfilled. The precast sections would only need to be thick enough to support the sections above.

Also it's probably no accident the 33m section is circularish, that arrangement puts the concrete in compression from the external forces which is what concrete excels at.

Diving can make you lose weight without effort. It also increases libido on a intellectual level.

That explains a lot. I have always had trouble with my overactive intellectual libido after I dive. (Only half-kidding.)

Nifty. Although I'd prefer it a bit more murky.

They keep the pool at 30C which is nice and warm, good thing they are using solar collectors to heat it.

Smedleyman : As well as the aesthetic value, I'd imagine the 100% visibility is a handy safety feature ...

Yeah...but I like not being seen. 'Specially if I have my 'black lagoon' gear on. Works great coming out of water traps on golf links.

It's also nice that a restaurant like that would have self-selecting clientele. Nothing against you or anything, but I doubt very much you'd be there in the first place to have the panic attack.

In case anyone is looking, I happened upon some more pictures of the pool.
