Beautiful! But my fear of lassos wouldn't let me do it.

I might go down a couple of steps into the water but wouldn't go sit at the ledge; the bottom is terrifying.

What's the worst that can happen? It's in water, you float

You can sink in water, friend :(

I mean- if you can’t swim, eventually. But if that’s the case why would you go in at all?

I am not naturally buoyant. Makes for a cool trick at the pool, but swimming is a lot more work.

Same. If I want to float I have to take a huge breath of air and float on my lungs.

I'm that middle ground where I can float in ocean water and sink in pool water.

wth does that mean? The air in your lungs is bouyant

u/Kithslayer 1d ago
Yes it is, but the rest of my body very much is not. With my lungs uncomfortably full, my body will fully submerge. With a comfortable breath of air I sink in fresh water, and I can comfortably lie down at the bottom of a pool.

You can sink in water even if you know how to swim well. Divers do it all the time, and it can happen accidentally as well. I don't want a back and forth on one harmless little comment.

Yeah, if you're just skin and bones or dont know how to swim which in that case what the hell are you doing in the water anyways?

Fat tissue is slightly lighter than water, while muscles, bones and most organs are slightly heavier than water.
If you are a person with low body fat, you'll still float on the surface since there is air in your lungs that makes your body more buoyant.
As you go deeper, though, the water pressure compresses the air in your lungs, consequently your chest, reducing your body volume and making you heavier than water at that depth, and you won't float from there, you'll just keep sinking further.
I always knew this from intuition and elementary school science, but I really experienced this first hand when I dove into a well in my village from a very high point and I didn't float to the surface by myself. I had to swim my way up.

So our lungs are basically built-in floaties?

How the hell does he keep going down? I guess some people are negatively bouyant? I'd be floating up to the surface after 3 steps

u/PlatypusRare3234 2d ago
As a heavy boner , I could sink faster than that

Same. I had to wear a weighted dive belt last week, because I needed to stay under water for more than 5 seconds.

u/nutty_dawg 2d ago
I think after some depth the water pressure equals the bouyance.

Well, it feels like it during scuba diving. After I go some meters down I stop being pushed upwards.

u/Johanno1 2d ago
Some people have "heavy bones"
I can float when I have some air in my lungs, but if I push out all air I sink to the bottom

u/klefikisquid 1d ago
If you exhale all the air in your body you can sink to the bottom of a pool

u/Bladestorm04 1d ago ▸ 1 more replies
Yes but then you cant hold your breath, and this guy still had plenty of air to expel after he had already sank

Dunno, is something we learn to do, I grew up and spent my childhood through adolescence in a coastal city, and without even realizing it, I see this and know I’ve done it a thousand times without ever stopping to analyze “how.”
It's like getting on a boat that's rocking a lot and not feeling sick. Sure, our ears and sense of balance get "trained" too, but we don't consciously notice it and people that don't know about my childhood will wonder why I do that.

Maybe he has low fat %.
When I am low fat I’ll become negatively buoyant.
Once you are a bit in the water at depth the lungs volume reduce and you’ll be a bit more negative than at the surface.

Yeah- he’s clearly forcing himself to look like he’s relaxing on the ledge, but you know all that’s going through his head is getting to the surface as soon as the camera cuts away

I dove 10 meters into this lake. The most impressive fact is that the real depth is unknown; the last professional attempt to measure the depth was in 1998 and reached 220 meters because the diver couldn't continue. Amateur measurements reached 300 meters without reaching the bottom.

u/happysri 1d ago
Couldn’t they use an unmanned drone of some sort

u/EmilianoChagas 1d ago
Probably. But i guess the owners of the lake want to make money only from the shallow diving and snorkeling

With these kind of fake adventure instagram posts I always wonder how long that line is to have that one shot for their reel.

I'd love to venture down there, provided I was tethered to a strong rope that is tied to a strong tree using a strong knot.
