Scuba Diving - Under the Sea Theme

Andi 0:01

I mean, lot. It's one of those things where it's like, is that a little, is that

Sups 0:05

that a lot? I dunno, it's not a lot.

Tanner 0:09

If you went below 20 feet, you would die. Oh God.

Sups 0:13

He didn't have to pee or poop.

Tanner 0:15

I, it doesn't

Andi 0:16

he's

Sups 0:16

pee ocean, but how? Why?

Andi 0:20

the, it's not astronaut, it's just the ocean. It's a giant

Sups 0:22

toilet.

Andi 0:24

You could

Sups 0:24

have just did the

Andi 0:25

dogs scuba dive hello and welcome to this episode of The Eye Shed of Known podcast, the trivia podcast that can't be trusted. Each week, our Quizmaster presents you with four big facts on a topic, but one of those facts is a lie. We're starting our new theme for May. We are Under the Sea. Our first Quizmaster is Tanner.

Tanner 0:45

Hello.

Andi 0:46

and he's going to be presenting us with four facts about scuba diving, but one of his facts is a lie. So join me, Andy, and our other host soups in figuring out one it is.

Tanner 0:58

I think we should dedicate this episode to two of our listeners, Wanda and Mike. They're noted scuba divers, they're big fans of the

Andi 1:06

They are.

Tanner 1:07

They've been requesting scuba diving for a

Andi 1:09

time. They really have, and they actually are patrons on rep Patreon, so

Sups 1:13

a special shout out to them. Yes, yes.

Andi 1:16

I'm afraid of what the low hanging fruit is, cuz I think I know what it might be and I don't know the

Tanner 1:21

Ooh. All right. What does SCUBA stand

Andi 1:24

Yeah, that's exactly the, that's exactly the question. I thought it

Sups 1:27

it yeah.

Andi 1:28

I think the U is underwater.

Tanner 1:30

Yes.

Andi 1:31

Breathing apparatus. so it's underwater breathing apparatus in the last three letters. Yes. That's uba. Uba, what's the

Tanner 1:38

It's hyphenated.

Sups 1:39

it's hyphenated.

Andi 1:40

Okay, so it's like a single word.

Sups 1:42

Yeah.

Andi 1:42

I think it's something like, it's like scantily clad underwater breathing.

Tanner 1:46

ever.

Andi 1:46

Oh,

Sups 1:47

you Wait, wait. I, I wanna crack. I wanna have a go at this. S C S C suspended

Andi 1:53

container

Sups 1:54

suspended container, underwater breathing

Andi 1:56

apparatus. Apparatus. Yeah.

Sups 1:58

Wow.

Tanner 1:58

Close.

Sups 1:59

No, you're not suspended. You're actually wearing it. So, Yeah.

Tanner 2:02

how else could you dive,

Andi 2:04

Like what's one of those old timey helmets? Yeah.

Tanner 2:06

And Do you know how those

Andi 2:07

work? No. You know,

Tanner 2:09

don't, they were connected to a boat via a hose. but these scuba tanks don't have a hose

Andi 2:15

connect I, so

Sups 2:15

Right.

Andi 2:16

like self-contained, underwater breathing apparatus. Nailed it.

Tanner 2:20

it.

Sups 2:20

We did

Andi 2:21

I still think scantily clad is a better

Tanner 2:24

like that a lot.

Sups 2:25

Wow.

Tanner 2:25

Scantily clad, bikini is required.

Andi 2:27

Yes. I knew that was going to be the question and I still was like, I don't know. I have no

Tanner 2:33

idea. You figured

Andi 2:34

it out We

Tanner 2:34

I love it. Nice. That was a good episode. That's a wrap. Yeah.

Andi 2:39

So

Tanner 2:39

Fact number one. Since 1967, the Professional Association of diving instructors. Has issued 29 million scuba diving certifications.

Andi 2:50

I mean, right off the bat, before he even says anything, if it were to be a lie, it'd have to be an order of magnitude. So it'd have to be like 2 million or 290 million, but Sure.

Sups 3:00

Okay. But I think 29 million sounds like a good number because I think majority of that I would credit it to Instagram because now I think people, you know, because, yeah, this has become like a hobby. Like, I'm going to this island to get my diving certification. I'm going to Thailand, or I'm

Andi 3:17

Yeah. But I feel like that was a thing way before Instagram. Yeah. I lived on an island where people did scuba certifications all the time. Like this was pre-Instagram and he's talking about the sixties. Mm-hmm. Though it does seem like a pretty big number. I guess when you're talking about over 60 years mm-hmm. that's what, 500,000 people per year? Yeah. That's a lot. seems high. getting their certification.

Tanner 3:41

Now it's over a million a year.

Sups 3:44

Yeah.

Andi 3:44

That seems too

Sups 3:46

high. Yeah. Hmm. What else could you tell

Andi 3:47

us about

Sups 3:48

it,

Tanner 3:48

Yeah. Patty or the Professional Association of Diving instructors? began in 1967 because there was really no official certification. And it operates in over 180 countries around the world. They have specific dive centers with big pools that you can learn in, and certification takes about a week. Mm-hmm. and certification lasts a lifetime. right? Yeah. exactly. So there's open water. Yeah. Which just means you can scuba dive and then there's advanced open water.

Sups 4:17

So it's very similar to like the wine Yeah, sommelier. Like the W S A T, like level one, level two. Like how do your wine courses,

Andi 4:26

Sure.

Tanner 4:27

Yeah. You

Sups 4:27

Certified.

Andi 4:28

No idea what you're talking about. Yeah. yeah. But the difference is anybody can just drink wine whether they're certified or

Sups 4:34

Mm.

Andi 4:35

so, I still think the number seems 29 million. Really

Sups 4:38

Really high. Mm-hmm. do you think it's high in the range of like, you think it's like 2 million, 3 million, what range are you thinking?

Andi 4:45

even 500,000 sounds high because, okay, it's lifetime, right? So that means we have to have every year on average 500,000 new people. Right? That's the population of like a whole city. Every year. That is so many people. I don't think that

Sups 5:00

That many people or

Andi 5:02

dude, I know it's worldwide. Yeah, of course. You know, I would believe 29 million people have dived.

Sups 5:09

Okay. didn't you just say that now it's actually 1 million per year average people are getting

Andi 5:15

that's. That's a lot. Okay. And that wouldn't take very long before you'd have like a huge population where like the whole planet Yeah, Exactly. Yes, exactly. And like you would like, you would know

Sups 5:27

Yeah. Yeah. Mm-hmm.

Andi 5:29

Well, I have to hear more, but I'm like, I'm

Sups 5:31

I'm

Andi 5:32

like very skeptical. Yeah. I would not take that oxygen tank full of with that. fat to down under water with me.

Sups 5:38

Okay,

Tanner 5:39

perfect. Let's talk about oxygen tanks. Fact number two. you're welcome. The gas in recreational scuba diving tanks is 21% oxygen.

Andi 5:48

like the atmosphere, just

Tanner 5:50

like the air we

Sups 5:51

Yeah. Okay.

Andi 5:52

Okay. Alright. Backed over. Fact number three.

Sups 5:56

So there's also mix of other gases.

Tanner 5:58

Yeah.

Sups 5:59

What other gases are there? Nitrogen. Okay. So it's like

Andi 6:02

atmosphere. Okay. So couple things. One this would again be an easy place to lie cuz you just say like, it's the same as the atmosphere. Mm-hmm. So I think one of the things about this as weird is if we didn't think of oxygen tanks, like for people with health issues Mm-hmm.

Sups 6:18

The ones in hospitals are almost pure

Andi 6:20

Right. That's what I'm saying. So I guess maybe he's playing on that. Like it's called an oxygen tank. But why isn't

Sups 6:26

it mostly These oxygen tanks are not different.

Andi 6:29

I think they're different. probably we call them oxygen tanks, but from what Tanner's saying, it's actually just compressed air. You're

Tanner 6:37

Yeah, If you went diving with the tanks that they have in hospitals, you explode. If you went below 20 feet, you would die. Oh God. Because you would absorb more oxygen than your body can

Sups 6:47

handle Just the

Tanner 6:48

change. So you could dive with pure oxygen, but if you went below about 20 feet, You get sick.

Sups 6:57

Okay. too much oxygen is not good for me. Exactly. Oh

Tanner 7:01

yeah. It's toxic at high percentages.

Andi 7:04

So it's just, it's actually compressed air. right? Which I guess kind of makes sense. Our lungs and our bodies are perfectly adapted to breathing atmosphere,

Sups 7:14

and you are breathing out carbon dioxide underwater.

Tanner 7:17

Yeah. So there's really two kinds of scuba. There's one where the air goes into the water. Okay. And there's one where you rebreathe it, so it filters the carbon dioxide and you breathe the air back in. But mostly you let out bubbles. Yeah, That's CO2

Sups 7:30

one, that's the, yeah. Okay.

Andi 7:32

Okay. I mean, yeah, this fact doesn't sound sketchy to me other than we call them oxygen

Sups 7:38

Right.

Andi 7:39

so then shouldn't

Sups 7:40

they That's where the name is. Okay.

Andi 7:42

But like misnomers are a thing

Sups 7:44

All right.

Andi 7:45

I know that like oh two is volatile, so like so it would make sense that you don't wanna bring it underwater mm-hmm.

Tanner 7:51

Fact number three. The deepest scuba dive was over 1000 feet or 304 meters.

Andi 7:58

I mean, lot. It's one of those things where it's like, is that a little, is that

Sups 8:03

that a lot? I dunno, it's not a lot. 304 meters. Like if you're talking deep and that's not recreational

Andi 8:09

I would think that, yeah, like a thousand feet, 300 meters. I mean, you would have. Pretty significant things happening

Sups 8:16

to your body.

Tanner 8:16

The record is held by Ahmed Gober from Egypt. Okay. Who dived 332.35 meters or 1,090 feet in the Red Sea. In Hab, Egypt. Okay. In 2014, it took about a decade of preparation. the dissent took about 15 minutes. The ascent took 13 and a half hours. Mm.

Andi 8:40

Wow. Because it messes with you so bad.

Tanner 8:42

Fine. Yeah. Because he had to slowly ascend to make sure that he didn't get the bends

Andi 8:47

have been so hungry. I can't go like two hours without eating. you

Tanner 8:51

could

Sups 8:51

You

Tanner 8:51

underwater,

Sups 8:52

but How,

Andi 8:54

why

Sups 8:55

He didn't have to pee or poop.

Tanner 8:57

I, it doesn't

Andi 8:57

he's

Sups 8:58

pee ocean, but how? Yeah, I'm I'm trying to think of the logistics. Yeah. Okay. In a separate pouch or in

Andi 9:07

the, it's not astronaut, it's just the ocean. It's a giant

Sups 9:10

toilet. Yeah. But you're gonna be still swimming in that?

Andi 9:13

Yeah.

Sups 9:13

Okay. Mm-hmm. ocean. Yeah. Okay. I think this checks out only for the fact that I know that Egypt is big on diving. Yeah. It's a very big thing. Like Squash and diving are like, for some reason very big in this country. So This diver is from Egypt. I want to believe that this is true.

Tanner 9:30

Mm-hmm. so after 10 meters of depth, pressure has increased. Another atmosphere,

Andi 9:35

Uhhuh, it's basically doubled.

Tanner 9:37

right? So 10 meters, it doubled he went 330

Andi 9:41

Right. Did he have to wear a special thing? I mean, imagine it's cold, so he'd have to cover his whole

Tanner 9:46

Super cold. the photos just showed him in a wetsuit. Mm-hmm. But he had a whole team of technicians and divers and medical support team already for him. Wow.

Andi 9:54

Wow.

Sups 9:54

was he in contact with other people when he was doing this type?

Tanner 9:57

I don't know. I think he probably had a

Sups 10:00

That's also pretty cool that radio can work so deep under Yeah,

Tanner 10:03

The, the Red Sea is almost 10,000 feet deep. He went a thousand

Andi 10:08

So he's only going like a 10th of the ocean. Yeah, but still like we're talking about the human body. Yeah. Like it's not a submersible like a machine. This is his. Body, there's not really much between him and the ocean. So, yeah, I mean, it's impressive. the only lie, I could think it would be like somehow magically This was free diving and that scuba can go way deeper, but like, I don't

Sups 10:31

know. Okay. You know what

Andi 10:32

I mean? Because like how is, how is this a lot? Yeah. In technical or, or No, it's some other guy in some other place, but I don't know why he would think we would know that. Yeah. So I feel like we have to believe

Sups 10:43

Yeah. off the tree so far, I think I believe this

Andi 10:46

one. Yeah. This The most. believable,

Tanner 10:48

All right, so that was the deepest human scuba dive. Fact number four, the deepest scuba dive by a dog. Was 130 feet or 40 meters.

Sups 10:58

Why? Why? Why? One question. Why?

Andi 11:04

You could

Sups 11:04

have just did the

Andi 11:05

dogs scuba dive and I would've been

Sups 11:07

we'd have a debate. Yeah. Okay. Okay. Now we have to go back to the basics. Yeah.

Andi 11:12

I

Sups 11:12

know that dogs actually scuba dived.

Andi 11:14

dogs can scuba dive things I learned today that's way more interesting than any of the other things.

Sups 11:20

What kind of dog

Tanner 11:21

It was a Labrador retriever mix.

Andi 11:24

Naturally. Okay. So This's gotta be American then, because that's the most American dog

Tanner 11:28

ever. Yeah. Is American in the Cayman Islands.

Sups 11:31

Okay, sure.

Andi 11:32

What's the dog's name?

Sups 11:34

All right. So shadow, she went,

Andi 11:36

how did they make a little doggy tank? They made a little doggy mask. is this ethical? Like you can't explain to a dog what it's about to happen to it.

Tanner 11:44

That is exactly my issue with it.

Sups 11:47

with it. Yeah. Yeah. And how does the dog know that it has to like, go down, come up, Like you know

Andi 11:51

doesn't know what you're doing to it

Sups 11:53

Was it guided? Was there rather human

Tanner 11:55

being? Yeah. So the owner, he loves to dive. Okay. He dives all the time. Okay. And Shadow kept trying to join him when he would dive. And so he's like, I really wanna bring shadow with me. How can I bring her scuba diving? So he made a plastic globe helmet? Correct. That goes over her head So her helmet is connected to his tank with a hose. Mm-hmm. So technically it's not self-contained, you know, but so Yeah, exactly. Yeah. She only goes with him. Yeah. And she's dived over 30 times. he says that she wants to do it and it's on her free will. But Dogs can't really consent. They can't tell you if they run out of oxygen. They can't say, I don't want to be down here anymore.

Sups 12:36

Are there like dog specific signs? Did she,

Andi 12:39

Hey look, there's

Sups 12:40

a

Tanner 12:40

shark right here.

Andi 12:41

Yeah. Yeah. yeah. I guess she could probably bark within her little helmet. Yeah. Yeah. full of compressed air, not oxygen.

Tanner 12:49

that's

Andi 12:49

Apparently.

Tanner 12:50

Yeah.

Sups 12:51

Wow. Okay. Shadow.

Andi 12:53

Shadow the dog.

Tanner 12:54

Yep.

Andi 12:55

Wow. do we believe this isn't, you know, Tanner made up an entire idea. He's like, what do I lie about? A dog that I think,

Sups 13:02

well I think, you know, it's not outlandish to think of if a dog can go to the space.

Andi 13:08

Exactly. A Yeah, the

Sups 13:10

as well.

Andi 13:11

I think what people forget is that dog didn't come back

Sups 13:13

Right, right.

Andi 13:15

from space like it. Yeah. She

Sups 13:17

She died. She died.

Andi 13:18

Yeah. Yeah. She went up there and died. That is true. Everyone's like, oh, this hero. She died, you guys, she didn't make it back alive.

Sups 13:26

Yeah.

Andi 13:26

So like that's a bad

Sups 13:28

Okay. Sorry. But, but you know the context, if it can

Andi 13:31

can go up, it

Sups 13:32

go down,

Andi 13:33

Sure. Yeah. I mean, it seems really cute. Like I could get behind, it's like, oh yeah, you're, a puppy wants to come with you. That's cute. How deep was it again?

Tanner 13:42

130 feet or 40 meters.

Sups 13:45

Okay.

Andi 13:45

So like That's quite a lot. Yeah. I mean, we know dogs can swim, So like realistically they can probably dive a little bit themselves. Mm-hmm. But that seems a little. Weird that she like, okay, she likes to dive, but detainer make that up. I really doubt it. That'd be pretty ridiculous. Yeah, I'd be pretty impressed if he's like, yeah, I made that up. I feel like if Tanner were to make it up, it would've been a cuter name. for a scuba diving dog. so those were some seriously cool

Sups 14:12

underwater

Andi 14:14

breathing apparatus. Anyway, Those are some interesting facts about scuba diving that you just told us, but one of them is a lie, so can you please repeat the four facts and then we will take our guests at which one it is.

Tanner 14:25

okay? Fact number one. Since 1967, the Professional Association of diving instructors has issued 29 million scuba diving certifications. Fact number two, the gas in recreational scuba diving tanks is 21% oxygen fact number three, the deepest scuba dive was over 1000 feet or 300 meters. Fact number four, the deepest scuba dive by a dog was 130 feet or 40 meters. One of those is a lie. If you need to come up for air, that's okay.

Andi 15:10

I'm gonna change the meter on your tanks

Tanner 15:12

oh, no,

Andi 15:13

actually run

Tanner 15:13

no.

Sups 15:14

make it 25%.

Tanner 15:15

Oh, no.

Andi 15:16

All right. So which one is the lot? So I think I'm gonna stick with number one. Yeah. Because I just think that number sounds wrong. Mm-hmm. that's a shockingly high number I think. I mean, yeah, it is over 60 years, but like it's, Yeah. Yeah. yeah. The thing about the compressed air versus oxygen, I mean, I could just be wrong. We could just be wrong about that. And that would just be like a, that's like a very, like black and white. like, nope, you should have known. And then I would be like, yeah, I should have, but okay. Mm-hmm. the deepest dive, I think that also there could be a lie there. Yep. But I don't

Sups 15:47

think so. Mm-hmm. So,

Andi 15:48

and I'm not gonna touch shadow.

Sups 15:49

shadow. yeah. So we, we leave Shadow Out Tree is the one that I believe the most. It's between one and two. You're going with one, which I also think is the light, but I think I'll pick two because I think maybe it's not like a direct replica of the atmosphere in the tank. Maybe there is like something, because you're underwater, there is like some sort of adjustment.

Andi 16:10

All right. I think she's compressed. air

Sups 16:12

Yeah.

Andi 16:13

I'm gonna go with number one, but I do think number three could be hiding

Sups 16:16

some. Okay.

Andi 16:17

Okay.

Sups 16:17

I'm gonna go with number two.

Tanner 16:18

Number one and number two. Okay.

Andi 16:20

Yeah, we kind of also did number three. We're guessing the first

Sups 16:23

three apparently.

Tanner 16:25

All right. The lie is shadow, yes. Fact number four. The deepest scuba dive by a dog was 13 feet or four meters.

Andi 16:35

Oh, but it, That's so it was the way, I thought number three

Sups 16:38

the live kinda

Tanner 16:39

reverse Yes. like,

Andi 16:40

She doesn't go that far down.

Tanner 16:41

Exactly.

Sups 16:41

Yeah. Like 40 meters is a lot.

Andi 16:44

I guess I just really didn't even like consider the depth. I was just like, whatever. Like that's not gonna be the library, because Yeah, when didn't really start talking about depths, They start to just kind of be a

Sups 16:54

lot. but Hang on. 29 million is true.

Tanner 16:57

true. That

Andi 16:58

That is insane. That's A lot of people.

Tanner 17:00

Yeah. It's so many people? Well, there's over 6,000 diving centers run by Patty around the world, So many people are getting certified.

Andi 17:09

you rich able-bodied people doing this

Tanner 17:11

that. Yeah. But If you got certified your license to about 18 meter depth and the maximum for recreational is about 40 meters. So shadows definitely not going that deep. She only goes about four meters.

Andi 17:25

Okay. Little baby dog. also think like, how deep could a dog naturally dive? what was it,

Sups 17:31

feet. 13. 13.

Andi 17:32

Could a dog just do that on its own? Maybe Yeah. I, guess I'm just kinda like, if you think about like a 13 foot pool That's not even that deep of a pool. I guess if she hated it, she could very easily just go back

Tanner 17:43

up. Yeah, exactly. yeah,

Sups 17:45

she feel,

Andi 17:46

so I should have. known.

Sups 17:47

I should have known.

Andi 17:48

Thanks for listening to this episode of the I Should Have Known podcast. We'll be continuing our under the sea theme for the rest of the month, and as always, thanks. Like when James Bond is like, harpooning dudes underwater.
