Hello there, Hello, Hello. It's me Josh, and this week's s Y s K Select is a little episode from two thousand twelve called Geysers Colon Nature's Innuendo. I thought of that title myself, and I still love it to this day, so I hope you enjoy it. It's one of those really cool Earth sciences bio geochemical ones that really get me jazzed, and I hope it gets you jazz too. Let's all get jazz. Welcome to Stuff You Should Know, a production of My Heart Radios How Stuff Works, Good Bloom, and welcome to the podcast. I'm Josh Clark. There's Charles W. Chuck Bryant, and uh, this is Stuff you should Know. Yeah, just a couple of regular guys are sitting around chat. That was good. I know, I genuinely didn't think you were going to say, guys, really a little um. This was a pretty cool article. I thought I knew a lot about Geyser's, but I did not know exactly what was going on there. Yeah. In fact, I was wrong on a couple of key points. Oh really, yes, which I will not point out. Oh come on, well, I thought they spit out lemonade first of all. Uh, and I thought there was a little guy down there doing it. Oh got lepre cons Yeah, yeah, that's what everybody thinks. I was wrong on both of those points. Do we have a geyser myth sound effect? I don't think so. Um does this count as weather? Now? This is earth science, biogeochemical processes. Okay, I just know what you're trying to be beef up our weather. Uh. This is not whether it's not weather, although it does begin with weather. Yeah, I mean when something precipitates, that's weather, and precipitation precipitates the explosion of a geyser, that's right. Uh chuck, Yes, I have no guys are introduction. Man, you can't blame me though, Like I looked, and there is really not a lot going on on geysers. I thought you might tell the story about the people in nineteen o three. He was going to, but I didn't want to just usurp it. Okay, but let's do that though, since you brought it up, Because I mean I thought about that too, I was like, whoa hang back, Josh hanging back? Well, apparently guysers can kill you. Um, and you know when you see something like old faithful go off. That's why you're three ft away watching it. Yeah, you know you're not gonna be on top of the thing. But apparently in nineteen o three in New Zealand, which is allowsy with geysers, um, some tourists visiting there got caught in a jet at uh wy man Wymani valley nice good and uh it killed all four people and carried them more than a mile away. Yes, that is sad. And after after we explain how guysers work, I think that will well we should mention that again because once I understood how guysers worked and I read that, I was like, those people met a terrible, terrible demise, like they that was terrible way to go. Yeah, I mean, it's tantamount to getting thrown into a volcano or caught in dropping into the cracks of an earthquake, and they're all kind of related, as it turns out, or being blood into death, which is not related. No, but it's pretty bad way to go to the geothermal earth properties. So um chuck geysers, as I learned UM from reading this article on how stuff works dot com um our beloved site, UM, are actually kind of fragile and there's not that many this this article, there's a thousand guysers roughly in in the world. And um, I read elsewhere that there's only about fifty geyser fields on the planet, and about two thirds of those have five or fewer guysers, which makes yellow Stone a pretty substantial repository of geyser and guys are related activity. Because when you're talking guyser, you you you don't ever just talk guys or you're also talking um fumer roles. You're talking hot springs, mud pots, steam vents, and all of them are based around the same thing, which is there's some sort of geo thermal activity that's relatively close to the Earth's surface, right, Um. And there's three components to a geyser um and they are water supply, plumbing system, and heat source. Yeah, and I'm gonna argue with fourth later on later though, I have to wait. I'm gonna call it. We'll just go ahead and say what it is, which is a remoteness, all right, and then we'll we'll circle back because detached from its family, right, it comes very remote. So a water supply, let's start there, because if you ain't got water, you ain't got no guyser. Yeah, and I saw in this article that um rivers can often um form the water or supply. I didn't. I didn't see that elsewhere. For the most part, from what I from what I can gather is that the water supply is um precipitation, rain and snow melt percolating through the Earth's crust over five thousand or so years, and then it trickles down to the point where it comes in contact with like we said, relatively shallow geothermal activity, usually very very young volcano volcano or volcanic activity, or very very old like on in the throes of death volcanic activity. Yeah. Um, and it can be anything from magma to um cool magma. But it's very hot rock and it's close enough to the surface that this water doesn't evaporate, it starts to trickle back up. Yeah. And when do you say close? Three miles down seems like a long way down. But if you're talking the planet Earth, it's nothing. That's pretty close. Yeah, if you're talking magma, it's pretty close. We're talking techtonic plates, it's pretty close. It's closer than you on it to be pale. It's a go ahead, okay, Number two of the plumbing system, right, very important. Um. The plumbing system is a series of fissures that run miles beneath the surface. And one important aspect of these fissures is they're basically sealed shut with silica from rhyolite. It's volcanic rock, um and like these minerals have sealed this rock shut. Right, So, like really important part of it. That water that's percolating down, when it heats up and starts to travel back up, it takes that silica that rhyolite with it, and then it just kind of acts as a ceiling along these pipes over five hundred thousand years, however long it takes for it to go back up. It's it's ceiling and it's making it water tight. Well yeah, and I imagine I didn't read this, but I imagine that this kind of activity happens elsewhere on the planet, but it's not sealed up, so it just disperses, right. Yeah. Because one of the key ingredients of a guy's or is pressure, high pressure, that's right. And to get that pressure in these pipes, you have to have ryolite coated sealed pipes. That's right. Okay, so there's the plumbing system and it can the plumbing system varies. All guysers are different. Sometimes it's just like a huge, long vertical chaft. Sometimes it binds and turns and winds around. Okay, so this is this is something that actually differentiates guys are from a hot spring. So a hot spring is just like a like a long vertical chaft coming from hot water um up to the top, but there's no obstruction. What makes the guys or a geyser is the fact that there's an obstruction in the plumbing right where the hot spring water can just move freely up and down. There's there's just free exchange and you soak around in it like a big lazy wall rush. But there's no pressure. With the guys are, there's some sort of obstruction where either say, the water on its way back up and there's this wide pool that bottlenecks at the top, so now you have pressure. There's a bunch of different pipes feeding into one pipe and they all connect to the same place another bottleneck or this this pipe of water is so wide and so deep that the pressure from the water above the water at the bottom is so tremendous that for all intensive purposes, it creates a bottleneck just strictly out of pressure without an actual obstruction. Yeah. Just the weight of the water itself is so great. So we have a water supply and a plumbing um system that is sealed with rhyolite which makes it water tight and pressurized, and then some sort of means for pressure to build. Yeah, and uh, I guess we can go ahead and liking it to a pressure cooker now, so you understand we're talking about if you've ever cooked with a pressure cooker at home, or if you've ever eaten it Chick fil A and eating their delicious pressure fried chicken. Is that how they do it? Oh yeah, let's explain pressure. So that's why there so juicy man um. So water is standard water is just gonna boil it like a hundred degrees celsius in the fancy French water. Um, if you're if you're cooking with a pressure cooker, which means you know, the littue sealed shut it lets out some steam or else it would explode obviously, Um, it will actually take a lot more energy to boil and bubble up, which means more heat and so you can actually cook in a pressure cooker at like twenty five degrees, right, because it's just substantial for under that pressure. It takes a lot more for what it was boiling water. But it's like air bubbles forming and rising to the top. When the pressure is too great, it can't boil. So the boiling point rises, right, Well, it boils, but it won't it can't evaporate. Well, no, it can't. It can't form the bubbles that carry to the top, so it can't actually boil. So it's just sitting there in this high pressure environment at high higher than boiling point temperatures, and the same things going on in a geyser. Right, You've got the obstruction, you've got this heated water, and you have a tremendous amount of pressure because again we're talking about miles deep, um, and there's that's quite a bit of pressure at the bottom the water at the bottom, and it's getting hotter and hotter and hotter. Yeah, like, um, I mean, I guess it depends. But for guys are to form and start, they think the oldest one is between five thousand and forty years old. So yeah, so it takes a little while because you know, the plumbing has to has to steal up and everything. But as that pressure builds and then that heat um increases, you can reach temperatures of like four or five degrees fahrenheit of this water and it's still not boiling, right, that's right. And then eventually it does boil. It overcomes that pressure threshold. Well, it finds its way through to to the escape route, which is the top of the surface, and it'll just and that's not the eruption, it'll just scored a little bit of water out. You'll go and think, wow, that was a big relief, and such a big relief that, uh, the steam all of a sudden expands to fundred times the volume of the water. It's like if you're ever boiling, uh you ever steam vegetables in your house. The best way to steam vegetables is you don't just set it on a massive boil and cover it up. You get it to that massive boil and then you turn that heat down low, and all of a sudden, that pressure drop creates like massive amounts of steam. Right. And the reason why is because when you increase pressure, you increase the temperature. That's the boiling point of water. If suddenly you have that temperature still, but the pressure decreases that that water and this guys are just flash vaporizes. And because there's a lot more volume to an equal amount of water and steam, that steam, like you said, expands to what times of volume? Yeah, and there's your guys are how Yeah, it's that's all of a sudden, all the steam in the water just gets shot out. Depending on what kind of guys are it is, it's going to take different formations and be different heights and last different amounts of time. But um, it'll keep going until it either runs out of water or it cools down enough for it just start all over again. Yeah, and then it just starts all over again, which is how you get something like Old Faithful. All right, that's right. Once it once it releases that um that pressure and it shoots out, it's the whole process just begins again, and you have, um, guys are's like Old Faithful that erupt like on a pretty regular schedule. I think it's between like sixty and eighty five minutes or something like that. Well, I've got the new schedule schedule because it's been it's been happening with greater with less frequency in greater power in recent years, I think it's said since two thousand UM and it's a bimodal. They call it bimodal. And if you're going to Old Faithful in Wyoming, Um there are generally two eruption durations now, either a long one which is over four minutes, or a short one, which is about two and a half minutes. And if you have just missed the short one, there'll be about an hour before your next eruption. If you have just missed the long one, then there's gonna be about an hour and a half until the next one. But either way, it's it's worth sticking around for it. Yeah, And it's funny if you go to the page and there's obviously a webcam up where you can see it and stuff, but that's not as fun. But if you go to the web page and they ask for tips on you know, seeing it, they say, well, if there's a lot of people sitting around on the benches, that means there's one upcoming. If there's a bunch of people getting up and leaving, that means it just happened. It's like, wow, really, yeah, that's the best you can do. That sounds like um, like hippie park ranger logic exactly like um. Okay, so, uh well, I guess we're onto like famous geysers, right, yeah, Actually quickly I mentioned I teased about the fourth um thing remoteness. Apparently, in the last fifty years, uh, producing energy with geo thermal energy production has increased so much that it's affecting geysers, and so being remote is now believed to be one of the requirements to be a geyser, because geysers are vanishing because of man. Because so I was trying to figure out this out, maybe you can help me. That's because we dig down to these this this um, these geysers of this geo thermal activity, and in doing so, are we creating like a release valve so the pressure camp build as much I think so. I mean they're using it to spind turbines to create energy. But I know you can also have like a geo thermal system in your backyard, which I don't think uses I don't think it like creates steam. So I feel like what we're doing then is creating artificial geysers, like eating an artificial pipe to let steam out, which would impact any natural guys activity. I because like we said, they're very fragile. Earthquakes frequently um cut them off. They also bring them back to life too. Yeah, that's true. Like there was one called the Stroker Geyser that that would be str o k K you are, yeah, and that's stroker like stroker race right right. So Stroker geyser um is after the Icelandic well, Stroker is after the Icelandic verb to churn, and actually geyser's after the Icelandic verb um to gush. So this is all very Icelandic in origin. But that would be g e y s i R geyser okay in Icelandic. Sure, I own how Buyork pronounces guyser. Have you seen Kristen Wiggs impression of her? Huh that's really great? Um okay, So the Stroker Geyser was actually um it was enacted in nine um because of an earthquake, and then another earthquake hit in and it became inactive. It went dormant and the local said, we got to get our guys are back, man, it's all blocked up. So they cleared it off and now it's running again. I bet that was probably dangerous work dangerous um. Another way to that humans are impacting is a mineral extraction. Apparently in two thousand three, Uh, they were extracting minerals in Chile, the second largest geyser field in South America, and it killed it basically from extracting golden stuff. Because basically they mess with the plumbing and then you're finished. Because it's like you said, like, um, in a pressure cooker has that little steam val so it doesn't explode. The guys aren't supposed to have that, right. If they have that, they just don't go off. They're like, well, fine, I'll just let some steam off and um, um, that does happen. Naturally, there are steam it's located near geysers. Um like yellow stones. Like we have ten thousand um geo thermal um what is the word they use, Uh, basically different things. We have ten thousands of your thermal different things. Um. But the vast majority of those are like steam vents. Oh they're man made. No, they're they're natural. Like. Oh, they're like little steam releases that come up through fissures. Okay in the earth. I thought you meant we put those in to make old faithful like safers. No, they happen naturally. Um, but I think it's the same thing as drilling a hole down to a geothermal um different thing and uh and tapping it to run a turbine. Okay, at least you didn't say interesting. Interesting, man, this stuff is very interesting. Um, old Faithful is a cone geyser? I'm not sure I understand the difference? Is it the is it the good difference? Is it the outlet like the shape of the thing above the earth. Yeah, So with the cone guys or, the rhyolite bubbles up and enough over time that it builds up and it forms a little cone and that's what the guys are shoots out of. And normally with the cone guys or you have a big stream going jet going into the air like hundreds of feet. That one in um in uh New Zealand, the Wyman ge geyser. Um, that one streamed seventy ft into the air and for those of you in New Zealand, that's four hundred fifty that's a world record, right, yeah, nineteen oh two, Yeah, before it killed people, right, and then it went dormant in nineteen o four because of a landslide, which makes me think like this thing's coming back. I just gotta bubble back up and then shut down right afterwards. Yeah, it's really had a really chaotic to your career. It's like a rock star that overdosed on heroin or something. Um. But anyway, as I was saying, um, the cone shoots a jet into the air. The fountain, Um, it shoots in a much more like chaotic streme whatever. But it doesn't come up from a cone. It comes up from a pool. So at the surface, the geyser goes into a pool of water and then that will erupt out of the water, and that would be the grand geyser. Um, the tall that's the tallest regularly erupting guys are on the planet. And that is also a yellowstone. Yeah, the tallest in that it shoots up in the air. Yeah, two hundred feet in crazy fountain e hard to predict fashion. Yeah, which is pretty surprising too, because the cone geyser shoots a jet straight up in the air, and this fountain geyser is still beating the average one. Yeah. Could you imagine if it was a cone geyser, it would be mind blowing to the moon. Uh. You mentioned the stroker ace geyser the steamboat guys are. Yeah, apparently can choo water up to three hundred feet, but don't bother stopping by because it hasn't happened for fifty years. It can go fifty years between. It's finicky. Yeah. Um there's also the geyser. We to the o G geyser because that's where the word came from. It's a geyser in Iceland. It was discovered in um so it's the oldest known guys are on the planet. But they took some samples of the silica that forms the cone of the castle guys are in Yellowstone. That's the one they think is five thousand to forty thousand years old. Apparently silicon dating can use some work. I did see one interesting little and it wasn't a joke. It was almost like you could hear science guys laughing about it. Though. You geysers are always called geysers, even if they quit erupting, but that ceased to make seats to be a geyser at that point. But once you have erupted, you're always called a geyser. The cone formerly known as geyser. Yeah, that's what I would call it. Shameful, uh, let's do you know that whole story about Prince doing that about changing his name. No, I never knew the story behind it. So he was locked in a contract with Sony that he didn't like, and Sony basically said, you can't release an album as Prince. Yes. And but also that had something to do with him acting basically crazy, like he acted crazy on purpose to get out of his contract because there was some sort of clause where like if he was if he went nuts or whatever, it would avoid his contract. So he did that, and he had that font release and I remember he released it to the media like, um, his little symbol yes to as like a font add on so you could just print the symbol when you were writing about him. And his contract with Sony was either avoided they gave it up or whatever. But he was basically like, I'll show you crazy if I need to get out of this contract. Boy. One of the best concerts I've ever seen. Oh yeah, I'll bet. And I don't even think I put it in my top five when we had that listener mail that time, but probably forgot. It's probably in my top five. I would like to see print sometimes he brings it he um, he bought you me a bottle of water at um a Miles Davis show at the Cotton Club. Really wow. Her friends came up to see the lemon Heads and she's like, yeah, I'll go with you, and then found out that Miles Davis was playing. It's like, I'm gonna go over here, bottle of water, Evan Dando, Miles Davis exactly. Let me think about that. Sorry, e d um So that's uh, that's print. Oh yeah, and guys, oh yeah, guys are too. Um. If you want to learn more about guysers, you can type that word g E Y S E r S. That's the English spelling. We didn't do it icelandically. Um, but you type that in the search bar at how stuff Works dot com and it will bring up this fine, fine article. And I said search part host of works dot com, which means it's time for listener mail. All right, Josh, I'm gonna call this, uh given a local Brooklyn night, a plug for his election. But that's not how it started. Okay, that's kind of a complicated title. Um, guys who just listen to your podcast How Labor Unions Work, And I want to thank you for trying to give a very balanced, uh story to what is a very complicated and contentious subject. As a former New York City union organizer, so this guy was the real deal. I am very familiar with the arguments against unions, but I truly believe American workers in the American economy are better off with unions and without when unions are strong. Typical union organizing when unions are strong, there is some counterpoint to this total acceptance of rampant greed that was essentially the cause of the financial meltdown in two thousand and eight. At this point, with unions at their weakest and a half century, we average Americans are being held hostage by operations. This is what he says. Um, I have to say. In my line of work, violence was not the norm, but intimidation by the employer was constant. They did everything from threatening workers with being fired, lying to them and telling them they did not have collective bargaining rights, to telling them the union would only steal their dues and not get them a good contract. The deceptive HR person right there. Yeah. Or they would tell workers, um, they would work out individual deals with them if they would vote against the union, like trying to Yeah, that's pretty pretty, Harry. Even once when we were organizing at a Catholic hospital, they told the workers they were going against God if they tried to organize. Yeah, can you see like those priests like union breaking cracking heads with metal baton. The only problem I had with your podcast was the lack of coverage you gave to the triangle shirtwaist fire. We mentioned that. He said it could have been none more. He said it could deserve its own podcast. Well, that's true, we mentioned it. He said it was one of the deadliest industrial accidents in the United States history. Last year, hundreds of people came out to commemorate the one year anniversary remember of the lives lost due to lock stairwells and exits that fire was a major turning point in labor conditions in New York City and around the world, as well as bringing light to women's terrible working conditions. And I wrote him back, and it turns out, uh A day e d is his name. Fox is running for Brooklyn City Council. I said, you know what, dude, we'll plug your campaign. Uh www dot e d E f o X dot com, ad a fox dot com and good luck in your bid. For city council in Brooklyn. Yeah, if you wear um sunglasses with Neon arms on them and into like your pro union, I would say, God, vote for this. I think we can help garner you a little bit of the hipster vote maybe, since we are both aging hipsters. I not a hipster, dude, I am not a hipster, and I've maybe aging, but I'm not a hipster. Well you look a lot more like a hipster than you used to. Well if you, uh, I guess if you have a political campaign you're running, Um, we want to hear about it. We heard from another guy um in uh was it in Maryland, a state legislator. He's a he's a legislator for Maryland who was writing about human trafficking. That's right. Shout out to that guy as well. Um, but if you are a politician that listens to stuff, you should know we want to hear your viewpoints. Let us know what you gotta say, how we're helping you, how we can help more that kind of thing, you know. Um, you can tweet to us, just please don't send us a picture of your junk like other politicians. UM to s y s K podcast.
