This sounds crazy, but it's true. There are lakes in the world that randomly explode, and it works in much the same way as soda cans, but on a massive scale, and cause massive death and destruction. They're called limnic eruptions, and they're super weird.

I've never done diet coke and mentos, but when I was in grad school a couple of us put some liquid nitrogen in a 2 liter bottle and left it in the middle of the park at the center of campus. To be fair, we made sure no one was around, but yeah it was not the wisest thing a bunch of grad students have ever done. The cops that stopped by when they heard the explosion were unamused but thankfully didn't haul us in.
and here i thought dry ice in a closed bottle was dangerous LOL
Diet coke doesn't use HFCS or sugar. They use an alternative so they can call it "diet".
@@Return_To_Sender yes. It's a calorie free alternative, which is what makes it diet lol
@@Chrishelmuth1978 "Calorie free" is marketing BS. The sweetener alternatives they use are just as bad, probably worse in fact, as just using sugar. It's not any healthier to drink diet soda than it is to drink regular soda.
Sounds like the MRE bombs we used to make in the Army. Throw that bottle in the trash dumpster and BBOOOOOOOOOOMMMM! Our First Sergeant was unamused.
There's a phenomena called "olfactory fatigue" which is when you smell something for long enough your nose stops smelling. Not permanently, just temporarily until your removed from the smell and your nose readjusts back to normal. Sulfur is particularly quick to cause olfactory fatigue. So people can be tricked into thinking the air no longer smells bad, but really nothing changed thier noses just got fatigued. This is a dangerous thing and why no matter if a space smells OK or not, the air should be monitored by air monitoring equipment for proper safety.
I think most anyone who's visited Yellowstone national park has experienced the phenomenon.
more commonly known as nose-blindness
Oooooooooh, okokok so the shape and size of sulphur bind more effectively to chemical receptors, like those found in the smelly bits (I'm a chemist not a biologist...) Which means they stay saturated for longer, and your body can only reset the receptors at a pretty static rate, also most strong smelly chemicals are just high sulphurous compounds anyways.
Ps. I read this about 6 years ago, but anthropologists think this is an adaptation not a result of chemical or mechanical factors to aid early human ancestors in scavenging dead animals.
I wonder how this works with long term exposure. I smoke pretty often and have since found that I can barely smell it at all anymore
So much death, and yet not a single fly nor a single sound. I can’t imagine how horrifyingly apocalyptic such a scene must’ve been. It’s like everything in the area just got simultaneously raptured and dropped dead. It’s the type of event we would have called biblical if it happened and was written down before modern science. Next level scary shit.
It's still Biblical.
@@abhishekconstantinewinches9907 If you mean that in a way where people made stuff up, sometimes to describe actual events to a vague degree, then yes.
This is one of those things that is just so mindblowing if you don't know the science people 1000's of years ago would have rightfully said that is was the act of a furious god if a lake just exploded and left a cloud of death behind
It would of been awesome
@@hattielankford4775 just because there’s a chemical reaction for it doesn’t mean it can’t be an act of God or biblical.
Co2 being released from pressure is cold. Those blisters are frost bite.
Genius, I doubt anyone would have thought of that
Maybe the water kept the co2 warm?
That's a good point
@@Surrenitie No, what he's saying is the change in state is endothermic - it absorbs energy in the form of heat - so it doesn't matter what temperature it starts at. If you've ever ran a can of compressed air, you've experienced this drop in temperature.
@@BlackBanditXX Yes, i know how it works, i was referring to despite that the higher up-none bonded water may have kept the co2 warm to an extent during this process. Anywho its just a theory
As a cameroonian, I can confirm this is so true. People don't live around that area anymore. We say "lake nyos has belch" just so we insert some fun in this horrific situation. By the way, your pronunciation of lake nyos isn't correct but that's not an issue.
I was more worried about “Mount Nyriagongo”. 😄
sorry this is off topic but I am planning a trip to Yoaunde and Douala, as a westerner should I have any safety concerns?
Should I advice a friend living around lake kivu to consider relocating?
@@Edmond8634 those two areas are relatively safe as compared to the North West and South West regions, where there is still war. You can go to Yaounde and Douala. However, I am sure that your embassy will give you more info as to which places you shouldn't venture into and it will match my answer.
@@joescott going back to lake nyos. one of the anecdotes use as a prevention against this toxic gas was drinking palm oil and rubbing it. I am skeptical if this saved some people, but this method is so popular a song has been made out of it. You might want to take a look at that. does palm oil prevent this suffocation? personally, i doubt it but it is worth looking into it.
One of my uncles was home brewing beer in a multi-gallon "beer bomb"; a spherical plastic container with a pressure release valve. He striped down the bomb and cleaned it, reassembled it, put his brewing mixture in, and left it. A week or so later, he discovered that he had reassembled the pressure valve back to front; when he came home to find an exploded beer bomb and a bedroom drenched in beer.
Loved this, I wish there was version where he explained it to insurance company and they paid him.
Lmao, never brew beer in a sealing container. Loose lid only.
"April F-" *BOOM!!*
@Prof. Weed Isn't it possible to get a good tasting wild yeast? Something never before tasted?
Bet he read the instructions every time after that, p-u
I remember seeing a documentary about the Lake Monoun tragedy many years ago. The marks on the bodies were found to be compression sores. It is believed the people lay unconscious for some time before they eventually died, this allowed time for the sores to develop on the motionless bodies. These were the findings at the time, so new evidence may have arisen since then .
this subject is super serious but i cant stop laughing at the under pressure bassline why is it so comedic to me
I was so confused when I though it was Ice Ice Baby.
@@AdamSeiler well you’re not wrong it is the same beat
@@depression666 I keep remembering that interview where Vanilla Ice was like "there's an extra TISH so it's a different beat!"
That’s the literal point of comedy
The baseline playing reverse for the dynamic equilibrium reaction is too awesome.
I first saw the Cameroon stories a few years back when James Cameron did a documentary on the biblical plagues of Egypt. The Nile ran red with "blood" (iron deposits), resulting low oxygen levels in the water caused fish to die, frogs left the water, and... all the first born Egyptian males died. It was thought that the heavy clouds of gas released form the Nile drifted into the low lying areas of the city. First born males were the heirs to the family assets and got to sleep in a special place in the home... the basements.
So if the angel of death was a greenhouse gas, the blood on the lintels was a red herring. Got any scientific reinterpretations of the parting of the Red Sea?
@@Pencil0fDoom Immanuel Velikovsky has interesting theories.
@@Pencil0fDoom Could just be a work of fiction. It is the bible after all.
Coolest place in the house- and the deepest. They also got the first serving of the contaminated food. Doixides or sulfides- not a good day.
@@Pencil0fDoom Technically, the evaporation of CO2 from the Nile could've caused a red mist/fog to accompany it, and if their door frames were especially easy for fog to condense on, that would've caused them to drip with red-brown water, looking like blood had been sprayed on it.
Fun fact: Nyiragongo is probably the only volcano in the world that looks like people usually imagine volcanoes: a hollow mountain with a lava lake in the middle.
Never thought about that but you are dead on.
there are about 5 others that fit the bill, but yes lava lakes are quite rare
@@flyingeagle3898 Thank you for your point. Nyiragongo is certainly the most famous of them all. In general, its surroundings are fascinating and terrifying at the same time. Relatively dangerous neighborhood, both wild and inhabited.
Such a poster child, lol. But neat little fact.
@@lonestarr1490 I'm afraid I don't understand the first part of your post. I am not an English-speaking person (I am from Poland), so I guess I lack context. Can you explain?
"Still a better love story than Twilight" One of the countless reasons why I really love you and your content. Thank you, Joe.
This is a pretty common saying around the internet
And that he photoshopped Nicholas Cage makes it even better.

I am Cameroonian and this still brings chills even now. I have tried to explain it to several people I know, but there is still skepticism among people here about what happened. The name is lake “Niyos”
Should I advice a friend living around lake kivu to consider relocating?
@@ababycow if appropriate measures have been taken, then there is no need to panic. However living close to a lake that is deep and large is risky as it’s never known when the pressure will fall.
I remember seeing the news reports when lake Nyos exploded, it was shocking to see so much death. I've since thought of it, on and off, as the lake that farts very deadly. I'm glad to see that measures have been taken to lessen its impact in the future.
The rampant corruption in business and government might make it much worse. There's a PBS doc about that, a Nova I think.
what year was this happening?
That face you make at 3:14 after whispering "That's the sound of water crying" will haunt me until the end of days. Thank you Joe. Just thank you.
That feeling when you live near a "sea" with this exact problem that, if releases carbon, can chocke half Europe.
wha
If you mean the Adriatic, with the sheer size of an event that could upturn that volume of water, it would be the least of your worries.
02:54 OK, playing Under Pressure backward was art.
I found out through personal clumsiness that diet versions of sodas are actually not sticky. This makes cleanup so MUCH easier.
That’s probably because there isn’t sugar in the diet versions
Makes sense now explain works and aluminum
Most of the stick is the corn syrup.
This was both a surprising yet super not surprising fact to learn.
Diet soda is the dumbest thing. Drink water.
Gosh I love watching your videos. I'm at the edge of my seat in the beginning of the video and every time I think "oh wow what a big tragedy" then you pull out the "It happened again but bigger" I'm blown away every time
Joe can I just say how much I appreciate your Channel... I love all your videos, but this time I was on the verge of a panic attack because of stuff I don't really want to get into right now... your dry humor made me laugh and actually feel better.
Thank you
Back when I was young, I had this basement where I was conducting all sorts of experiments with lights, a non disclosed type of vegetation, soiltypes and whatnot. I was manipulating climates and atmospheric conditions such as dramatically raising the amount of N and CO2 through the use of various canisters and/or chemical reactions that may or may not have involved burning methane in order to simultaneously balance the temperature ideal for set vegetatation. I know all about the low hanging mist and its lethality. For it to actually reach such high concentrations and effectively push the O2 up above 1 meter and a half above the ground in open air, you'd need three things.
1. An absolute shit ton of CO2
2. Complete lack of wind, no rain but pretty high humidity
3. A valley that is basically a bowl
It is quite clear that such conditions could only be met in tropical climates and very specific geographic conditions. hence, very rare events. Except then maybe for those who are experimental basementdwellers and/or like to spent their time in poorly airated subterrainian constructions like septic tanks, rainwatertanks, abandoned coalmines and postapocalyptic subwaysystems. You might just happen to stumble upon a methane or CO2-bubble.
Ah yes. Non disclosed vegetation. My favorite. How your aunt Mary Jane BTW?
@@mariawhite7337 she died a few years ago unfortunately. She was a wise woman who learned me many valuable life lessons
@@Roguescienceguy I also miss her and think of her often
CO2 pockets are one of the things they warn people about in an effort to keep them from exploring old gold mine shafts in Colorado.
@@butchs.4239 CO2 isn't the only nasty gas that can find it's way through cracks in rocks and make unventilated caverns hazardous to ones health either. Not really the sort of spaces you want to be blundering into without a decent air quality monitor at a minimum and knowing how to use it properly.
I have that table. The 4 foot Lifetime table. Got it at Costco. Don't remember what I paid for it. But it's nice that I can throw it into the back seat of my Jetta and pile the rest of my dungeon master stuff on top of it when I'm headed out to play Dungeons & Dragons. It's a nice buy, and I definitely recommend it over the six foot model that folds in the center.

I've had a can of soda explode on me before. It wasn't shook up or anything as far as I know, just opened it and the entire contents of the can instantly emptied out in a split second. It didn't hurt me or anything, but it scared the hell out of me.
Reminds me of soda roulette, where you randomly chose a unopened carbonated drink, shake the shit out of it then place it back with its unshook brethren, walk away & wait.
A coworker of mine once opened a bottle of pop and had raised it to his mouth before it spontaneously exploded all over him.
Just one thing .. Sigurð is certainly not the most Icelandic name. It is VERY uncommon here. (so Sigurðson is equally uncommon) .. it is much more common in Scandinavia
Of course there must be a girl called Ragna commenting on what is not the most Icelandic name. Greetings from Latvia. I speak fluent Norwegian, some Swedish and understand Danish - but when you guys start babbling in your version of viking-speak (sorry) - that's a whole different universe. Beautiful language, though - as is your country.
I'm guessing it's the presence of the letter Đ that makes it stereotypical, not the father being Sigurd.
Complete, ridiculous tangent - my Minnesota Lutheran church choir was singing an Icelandic hymn to celebrate the 1000th year of Christianity in Iceland (.....yeah) and our native Icelander said we had kind of a Swedish accent to our Icelandic. I figured that was better than an American accent, at least.
"...inside where it's not so hot and . . . sticky." Dude. I could hear the deadbolt on that patio door slamming into place from here. Thanks for the throwback dance beat, too. You always make me giggle, even if you DO go on to scare the pants off me by recounting one more way this planet is out to get us.

I was bad at high school chemistry. I studied hard and spent extra time trying to understand the subject. The teacher just gave me a passing grade even though I faild so I didnt have to repeat the course. Mr. Chang said to me "You need to avoid taking chemistry in college." Thanks for the advice.
I had exactly the same experience. I hate chemistry.
The math killed me in chemistry. I never learned how to use a slide rule. Yes, I’m that old.
This song got Under Pressure stuck in my head, and I forgot The Magicians version makes me cry every time. Thanks Joe Scott, now I started my day crying!

That was great, and reminded my the tear-jerking nature of the "Power of Love" cover from the TV series Misfits (the video on TH-cam is NSFW as it contains audio from a parallel scene from the episode).

Thanks for videos like this, Joe. We appreciate your work

Yo Joe, this is an eye-opening video. Super cool science we experience every day and a fantastic exercise in acknowledging the scale of the world around us. I wish I had this video to watch in high school for that very reason. Super great stuff, thank you much!
I spent some time in Cameroon in an area close to those two lakes (especially close to Monoun) and I vaguely remember them talking about a lake that exploded! Neat to see a video about it.
Good to see limnetic eruptions getting attention. Lake Nyos has always fascinated me.
For me it's just a reminder that climate change will cause a lot of issues, maybe not limnetic eruptions, but still other issues we didn't expect.
“So bad for you” Has another sip. I’m there with you Joe. The hot dogs I’m grilling are terrible too.

My son asked me what would be the most optimum amount of gravity for a planet to have to enable a human to run the fastest possible speed.
I told my son that we would have to ask Joe Scott.
... or maybe the Manleyest of all Scotts ;-)
It would depend on HOW FAR the run was. Higher gravity would give you better traction and leverage for acceleration from a start. But under 1G, fatigue tends to be an ever increasing factor as the length of the run increases, thus the faster runs would occur in lower acceleration environments. Also, you would encounter diminishing beyond a certain point with both high G sprints and low G marathons. You can't run if you can't stand up, and you can't run if your feet don't stay close enough to the ground.
The gravity is not the issue it's Air density. A cyclist uses 90% of energy just to get the air out of the way. So optimum would be slightly lower G, but only slightly as lower G, lower grip and subject to the (Moon Bunny hop). Increased O2 breather as that's your fuel. More O2 humans get like a car a turbo boost (too much you die) and in a vacuum tube. And for preference down a slope. Man In UK ran down hill faster than Usain bolt and he was no sprinter. This is why you are unlikely to see this at the olympics
Pretty cool question. I think the most important aspect is the effect of "G" on atmospheric pressure because it can, both increase/decrease resistance and therefore acceleration, and also affect the runner's oxygenation. So my bet is, as low a "G" as air pressure can keep you conscious, but more than running, it would be like pool bottom skimming at super speed.
@@ac1dflare937 one time my grandma ran downhill on her face, faster than Usain Bolt ran the world record track sprint on his feet.
I heard of a local Dam 'Rolling Over' and causing a fish kill a month ago. Was described as the bottom water coming to the top and the top going to the bottom. It was after a cold snap in winter with winds. Perhaps the top layer got cold and more dense so it went down. In a volcanic region the bottom layer could get warmer and less dense so move up.
turnover, and perhaps also sulfide
Interesting vid Joe! I love seeing how much your channel has grown.
I love the start. XD I was like "oh my god he's gonna get soaked JUST ONE JOE JUST ONE!" Love the use of "under pressure" and I LOVE that you are covering this!!! The locals actually have a mythical beast that was inspired by this. I forget the name of it though.

Well this hits home and this whole mentos geyser was my fifth grade science fair project when I was in Jersey City. I got different brands of sodas both diet and regular and determined which one went up the highest. Whichever two people had the best projects in the whole fifth grade determined by the principal and vice principal would represent the school at the city’s science fair.
I actually made it to the round of being judged by the principal, I was one of two selected for my home room, as everyone else in my class was just comparing toilet paper.
Please don't leave us hanging - which brand went up the highest???

Do a video about methane trapped in lakes and people lighting them. Also permafrost melting exposing fossils.
Wild coincidence: I learned about this disaster earlier today when I read about it in an article about R&D into sequestering liquid carbon in sandstone under the Gulf of Mexico… and how you need to make sure it doesn’t leak and belch itself up because it could smother 1700 people at once.
They found lakes of methane at the bottom of the Gulf. Methane is in a liquid state down there because of the pressure.

I love that the Mythbusters is a cited source for Soda Geysers. They proved that which additive in diet soda makes it better than regular soda.
Here i was thinking 1700 people died from dumping mentos into diet cokes?...
This is why I subscribed to this channel, your content is absolutely fascinating, thank you.
Hey Joe, I just found your channel and I've really been enjoying it. "Knowledge Is Good" said Dean Wermer's desk plaque ad I subscribe to this idea. So thanks for all the hard work and also for the great comic relief.
I've heard of the Nyos incident as the deadliest lake in history!
A proper length video at last! Bit concerned about the 'chemistry' though. It appears to show water and oxygen combining (to form a new molecule?), but the CO2 just disolves into the water - there is no chemical reaction. The sudden release of energy is not a chemical reaction, but a purely physical one - very rapid un-disolving because of sudden release of pressure.
WOW! awesome pyroclastic flow when your eruption column collapsed😂😂
"This is ourselves.....under pressure"
Oh my god, and I thought Las palma with 1trillion cubic tones of earth that could slight into the Atlantic ocean at any moment or in 100 years was terrifying... Which it is.
Absolutely brilliantly presented, this is my first video I have seen a video from your channel, so ive just subscribed and get my daughter to watch them, she is really really in to Chemistry, whilst my other daughter really loves physics. great job, loved this ❤👍.
Existential dread is fun, ain't it
LaPalma may well slide into the sea. But the inevitable tsunami will not be a fraction of what the pop scientists claim. The hill is simply not big enough.
It would be very cool to see Joe doing some small experiments that he's interested in and we too, could make in our house.

Incredibly interesting and informative and so well presented and explained.

That never gets old. And thanks for telling us about exploding lakes!
If I recall, the one lake over-turn in Africa was caused by a slide on the narrow end which displaced enough deep water to trigger the release.
I thought this video would be about a Coke and Mentos experiment gone horribly wrong.

Thanks, that was fun to watch and a lot less messy for me.
What a great video, Joe. You actually made me laugh hard. Yes, with loud noise and all. Thanks.
Nice video. really enjoyed it. for those who wonder how deep the lakes where.
Lake Monoun 99 meters. Lake Nyos average 94 meters max 208 meters. Lake Kivu average 240 meters max 480 meters.
and those lakes are high in elevation witch i think plays big role as well 1000+ meters.
13:10 That's a very weird counter. The seconds are divided in 35 units which count up while the seconds count down. 😕
Such a badass opening the can of soda at the end
This was a fun topic, didnt know this issue existed in our lakes today. Great job make it and interesting fun topic. Keep up the good work Joe!
Could they install artificial fountains in Lake Kivu, and put turbines in them to generate electricity? If so, would the release of CO2 from venting a lake be worse than from a fossil fuel power plant?
May be hard to install them without explotions
Oh wow. I've seen those fountains in videos of American (Canadian?) lakes and wondered why they had them. Makes sense now.
Lake Nyos had a CO2 vent installed in 1990.
Not actually too hard to do.
Lake Kivu’s methane content means rather than a suffocating cloud, that will be closer to a fusion bomb scale fuel air explosion… (3160 Mt yield (or 120 times the yield of the Tsar Bomba)).
If full conversion occurred that would break windows in Europe and Africa wouldn’t have a population in central Africa any more.
Perhaps after scaling up the methane extraction to the point that they effectively run out of methane in the lake. Then having previously made the fountain assemblies with new or or repurposed turbines from the methane-steam generators, implement them at a rate deemed unlikely to trigger a mass CO2 release. The power grid would still need power and the lake would have a second reserve of potential to tap into. They don't even need to burn all the methane first, just extract and bottle it for later use or export it. You then have to worry about the GHG impact, if the amount of CO2 is sequestered in the lake is comparable to a significant fraction of global annual emissions. Compressing and liquefying it would take about as much or more energy than is gotten out of its extraction, so that is a non-starter. Perhaps channelling it into greenhouses locally, or as far away as pipelines of low pressure gas can accommodate. I've heard of concentrated atmospheric CO2 being used to multiply greenhouse yields. The most problematic issue being the health and safety of the workers, but that is solved by using low level breathing masks that provide canned breathable air in a constant stream over one's mouth and nose, with excess and waste being vented off to the side. Locally, outside the greenhouses, there could still be an asphyxiation hazard, but that is remedied by an exclusion zone (within which all personnel must wear the aforementioned breathing apparatus) to a radius where any excess CO2 that escapes the greenhouses suitably dissipates. There being two jurisdictions on that lake actually is a benefit as both can do this in concert or individually if the other is incapable or won't.
It was a landslide that set off lake Nyos. A large chunk of one part of the shore that was unfortunately placed on a steep slope allowing it to overtiurn the lake when it broke free.
I guess that would have sent a large underwater tidal-wave through the sediment, lifting the carbonated water high enough that the pressure dropped sufficiently for the release - I expect that this somehow fed back on itself somehow releasing a large amount of the CO2 that was in solution - nasty - maybe it was just like a cloud of mentos sweeping along the floor of a very large tank of coke... yikes !
I truly enjoy watching your videos. Very informative with just the right amount of humor. I recently went back and watched your video about your predictions of COVID-19. Pretty accurate if you ask me. If you have not already done one, you should do a new video about COVID-19 and your predictions. Would be very interesting to hear your point of view of your own predictions. Otherwise, just keep rolling out the videos. ✌
Thanks so much for the VID!
Do you know what I love so much about your channel? You're the only person that can make me afraid of living next to a lake. I wanna thank you for ruining my dream of owning a house by a lakeside.😭 You've educated me on so many things that I'm pretty much paranoid about EVERYTHING. Love your channel 😁😁 I'll be in a corner curled up in a fetal position looking forward to your next episode.
I was way too much happy and giggling at the first "pressure". Still smiling. Pure joy, thanks.
These are my favorite videos, a little science and an interesting story. Thanks Joe.
I completely enjoyed this video. Thank You
Ok Joe, you have reached the height of your talent. You can just walk into frame with a table in your hand and make people laugh. You go boy!
I have no idea why but your attempt of the Mentos in Coke seems to be the most honest version ever, You have completely eradicated my lingering desire to try this myself. Great video, thanks, Joe.
Hey Joe, I love your videos! I have been subscribed for about 2 years now. I used this video in my physics class to show how experimentation can be dangerous and safety precautions should be observed. 😆I am an American teaching physics and math at an international high school in Shanghai, China. YOU ARE AWESOME! Your channel is awesome! Keep up the hard work. I learn a lot from your channel.😀
That sample of "Pressure" was one of the best things this guy has done
I found out at work that dropping those Gatorade flavor tablets into carbonated water will also cause an eruption. The small amount of water that remains in the bottle does taste pretty good though.
