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.

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.

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 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.

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.

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.

[@LoneStarr1979]

... or maybe the Manleyest of all Scotts ;-)

[@digitalnomad9985]

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.

[@ac1dflare937]

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

[@elkikex]

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.

[@kerryarrant1523]

Always, I learn something new often so very strange, which is really how I view your channel. You rock, thank you very much.

[@RockinRoland72]

I love your videos Joe! I really appreciate your talent and I love learning new facts. Love your sense of humour as well. I feel like you may have missed a golden opportunity in this video to include toots and the Maytals pressure drop.

[@keithcacahuete8066]

Incredibly interesting and informative and so well presented and explained.

[@darenstroud6254]

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. ✌

[@herblee4180]

Really enjoyed this. Excellent mix of enterainment and education. "Gee Mr. Science"

[@jacksonburger2081]

Gotta be honest, I really liked your intro. Doing science project type things that relate to the topic but aren't direct is awesome. Reminds me of Vsause's intros and I love it!!

[@samuelrodriguezrivera6856]

Completely unknown to me till now. Thanks for the vid!!

What a comforting video my daughter and her family are currently living in Rwanda on Lake Kivu. They had to evacuate for the volcano last year.

[@PiaMalmberg86]

As a person who is studying to become a science high-school teacher, this is such a great video :D Thank you for doing this and keep it up :) Love your videos Joe :)

[@downunderveggiegardendiaries]

Heard that if you put Mento’s in Coke as a teenager it does something interesting. I thought it would be a taste thing. I put 3 in a big bottle of coke and screwed the lid back on and it blew the lid off like a rocket and hit the shed ceiling way above us and rained down coke all over us at My Friends Birthday Party setup lol. Luckily it was in the shed with a dirt floor.

WOW! awesome pyroclastic flow when your eruption column collapsed😂😂 "This is ourselves.....under pressure"

[@tomasvensbergas826]

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.

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.

[@michaelquigley1411]

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.

[@nickitoff9629]

Joe delivers a great message with science and humor. Thank you for doing your experiment, it was awesome!

[@paulhaynes8045]

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.

[@BHuang92]

I've heard of the Nyos incident as the deadliest lake in history!

[@crisymakesnoise]

Did the coke and mentos experiment for the preschoolers i taught and the most iconic reaction I got out of them was "WOOOW!!! MILK COMES OUT?!?!" I was in tears😂

[@mavric1177]

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!

[@alfredotorres4516]

you should make a video about the Paricutín volcano, it is the youngest volcano in the world There are photos of how it grew and testimonies of people who saw how the floor opened and hot air came out. It's very interesting you should check it out.

[@electricwheelchair]

13:10 That's a very weird counter. The seconds are divided in 35 units which count up while the seconds count down. 😕

[@donnavorce8856]

Great Scott! Wonderful lecture and good teaching of science and some foibles thereof. 11:20 scary and terrible to imagine TWO MILLION CORPSES . . . PLUS PETS, FARM CRITTERS, WILDLIFE. Incredible.

[@GlitterPoolParty]

Thanks, that was fun to watch and a lot less messy for me.

[@andydbedford]

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 ❤👍.

[@Shinzon23]

Existential dread is fun, ain't it

[@davidelliott5843]

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.

[@chevtruck1000]

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.

[@julesgosnell9791]

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 !

[@rnistuk]

That never gets old. And thanks for telling us about exploding lakes!

[@austencourpet]

These are my favorite videos, a little science and an interesting story. Thanks Joe.

[@kobeathris4552]

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?

[@aaronhpa]

May be hard to install them without explotions

[@nikiTricoteuse]

Oh wow. I've seen those fountains in videos of American (Canadian?) lakes and wondered why they had them. Makes sense now.

[@allangibson8494]

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.

[@ckl9390]

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 would be very cool to see Joe doing some small experiments that he's interested in and we too, could make in our house.

[@RomanDavidDeSilva]

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.

[@segacat1]

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.😀

[@nikiTricoteuse]

That was great. Loved learning about the lakes. I'm in my 60s but have never done the coke/mentos thing nor had l seen it. It's pretty cool. Summer's just around the corner here in Aotearoa/ New Zealand so l'm definitely gonna try it when hosing myself down won't give me hypothermia.
