There’s actually a much easier way: 1) Block off your pool to the outside so you can only access it from your house 2) Don’t let anyone in your house 3) Don’t pee in your pool If you follow all these steps, you will know exactly how much pee is in your pool.
Well what about the people that lived there before unless you just got the pool there while you where there or you where the first person to live there
When I was on a cruise some years ago, I sat by the pool bar having drinks. After several hours it dawned on me that nobody in the pool ever got out even though they were having drinks nonstop...
Mark, could you revisit this considering the nitrogen content in proteins such as hair and skin that could form trichloramine that would give the smell too?
@Dries Jansen i feel like it could be a little bit naive to say that no trichloramine at all would form, since in many pools the water still runs through the filter until it is changed
hair and skin won't really break down in the pool water (it gets filtered out eventually), so the chlorine would not have acces to the nitrogen so no trichloramine forms from hair and skin.
If that was the basis they were using for their results, sure. But they weren't. The Trichloramine was just a "funfact" not what they were using to determine their numbers. The numbers came strictly from the artificial sweeteners they found.
5:50 that’s cool ! That means no one pied in my families pool when I was a kid. We added everything needed, but it never smelled like public pool, I always wondered why. Now I have the answer 😁
I wish you would have also consulted a certified pool cleaner as well. The reason your results were skewed was because you pulled from the top layer of water. In order to properly test a pool you need to get samples from 18" deep. The water may not have been changed recently but they could have filled it or it could have rained. In order to get rid of that smell is... wait for it... more chlorine. Would love to see this again with say Scott Ford there would be so much more useful information about pools too. Anyway love your work.
Could that "pool smell" also be caused by sweat? The reason they couldn't test the amount of urine is because sweat has the same chemical makeup. Wouldn't that lead to the same conclusion that sweat also reacts in the same way with the chlorine as urine?
Nitrogen trichloride, also known as trichloramine, is the chemical compound with the formula NCl₃. This yellow, oily, pungent-smelling and explosive liquid is most commonly encountered as a byproduct of chemical reactions between ammonia-derivatives and chlorine. Yes it is from sweat and urine reacting with chlorine
Ofcourse he knows all the stuff. I am still in engineering school and I know all of that. Mark has completed engineering and he was in fricking nasa. Ofcourse he knows about that stuff.
Proud to say I have always avoided peeing in pools and don’t recall ever doing so. Did I ever think I’d be watching a video about it? Never. Also why did I watch this when my local waterpark is about to open up for the season
@Sevro not everyone has perfect grammar. Not everyone comes from an English speaking country. So can you excuse a minor grammatical error just one time. I’m certain if you were to kindly tell them “hey, just a friendly reminder that it’s ‘they’re’ not ‘their’”, they would’ve probably edited the comment to be grammatically correct. No offense by the way.
I used to swim competitively and always thought when we went to a pool that smelled extra strong of chlorine, it must be super clean. 😂🤦♂️😢 I'm now ruined for swimming.
Okay, so if sweat has uria in it, does that mean all it takes for chlorine to smell like a swimming pool is for someone to sweat while in it, and no one has to actually pee in the pool? (I’ve also heard that when you’re in water, specifically warm or hot water, you sweat no matter what, which is why you’re thirsty after a shower, so it seems pretty unavoidable)
I was a pool operator for a few years and I was under the impression that the “pool smell” was caused by both dichloramines (chlorine reacting with sweat) and trichloramines (chlorine reacting with urine). But I don’t know if that’s any better for nostalgia’s sake
2:07 I love how Mark Rober is listening to all that genius nerd stuff and just says “of course” while innocently nodding his head to everything she says lol
I can almost smell that pool smell just thinking about it... and now what I know what it is, I don't think I'm ever going in a public pool again.. Also, as a hot tub owner, the best way to keep people from peeing in it ... don't let people in it.
Me after watching: Am I the ONLY one who never pee in the pool. Like, why??? Why would anyone do that? You are practically swimming in your own pee seconds after you finish doing that......
This also makes the FRENCH word for "Swimming Pool" make perfect sense ... Piscine ... pronounced 'Piss in' ... one of the very few french words I remember from High School French class 35 years ago.
"we all wondered how much per is in the pool" I'ma be honest mark. not once in my life did I ever care to know and if I did I never wanted to know lol. But this is fascinating
Mark: asthma is more likely to occur in elite swimmers Me, who knows how to swim, is a part of my swim team, and had asthma since birth: I’m four medical universes ahead of you
would have been interesting to test a lake or the ocean as well. Yes, comparing it to the total volume would be difficult and the results would be less than accurate, but even a generalization would be pretty cool to see.
LOL. I used to tell that to people all the time. If you own a pool company where your state requires you to get a pool operators license like here in Florida you will need to take commercial pool operator courses where they teach you how to test and clean pool water as well as check calcium hardness and PH. One misconception people have is that when you smell that really intense chlorine-type smell from a pool they automatically think there is too much chlorine in the pool when in fact its the exact opposite. When a pool is clean you can barely smell the water if at all. But when there isn’t enough chlorine you smell what we call “Combined Chlorine” which is when the chlorine molecules combine with the dirt and contaminates in the water and create a decay. Thats what your basically smelling. So steer clear of pools with an intense chlorine smell.
It would be interesting to conduct a blinded experiment where at least ten participants would smell the two buckets and tell which of them would contain urine? Participants not involved in the experiment are not allowed to stay close (listen, etc). I believe that if the urine/chlorine density would be respected in normal conditions, it would really not be easy to infer the same result presented by you. For these reasons, you may need to increase the number of participants as well :)
Thanks for taking the time to figure out this USEFUL info 🙏🏼😅💛 Also, your friend's pool is really nicely designed - lovin the plants along the back length 🌿❤️
Y'all not even prepared for how excited I got when he walked through the doors of the Stollery and announced Lindsay at the University of Alberta. I go to the University of Alberta! And our university has done some really cool stuff so it made me really happy to see him working with the university
But what if the pool has a filter system? I mean the pools i go to have drains for excess water that overflows ( due to the displacement of water when someone swims ). The drains are placed throughout the perimeter of the pool. and there is always new water being introduced ( from the a fountain or like tap ish thing at the bottom ), doesn't this make a pool that filters the water to be cleaner? If assuming, the water that is drained is properly treated and then pumped back in.
Does the same rules apply in a SALT WATER POOL? Is there a way to just filter the urine? Does an ultra violate light filter remove the pee? Thanks in advance. Cheers.
I’m interested in seeing them do a test on a control pool, one that was just filled before anyone got to swim in it, and then compare the artificial sweeteners in that to a used pool. My guess is that some of those artificial sweeteners could also be already in the water (depending on the source) that they used to fill the swimming pool.
@Lori McKee They seem to take the average sweetener present in urine based on presumably a large sample. It likely doesn’t give the most accurate reading but it gives them a general idea about how much urine is there.
I think he mentioned that. What I don’t remember is why artificial sweeteners? Doesn’t the amount of artificial sweetener found in urine vary widely from person to person or even from neighborhood to neighborhood?
I used to think: The stronger the chlorine smells, the cleaner the pool is cause there's more chlorine in the mixture... I'll try my best to forget about this vid when I swim in the future, thanks.
Same !!! Lol I'd always be like "mmm I love the smell of a pool! It smells sooo clean!!" Lmfao I'm sooo grossed out. Esp at the YMCA you walk in the door and you get hit with that "pool smell" isntantly!!!! So gross. I'm so grossed out!!!!!!
Now chlorine dioxide (CLO2) smells immediately like that distinctive pool smell without pee. We use it to clean with. It is a gas. It can be stabilized for a few hours in water. Anyways this has that same smell. Maybe some pools use this along side chlorine like the water departments use during boil orders to clean with. Just saying maybe not all is from pee in pools
I always had a suspicion that the "pool smell" had a little bit of piss in it, just a little bit. Must've been the humidity of indoor pools that made me think so.
Thanks to you now I'm gonna bring my portable inflatable pool with me to the pool and, once again, thanks science for ruining but also improving my life. and also thanks to you Mark, you are suck a nice person, everyone should be like you!
I actually wanted to ask that does Urea jn sweat have a significant impact in the observations. Because I read that Sweat has about 1% or urea only when compared to Urine (Idk if it's authentic or not)- so I was wondering if such miniscule quantity will have any major impact on the Observations. Again i am not sk sure about the figures!! Really enjoyed the vdo tho.
Samples should perhaps be gathered from different parts of the pool, and from different depths, to see if the concentration of artificial sweeteners is more or less equal.
This science may help me understand why I had urinary pain. I always suspected it might be the Coke Zeros and diet drinks. Since stopping artificial sweetener, I haven’t had a problem.
MY brain just thought back to every swim class and hotel pool I've been to that smelled so strongly of clorine. Now it makes sense, every pool with a higher ratio of kids smelled so much stronger...

Yeah ik
I never thought about it that way oh no swallowpool water almost every time I go to a pool

When I was on a cruise some years ago, I sat by the pool bar having drinks.
After several hours it dawned on me that nobody in the pool ever got out even though they were having drinks nonstop...
oh hellna
@Brit Lew Hey I went to a pool that had a bar serving drinks in the middle of the pool once at a resort in Cuba.
@Breakfast Television i was at the Pool Bar, not in the Pool 😁
Did you get out at all ?
🤢
Mark, could you revisit this considering the nitrogen content in proteins such as hair and skin that could form trichloramine that would give the smell too?
@Dries Jansen i feel like it could be a little bit naive to say that no trichloramine at all would form, since in many pools the water still runs through the filter until it is changed
but the sweat for example does dissolve in the chlorine so that will also be part of the smell
hair and skin won't really break down in the pool water (it gets filtered out eventually), so the chlorine would not have acces to the nitrogen so no trichloramine forms from hair and skin.
If that was the basis they were using for their results, sure. But they weren't. The Trichloramine was just a "funfact" not what they were using to determine their numbers.
The numbers came strictly from the artificial sweeteners they found.
You know she’s a genius when she’s teaching MARK ROBER things lol
comment number 101
mark is more in like machines and stuff he isn’t exactly qualified in every category of science

XD
Love seeing mark taken back by his discoveries 😂
jokes on them I go to random pools and pour in packets of artificial sweetener
I once forgot 100 packets of sweetener in my pocket
@Maojie Yan oof
Lol
Some men just want to watch the world burn…
I wonder how they feel about that
Can you imagine how awkward it was for him to walk around the airport with about 6 bottles of different types of pool water 😂
I just like yourpicthcer
ever thought about he might have put them in his checked bags?
Luggage bags
Lol
haha
Lol who knew the smell of pool that nostalgia is actually a pee nostalgia 😵
Wellcome to the club
Noooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
@David Hsu He was just telling the truth. Don’t be rude
I’m a swimmer, and now in kinda disgusted
😂
5:50 that’s cool ! That means no one pied in my families pool when I was a kid. We added everything needed, but it never smelled like public pool, I always wondered why. Now I have the answer 😁
phew you aren’t a psychopath
🙄
This is one of those "ignorance is bliss" moments
At least now we can start stopping with peeing in the pool
Yup
@CursedJade Have you never swam before? Sometimes water goes in your mouth and you accidentally swallow it.
@LeSkip Bayless why would you drink pool water
Uhhhh Im going to wipe this from my brain, and go pe in a pool
Thank you, never was a fan of pools or swimming, now this has cleared up any of my doubts of whether I should go into the water ever again.
But what if it’s your pool😨
Bro go Huawei
But swimming is cool.
Ikr, people are gross
The fact that the pool smell is caused from pee is never going to leave my mind
@Zachary Abner same lol
Y e s
I regret reading the comments before I watched the video

I wish you would have also consulted a certified pool cleaner as well. The reason your results were skewed was because you pulled from the top layer of water.

In order to get rid of that smell is... wait for it... more chlorine. Would love to see this again with say Scott Ford there would be so much more useful information about pools too.

I used to go to a pool and the water was constantly being filtered in and out, Idk if that is the case for all pools.

@Antoine Dns C CD. B b. B b
Admire the commitment from Mark here. A lot of peeing he had to do to fill 13 gallons for demonstration.
Do you know the meaning of irony? Lol
it was yellow dye

@Sevro oof
Theoretically I could compare samples of before and after my sibling gets in the pool to see if they peed
Smarted speech ever
Yeah.. iguess

This has made me never want to swim in a pool ever again, thanks mark!
Thank you so so so much Mark for these kinds of ideas where we get to learn so much, which is really beneficial : )
This had me crackin up cause I been going to the pool more often than ever this summer. 😆
I used to swim competitively and always thought when we went to a pool that smelled extra strong of chlorine, it must be super clean. 😂🤦♂️😢 I'm now ruined for swimming.
@Antichrist Imagine if they put the thing that makes the water blue if u pee in an olympic pool xD
Could be sweat...
But still
Hey ima competitive swimmer to. Swimmer to swimmer tho- I always thought the same thing
ME TOO!!
@Anna boii how do u swim in your bathtub, must be a large bathtub

(I’ve also heard that when you’re in water, specifically warm or hot water, you sweat no matter what, which is why you’re thirsty after a shower, so it seems pretty unavoidable)
I was always thinking: "why is my swimming pool not smelling like one?" well I am happy about the results lol
Mark always makes science easier and fun for me ,Like usually I get bored of science
i never had the chance to swim in a swimming pool. and thanks to this video , i totally do not regret it
Him: Explaining science

what if someone spills coca cola zero in a pool?
@sour cream that’s what I hope it is

I was a pool operator for a few years and I was under the impression that the “pool smell” was caused by both dichloramines (chlorine reacting with sweat) and trichloramines (chlorine reacting with urine). But I don’t know if that’s any better for nostalgia’s sake
Wow, so you can confirm the pool doesn’t smell like chlorine until it’s been introduced to bodily fluids?
2:07 I love how Mark Rober is listening to all that genius nerd stuff and just says “of course” while innocently nodding his head to everything she says lol
bcuz hes a nerd smh

Also, as a hot tub owner, the best way to keep people from peeing in it ... don't let people in it.
No matter how many times you watch the same video that mark has made, it's interesting ever time
You mean terrifying
Interested to know how a salt water pool would affect this vs. chlorine.
Note to Self: If pool smells like chlorine - enjoy swimming in pee water.
@Daddy Dog same

just take a shower after 🤷🏽♂️

kak lol

i think this is what he means by lol
people are arguing about pissing in pools
This also makes the FRENCH word for "Swimming Pool" make perfect sense ... Piscine ... pronounced 'Piss in' ... one of the very few french words I remember from High School French class 35 years ago.
@MrBigRig okay that wasnt bad i'll give you that
As a French guy myself I can confirm this.
In Spanish it’s “piscina,” because people love to piscina pool.
Je confirme 😂
True, but that came from latin, piscis (fishes) > piscina

Long story short, If you have swam in a pool, you basically just swam in strangers' pee, water, and chemicals.
@Yes XD
Yeah I totally needed that info
I have never peed in any pool. I just think it's weird how warm it is and how soothing it is..
Thanks Mark! I now don't wanna go swim in any pool ever again.
This guy is teaching things that are on our minds
Growing up, our friends had a pool. They had a sign: “We don’t swim in your toilet, don’t pee in our pool”.

Question: How much deep underwater you have to go before you can't pee even if you want to?
There surely were an investigation after this video in the family owning this pool, to determine who was guilty 😆
After watching this, more people are regretting drinking from the pool than peeing in the pool.
Who drinks from a pool?
@This is Supposed to be Anonymous it means that people won’t try to stop if everyone else does it
That is an experiment on its own. It shows people only care about themselves.
Does it matter where you get the water from? Top or bottom of the pool? Does that make a difference?
I used to think:
The stronger the chlorine smells, the cleaner the pool is cause there's more chlorine in the mixture...
