Yay for the new objectives! We'll be using 1000x clips often from now on! Hope you'll enjoy it!
Jam's Germs I love your work! Extra kudos on those paramecium at the end, they were lovely with their crystals. Thank you so very much for sharing your work
Hooray!
So I guess you could say you... achieved your objectives?
Very, very cool! While we are at it, aren't you also interested in 4k recordings? :) Or at least 1440p? It could make these videos that much more crisp and beautiful!
Dude, those shots were amazing! Keep at it!
"We carry our rivers inside of us" sounds like a post-rock song or band.
Mind if I use it
““We Carry Rivers Inside Of Us” plays with some interesting ideas but it’s ultimately too indebted to Sigur Ros’s first three albums to be truly interesting to fans of the genre.” - Pitchfork
It goes well with Africa soundtrack
🎶we carry our rivers, inside of us🎶
"You treat me like I was your ocean
You swim in my blood when it's warm
My cycles of circular motion
Protect you and keep you from harm"
-Steve Miller Band, _Jungle Love_
Analogies and metaphors are awesome! I don’t know those songs you mentioned. Sounds a bit funky.
i visited a waste water treatment plant in a geology class once. we walked up to one of those massive round tanks that was empty and there was water making a tiny pond in the very bottom with ducks hanging out by it. i was watching the ducks and thankfully noticed that one was a little black kitten! i went into rescue mode, told my instructor and the class and we flagged down some employees, i was terrified they wouldn't rescue him because they couldn't get down there right away and my class had to leave, but i'd given them my number and vowed to drive all the way back there after they got the kitten out and they did. he had fallen aaaaaall the way down into the thing but amazingly had no injuries. he was soggy and sad and covered in duck weed from the little pond, that's what we ended up naming him, Duckweed. i fostered him for a week and he went to a super good home.
very cool, hope Duckweed is alright.
What this comment related to this video ?
@@hellatze yes.
@@hellatze uh, did you watch the video? maybe you have a hard time making connections... i'll explain for you: the common theme between the video and my comment is waste water treatment.

A tardigrade pooping in our poop water; the circle of life
Incepooption.
Never thought I’d see tardigrade poop in my life
They're so cute when they poop...OK circle of life...I love.
*The water you're drinking now, that's me... That's my activated sludge, human. You're welcome.*
yes. rotifer is my favorite water flavor.
Thank you.
Thank you cousin.
"Activated sludge".
Excuse me *what*
I thought you made this account for this vid but clearly not
One of my favorite field trips as a kid was to the sewage water treatment plant. To see how all these organisms take disgusting water and transform it back into potable water? It’s amazing!
Yes, I’m a dork. But 10-year-old me couldn’t get over the algae and snails that lived in the biowheels of the plant. 😁
ayarel01, that was my least favorite field trip! The brown aeration tanks smelled so bad that I was ripping up weeds, hoping they would have enough scent to drown out the essence of turd. They didn’t.
I went on my first wastewater treatment plant field trip when I was 22. I went with my microbiology class, fittingly. The smell was tolerable even at the "stage one" of sorting through literal crap. The snails were also my favorite. And best part was, it was only 10 minutes away from my campus and around 15 minutes away from my home city. I technically grew up in proximity to such nerd-dom, and I'd never heard of the place until adulthood. Even though chances were, children aren't as enthused by poop processing as they are by the mere word "poop."
@@unknowndeoxys00 lol you said poop.
More than half of it is actual bacteria.
@Amilah If being amazed and interested in life is being a nerd then I'm a happy and proud nerd.
@Amilah Yea, balance is everything. "Nerds" have the reputation to be asocial.
I’m a water and wastewater treatment engineer and you guys did a great job summarizing how primary treatment works! At any treatment plant in addition to this you’ll find other processes using fermentation, phosphorus absorbing bacteria, and sequences of reactors cultivating aerobic, anoxic, and anaerobic bacteria in precise arrangements to produce clean water.
Wow, I knew that we had to remove phosphorus to prevent algae blooms and other issues an excess of it can cause (where I live the lake is often unsafe due to farm fertilizer runoff anyways, since that escapes the treatment system), but I guess it never occurred to me that we used bacteria for that step too! Makes sense though, instead of having to buy and add some chemical to precipitate the phosphorus out or whatever, the bacteria can just be renewably farmed in the reactor for that step of purification, right? It also never ceases to amaze me how the chemistry of life, tuned over evolutionary time scales, is so much more effective in cleaning, processing, and even energy production and extraction than anything our artificial chemistry or inorganic technology can currently achieve.
revenevan11 Inorganic phosphorus removal is far less efficient than biological removal. Under certain conditions some species will absorb large amounts of phosphorus so the phosphorus step is all about encouraging those conditions then settling out the heavier bacteria.
Phoslock is a good thing for phosphate and phosphorous absorption. Lanthanum binds to the phosphate and doesn’t dissociate. I believe its very expensive though.
God I love this channel so much. Everything. The music, the narration, the writing, the beautiful visuals. It's equally educational and entertaining. It's freaking perfect. There is nothing to improve here, only the joy that comes from every episode. Please don't stop.
Yes the music is notably very good.
Completely agree!
ME TOO !!!
@rrobertt13 Me, the narrator can be too pretentious and occasionally gets things very wrong (like the idea that humans can't see polarized light with the naked eye, said in the microscopy video)
Honestly, this is my favourite video from the Microcosmos so far. A delicious balance of education and pretty pictures!
Pictures of poop e_e I think imma puke
Ahh, HSMR... So relaxing. Hank is the perfect narrator. The only person that can make wastwater and sewage sound chill.
Microbes are so important and valuable but, in this case, I'm glad they... go to waste.
how dare you
that pun is allowed on this channel.
Our bodies are made of similar creatures... So called "CELLS" only difference is that those are foreign cells.. Strange to our bodies. So we feel sort-of sick when we see those different organisms. A survival instinct: Disgust.
Ironically we "waste" them out to control the population of microorganisms 😂
"Gah.. this water's horrible... add some more germs, wouldjya?"
Ooh! Hello new message!
I love you new message, I check you all day everyday.
@@tylerscudder9358 You're not the guy who goes through my trash, and keeps leaving nose prints on my windows, are ya?
@@NewMessage That would be me, sir.
@@fantoast6932 ok WHAT
If it exists within our planets magnetosphere just assume it has microbes .
Heck, at one point bacteria were found on the outside of the International Space Station, those little buggers unbelievably float up that high
@@SmoochyRoo do you know how big our magnetosphere is?
And for all we know, Voyagers I and II could carry some thus putting the bacteria'S area of influence bigger than the Sun's magnetosphere :D
There's a place in Africa where scientists have been completely unable to find any life
Even the molten core?
I think 10-20km depth is the limit where they found very-slow-growing bacteria.
So remarkable how Hank keeps fighting with his worst enemy at every episode: slow speech
Ah, just last month I spent 2 weeks photographing a full water and sewer system for a large city nearby... how neat to now see the microorganism side
Huh, what's your job called? Do you enjoy it? (if you don't mind me asking). I'd imagine that some parts of the sewage system would be gross, but at the same time, especially with stormwater portions, traveling around the city to photograph all the parts of the system seems pretty chill and like a bit of an adventure. The sewage bits would probably get old quick though lol.
revenevan11 no worries! 😁 i’m a commercial construction and industrial photographer, so I do a lot of hydroelectric plants, dams, and things
Iike that. The timing of my most recent job and this vid just ended up being really neat to me! Spent the time seeing it physically, and now I can get a microbial idea too. I love it and wouldn’t trade it for anything!
The smell can get really bad on certain days, but i got lucky and it wasn’t too bad, got to see everything from the reservoirs, water filtration, wastewater, hydrant flushing, repairs, water mains, etc. it was fascinating and neat.
Im a wastewater treatment plant operator by day and a photographer by night and have an extensive industrial background. How does one become this?! I would love to bring my two worlds together!
Point of order: flocculate floats; precipitate sinks.
For everyone watching this video on their phones while on the toilet: Thank you for doing your part!
I'm a wastewater operator of several activated sludge facilities. Your eloquent narration of our bug farming makes me proud. Thank you for this beautiful explanation of the micro-life we take for granted.
I love how everything in life ultimately comes down to food.
My 6 year old was fascinated when I told him what the bacteria were eating.
Thankfully.
Cariss Stewart pooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooop
@@Pyro-et9vs Half of it is bacteria.
Pretty sure a 6 year old would listen to anything that's shit related. Why do you think Katy Perry is still popular.
@@yoursexualizedgrandparents6929 ouch. true tho
This channel fills me with joy, and ambivalence.
Like when I wash my hands, and realize the existential implications of some cosmic force doing the same.... like "eh, there's germs on my dimension;"
On the bright side, if there's anything else this channel is taught me, is that those "hands" wouldn't stay clean for long. Life is one heck of an economist, it finds a way. Never ceases to be incredible.
I remember learning about the wastewater cycle in middles school, leading up to a class trip to a wastewater plant. The first step is big vats where microorganisms break down solids and anything else they can. The vats rare constantly roiling and give off humidity because they are highly aerated and heated slightly to maintain the best environment possible. A few steps later are towers where anaerobic organisms reside as water filters down through them.
I've seen three comments about people taking a middle school field trip to their local wastewater treatment plant, and I'm so jealous lol. I guess my school district just never had that field trip, or I missed it because I switched schools going into middle school, but I would've loved that! Did the first steps giving off all that humidity smell at all? I'd imagine that the water as it first arrives to the plant would smell unbearably bad!
It didn’t that bad, but I think it was giving a lot of CO2 or something since I got dizzy when we were on the catwalks over them. What smell there was wasn’t like raw sewage, it smelled like some kind of chemicals, idk how to describe it specifically. The two effects kind compounded each other though, so I was glad to move on to the next part.
@@revenevan11 I'm super late but generally you can contact your local wastewater plant for a tour. On the topic of smell, it really depends on the exact process being used, but generally in activated sludge systems the smell isn't too bad, just kind of musty.
Really fantastic episode, I can't believe how much I have learned since you launched this channel. It's even more amazing to discover just how much we still don't know about these tiny beings with whom we are so intimately connected.
I'm so grateful we haven't yet invented a way to smell recordings
I was just talking about how grateful I am for modern waste water treatment! This adds a whole new dimension to my gratitude! 🥰😍 thank you for your awesome videos Hank and James!
This video is a good example of how amazing and full of wonder the most mundane things can be.

Tardigrade Pooping II: The Return
I truly hope that clip gets used in at least a dozen more videos. It is art.
@@Tinyvalkyrie410 ikr
"Electric boogaloo" goes better still :P
Just saw microscopic poop from a tardigrade.
Definitely the coolest thing I've seen on the internet all day
1000x eh? Someone got a new microscope!
Useless fact:
Activated sludge is "Belebtschlamm" in German, meaning roughly as much as "living mud"...^^
*furiously thinks of a way to use that*
That's the sound I'd imagine living mud would make
It's also the name of a rap song by Del tha Funkee Homosapien
@@SCWood " _Belebtschlamm,_ I choose you!
Use _Grammar Nazi!_ "
Loving all the micro world videos. Thank you to everybody involved in making them.
"What can i say except..."
"...You're welcome!"
Those extreme closeups were amazing! Thanks again for a fascinating video!
I started working in a wastewater treatment plant 2 months ago, and I was wishing for this video for the last two months, I thought it would be great if there was a great Journey to the Microcosmos explaining how bacteria has a fundamental role in clearing our wastewater!
I hope there will be another video with awesome music about Protozoa and Metazoa in wastewater treatmemt 😍 that would be a great video
I learned something I didn't know: how water treatment works! Thanks!
Terrific close-up on the workings in the microcosm
Thanks, microorganisms!! Thankroorganisms.
"The drama of the food chain" is why I watch this stuff!
New favorite channel! Not one to comment, but the editing in this one was particularly mesmerizing. This could definately spark some latent passions. Also probably the most beautiful footage of poop sludge ever. Well Done!
Thank you! My goal was to make poop sludge watchable and I'm happy to hear I have done it!
The quality of this channel; I'm absolutely stunned. I truly love your content - please, keep it up!
*ah yes another episode of Hank Green asmr*
i love this! i enjoy you connecting the microcosmos to our reality
Great video! Please continue doing things like this!!!
Great episode! I wrote a study to see the effects of human waste fertilizers on farmland and waterways, hoping to start it this coming year. This channel sure inspires thought!
I love this so much, thank you for this, it sparked an idea for my architecture final year project.
this series is gold
Wow, amazing video as always and so enlightening. Best biology channel on UA-cam, keep it up! 😁
Time for some relaxation to Hank's super smooth voice.
Thanks, Journey to the Microcosmos, for putting me off breakfast.
I can't even imagine what would happen if you somehow fell in that tank :O
😨 pray that it would be a quick death.
saxoman1 It'd be really gross and you'd definitely get sick but you'd probably be fine.
That guy from jackass did it :\ gross
It'd be horrific, but since those bacteria probably hadn't met a whole living human in many many generations most of them would probably be harmless
Thanks, this is a kind of narrative explanation in the form of a dramatic novel with amazing images of the microscopic cosmos that is sewage! Excellent indeed! 👌
This really makes sense and helped me a lot as an environmental engineering student. Keep it up!!❤️
I've always been fascinated by microscopic creatures. As soon as I see a new episode, I close any other video and click on it 🤩
Everything about this channel and presentation is fantastic. Thank you so much for the inspirational and interesting content, such a pleasure to watch!
great vid, i could literally watch an hour long documentary of this stuff.
Just threw on "lofi hip hop radio - beats to relax/study to" in the background while watching this... and I will never go back. I am soooo relaxed... :-)
4:44 this made me think while in toilet that... Imagine... So many living things are pooping rn at the same time with u 😂
Thank you for subtitles
studying how microbes affect our macro life is very interesting.
😊👍 keep up the great work!!!
This was fascinating. I have to find out more about this process and these facilities.
Oh yeah, and bioreactors in general are fascinating as well. If you're not familiar with the channel "The Thought Emporium" then I'd highly recommend looking them up to learn more about bioreactors (and many other things). There's a video on one of his projects where he DIY genetically engineered some bacteria to make a luminescent (or maybe fluorescent?) protein, and then grew them in a bioreactor he made from an old lantern!
@@revenevan11 I am not familiar with that channel. I'll look it up, thanks!
I worked for many years with a group of people who provided such a banquet, an EPA Awarded wastewater plant. If you ever get the chance to take a tour, do it.
4:36 me right now on the toilet
Thank you.
Have you guys ever considered constructing a course for assessing water health, from your basic home garden pond to wetlands? You do this so well, you should consider it both a gift and a skill.
I just love everything about this
The only problem I have with these videos is that I can't concentrate on Hank's voice as it's so goddamn relaxing my mind drifts away from listening. Plus the mesmerizing visuals don't help at all. It's like a private mind massage and I'm in love with it, keep it up!
Why do you feel the need to b l a s p h e m e God's name? Please be considerate to people of faith.
I can see the abundance of vocabularies in the microcosmos.
That was really, really fascinating! 👍
Very different than normal, but amazing! I appreciate this insight into microbes affect on our Urban lives. Very cool!
i got a cell culture video ad and i love it
Fascinating...
Oh man, those ending paramecia are gorgeous!
Love this channel ❤️
Waste water treatment is evaluated by the EPA by measuring the Biological oxygen demand (BOD) of the water that is returned to the environment. You take clean water, add a certain amount of food media, then measure the oxygen level. Then you add a small amount of the treatment water, incubate it for 2-3 days and retest the oxygen level. Back calculate any dilutions and each treatment facility is required to keep their values within a certain range based on where they are dumping the waste. Unfortunately they do not have great methods for punishing facilities that fail, they typically get a slap on the wrist or a small fine.
Your videos are so soothing lol
Wonderful as alwyas
Excellent!!
Video is interesting and beautiful as always but I also expected an explanation of how do they clean toxines and chemicals, such things that are supposed to be harmful even to them
Another excellent episode
In the UK, septic tanks are being replaced by mini sewage treatment plants that use this microorganism 'treatment' to turn domestic waste into water clean enough to drink.
Great channel, this videos are super interesting
4:37 tardigrade poop is the cutest
Coprofilic: This is yummy to me
Normal water consumer: This will be yummy to me
Waterbear bacontracks are not two words I had ever thought to put together before
The miracle of sludge!
That final shot with the paramecia is just... wow. So beautiful, that's some award-worthy shit right there
Maybe I should get into this field. I hear from reddit that a lot of sewage people are terribly corrupt and negligent. These bugs remind me of my favorite video game called Reassembly where you build space ships out of blocks and they fly around on their own.
I've just discored you channel, it's incredible!!. It would be very useful if you can also include information about the the microscopes and techniques used. thanks!
This video compelled me to get a glass of ice water.
Through my research, I often give presentations about wastewater treatment. When I get to the aeration tanks (as shown at 5:24), I always let my audience know that this is where the shit hits the fan.
LOVE THIS CHANNEL
I love this channel so much :)
I grew up just outside Kalamazoo, Michigan. In the early 60s the progressive city government opted to replace the aging and overloaded sewage treatment system with THE FIRST BIOLOGICAL SEWAGE TREATMENT PLANT is n the United States. They built it and to make sure it really worked. They added neighborhoods to the new plant slowly. Make sure this is working before adding a larger load...
And. It DID work. Perfectly.
Until the southern edge of town was added in. This section was industrial and included Upjohn pharmaceuticals which made antibiotics.
The living system was dead in two weeks.
The city concluded that it didn't work and scrapped it.
That sucks! Such a good idea and so much potential and taxpayer money wasted! Something really needs to be done about all the pharmaceuticals in our waste (and unfortunately even drinking) water.
When David Attenborough eventually passes on (may it be many years from now), can the BBC please get Hank to narrate all their nature documentaries.
Could you do a similar video like this for aquariums? (ammonium, nitrites, nitrates,....) "beneficial bacteria", algae, cyanobacteria,...
I love how the narrator speaks in a dramatic, theatrical, sometimes uncomfortable way. Fun.
When are you guys going to do an episode on fungal networks?
❤ your videos!
