- Water is one of the most abundant and important substances on Earth, so you think we'd know everything there is to know about it. Turns out, water is so much stranger and more complex than we ever thought! Join Olivia Gordon for a new episode of SciShow and find out why water leaves scientists with more questions than answers.
SciShow has a spinoff podcast! It's called SciShow Tangents. Check it out at www.scishowtangents.org

Water expands when it freezes. That's weird enough for me.
Everything weird about the universe is caused by hydrogen bonds.
If you don't move around, you'll get bigger too.
@@TheRogueWolf that.... sort of makes sense.
@Every Buddy yeahh, timothy dalton
If you are a fish in a cold climate it is essential for life.
So when Bruce Lee said to "Be like water" he was telling us to "stay weird, fam." Wow, that's heartwarming.
Bruce Lee would never say "fam".
I love this 😁❤
@@SteveFrenchWoodNStuff Calm down Steve. I'm sure there was slang when you were a kid, stop being an old fogey.
@@SteveFrenchWoodNStuff ok boomer
More like stay adaptable, learn to improvise and surprise the hell out of those who thought they had you all figured out.
"As water is heated, its heat capacity barely changes until, all of a sudden, it crystallizes and becomes a solid."
This statement broke my brain. I thought that water turned to steam when it was heated. What did I miss? I've rewatched, and I still can't figure out what this means. Was part of the explanation left out? Do you mean at extremely low temperatures and high pressures? Can someone kindly explain this to me?
Usha Alexander they’re talking about water that’s been supercooled well past the normal freezing point and then the temperature gradually raised.
@@WhiteVioletButterfly , thanks for the explanation! I thought there had to be some explanation like that. But it wasn't clear to me, when watching the video. Let me first say, I love Olivia Gordon in these Sci-Show videos, but somehow, this one kind'a lost me.
@@ushalexa If you re watch they give the temperature range as -120 (something) to -53.
Pay attention to what was said right after. They mention at which temperatures it occurs at.
@@DuckTapeWarrior1 Very interesting , your article,and I can read in french!!! .I've printed it. But, yes, the nice host had only few minutes to explain! Thank you!
My favourite tidbit on liquid water is how the ions of water (H3O+, H2O, and HO-) coexist and are stabilized by their neighbours, even in neutral solutions. It explains a lot about its innate catalytic activity in almost every chemical reaction that occurs in the presence of water.
What in the goddamn hell are you talking about?
i think they’re saying water is both a reasonable base and acid at neutral pH. why you gotta hate on someone appreciating science
@@benjamins7225 A catalyst helps stabilize intermediate products in chemical reactions, such as platinum in the reaction between oxygen and carbon monoxide. Water has a very similar role in stabilizing intermediates, though it's rarely referred to as a catalyst because of its ubiquity.
@@ozonefreak2 not necessarily hate, more like overwhelmed by all the scientific language.
@@RBuckminsterFullerI understand this, but water is stabilization of the intermediate is not the only role of the catalyst, it would additionally have to reduce the activation energy of the reaction. Platinum and Water cannot both be considered catalyst, what you described, the stabilization, is the very property that makes water a good solvent. I apologize I'm the previous comment had the wrong tone
Personally, I think it's weird enough when I spill a few ounces of water it can wet the table or counter, run down. get everything in it's path wet, then still puddle on the floor.
I find it weird that yanks use an outdated unit of weight to measure volumes.
@@FoxDren I find it weird that people watch videos made in the USA, then complain that they're using their own measures. If I watch something from the BBC, or Europe, I cope with metrics.
@@christelheadington1136 it's a science video therefore SI units should be used. The world should not have to struggle through such archaic units because some moronic yank refuses to change with the times.
Ascdren I find it weird that you think anybody asked.
Ascdren OK SMOL BRAINS. A UNIT IS A UNIT, METRIC IS NO BETTER THAN ANY OTHER, IT IS LIKE LANGUAGES. UNITS ARE COMPLETELY SUBJECTIVE AND ONLY EXIST TO STANDARDIZE QUANTITIES OF PROPERTIES. YOUR BASE 10 SYSTEM THAT IS METRIC IS INFERIOR TO BASE 12. WHAT IS EVEN BETTER IS TO REDEFINE ALL THE UNITS SO THAT THE CONSTANTS = 1 OR USING CONSTANTS TO CREATE UNITS LIKE THE PLANCK UNITS.
What a coincidence. I too very slowly relax into a liquid state every weekend. And I’ve been told my eyes get glassy.
Me too. I think it's because I'm mostly water.
@ThePark 627 hes actually a tool
I'm a scientist in this field. There are many misconceptions in your video, like what "no man's land" refers to, quantum effects in deuteration and the problem of amorphous ice. I would suggest reading textbooks on water and ice before exploring those state of the art papers. Petrenko's Physics of Ice is an excellent book.
As a chemical engineer I can confirm we don’t “sometimes” tend to treat water as a neutral background for chemistry. We do it ALL the time 😂.
There are two things that are very impressive...
- carbon's ability to make soooo many compounds
- water making such a great environment for all kinds of reactions, compounds, ions...
No life without these wonders.
3:55 the lateral knee X-Ray is upside down
Don't be that guy.
Hilarious.
It was an elbow
@@ohtheblah Hey now...don't tell a "fib;" eg. fib/tib and be sure to "Pa-tella" guy the truth.
I was confused as to why the knee looked so odd but didn't dwell on it. That explains it.
The weird thing is our body knows how to take advantage of those properties of water while our brain can't understand it
It's like the Thermos, which keeps hot drinks hot and cold drinks cold.
But how does it know?!!
@@montycantsin8861
🤣🤣🤣🤣🤣
@@montycantsin8861 good one
Well the body doesn't really know anything. It's just something that has evolved and encoded in our genes through trial and error.
@@montycantsin8861 Well a thermos is actually 2 containers, which has a vacuum between the 2, which prevent thermal transfer.
Or maybe it's a /whoosh for me, yeah I think it is
Glass? Veritasium convinced us that glass is solid.. this episode is weird..
For human time scales, it is. It's so slow we can't observe it in an 80ish year period. So for our timespan, it functionally is a solid.
It is a solid for all intents and purposes it is slow slowly flowing it would take thousands of years to move at all.
What? No! Google it. The glass flowing thing is a myth. The glass phase is a thing but glass itself does not flow however slowly any more than steel does. Its a solid (edit: not crystal) not a fluid.
Benjamin Barney
Glass isn’t a crystal - that’s quartz
Glass is a type of amorphous silicon dioxide
@@benruniko I was under the impression glass is an Amorphous solid, clumps of molecules without a crystal structure locked together. Your point is valid though, it is a solid.
Me: Hey chemistry looks cool, let's start with something fundamental and easy, like water.
Water: Imma bout to end this man's whole career.
I read a science book that quoted the definitive book on liquids where, in the preface, it said that water was so complex there wasn't enough room in the entire book to discuss it.
You also left out the fact that water is the only substance where its solid form floats in its liquid form. Also if it didn't there would be no life on Earth as bodies of water would freeze from the bottom up into a solid block that could not melt.
Water is heated until it crystallizes and becomes a solid? What am i missing here?
Yeah something got backwards there. Right after that, super-low temperatures of -123 and -53 deg. C are shown. Something went awry in the editing of the content, apparently.
I think that's the whole point why it's weird.
Crystalized water when heated? That's new...
I think they should have prefaced that part by mentioning that they were starting at subzero temperatures as low as -123°C.
Yeah that really bothered me so I did some reading, and it turns out what actually happens in water is the opposite -- a glass is formed by removing heat, not adding it. Sounds like a pretty big piece of information to leave out there...
I’m thirsty
Which kind?
FireWall both
What about it having the uncommon trait of expanding when it becomes a solid
If I'm not mistaken, isn't that what causes it to be one if the few, if not the only, solid to that float in its liquid form.
Plot twist: Water is normal and we are just weird
we are water o_o
Surely, I'm weird but I'm mostly water so...
1:17 That's a funny way of saying "scientists haven't been able to observe this phenomena yet."
I thought it was disproved that glass itself behaved like a liquid over long periods of time. Why is it still called a glass phase?
That is indeed a myth. That being said, glass is a very special and weird substance. So weird in fact they thought up a whole different category to describe it, an Amorphous solid.
But yeah no, glass windows dont get thicker at the bottom over time.
@@mistrants2745 thank you!
Because even scientists get tricked by "common knowledge" myths
Scott Bradley
I like to see people making things with glass rods.
Weird water fact: I actually willingly paid for Dasani once at a theme park. Speaking of things Science has difficulty explaining.
Better than paying for deer park.
I think that counts as being under duress
@@Kissarai very good point
Loving that water geometry!
Man, another one SciShow pulled off, what a brilliant question, water! Two things I want to say, as a person who never leaves a comment. First, when are you guy going to do a Collab with In a nutshell? You're the cool kids in the place! And second, to my knowledge that's the first time I see you quoting only C° degree only, as a non US it's good to have an ISO ref, even if translating in Anglo-Saxon measure to compare. We're watching from all around the world! Keep up the good work, love you guys :)
This is one of the most baffling surprising and interesting scishow episodes ever!
Fantastic stuff.
"The odds are pretty good you've already encountered a bunch of it today"
She knows I'm watching this while sitting in the bathtub 😶
"All water everywhere knows where all the other water is."
what?
@@lonestarr1490 If you remove all barriers, one portion of water, such as a lake, will know where another portion of water, like the ocean, is, and actively move towards it as if it was pulled by an invisible force. :)
The only science program that list their sources in the description 💘 . That's why you all are the best!
Yay!! I have been waiting for this episode forever!! Thank you! :D
Wasn’t the “glass is actually a slow flowing liquid” idea disproven?
Clearly the terminology hasn't been updated.
Where was it disproven?
Not sure what you mean. It is more accurate to call it an amorphous solid with a glass-liquid transition. However, it would also be correct to say that these states share properties with liquids.
@@roseneathorganics2597 nothing and you are wrong
@@roseneathorganics2597 Part of my career as a mechanical engineer was industrial glass forming. You made a correct observation (thicker at bottom) but a wrong conclusion (it flowed). That 80-year-old glass was not uniformly thick to begin with. The person who built that window put the thickest end on the bottom.
It's crazy how as water freezes its density actually lessons which is pretty weird
@Ricky Barber yes I am aware of that it's just a weird trait for liquid to freeze like that and have that trait to expand aswell that when it is frozen and becomes ice the ice is a near frictionless surface
Awesome video. Love you, Olivia!
I kinda wish they'd devote an entire episode to glassy water. I'd love to learn more about this "glass phase" in general; I didn't really even know about it before.
Man, how are we still running this game on such a bugged physics engine?!
We need to hire better developers.
In Alaska at -45 I can hear my breath freeze when I breathe out
Tree Ring your breath wouldn’t freeze lol
@@camkind6952 Something's got to happen to the water in your breath. Those temperatures are how you get laboratory dry air, with only tens of ppm of water in it, not, say, a percent.
Jim Baker your breath wont freeze, the tiny droplets of water that come along with it will
Tree Ring has, not is
I love the irony that scientists strive to avoid yet constantly faceplant; whenever they think they've got some concept of the universe entirely defined, they always find some unexplainable exception that throws it out.
Nice to have a non sponsored video from time to time!
Olaf: Water has memory!
Homeopath in the audience starts shouting “I’ve been saying that all along! You people didn’t believe me!”
Well kinda. Its not like human memory, you cant test it on historical dates and stuff.
1:22 timely means opportune, or happening on time. You meant time-consuming.
Zachary Weiss yes, her misuse threw me off.
lovely stuff
Beautiful information 🥰👍🌊💧
" Our love is like water, penned down and abused for being strange"
Olaf said "water has memory"
So water is going to remember you saying it's weird!
“Water will remember you said that.”
Homeopathy
@@evunotry-force2073 But only with the magic tippy tappy bit at the end. The only time memory is improved with a thump😂
If I were water I would be flattered.
Wow, very good reporting!
Your presentation skills are getting better and better! :)
Sci Show: *hits blunt* Water is weird, bro..
Weird water fact:
It has no taste but it is pure pleasure when you're thirsty
Mr R to the B water does have taste, but the taste is so bland and normal you barely notice the flavor
Water is great!
Water's taste is it's temperature
Water is not as sweet as heavy water.
XtreeM FaiL Who in their right minds would want to drink heavy water as opposed to good old regular water? Commercial grade pure heavy deuterium oxide is EXPENSIVE.
You could find regular fresh drinkable water everywhere for free.
The effect of a charged substance on the nearby water molecules is a huge deal in understanding some of the subtler aspects of how electrodes work, too. The rearrangement of the water extends much farther than we used to think, and can actually shield electrodes from each other.
You're welcome! I love what you guys do!!!!!!!
00:07 Sponsored by Lynn Shackelford, is that Rusty Shackleford's long lost sibling?
jbcdu87 yes
Smh we even fat shaming water now, it just has a couple extra neutrons damn
I watched a lecture about water years ago that talked about a crystalline structure for water that reacted to IR light.
Great vid! You should do a follow up and explain the science behind how high caliber bullets shatter when fired into water and smaller bullets like a 9mm go right through
I also have a glass phase during which I slowly relax.
Hahaha that's what she said.
Chelsea Older Perhaps it’s a generational thing, I think we’re interpreting happy hour rather differently. I've yet to encounter someone with a fetish for glassware, but then my experience, admittedly, falls short of comprehensive.
"something about water's heat capacity is weird"
I mean, it's like, the highest by volume, isn't it?
Cracked Emerald Yeah, I mean, I used ice water as a treatment for brain freeze from ice cream when I was a kid, which seems somewhat ironic to me. (I would still use ice water as a brain freeze treatment, but I’m halfway to 22 years old from 21 and haven’t had brain freeze in ages for some reason).
Joshua Hunt probably due to relegation and regulation in consumption. Also anything lower temp than the ice cream can cure brain freeze. Such as putting your tongue to the roof of your mouth will warm the blood vessels enough to flow again.
@@joshuahunt3032 never had "brain freeze". Whatever that is.
@@sethmp333 I have heard of it but never experienced it. I can drink a glass of ice water and not feel anything in my head. It sounds weird that you would feel something there.
@@sethmp333 I have done that plenty of times with no effect on my head lol. I love ice cream and eat it often. It just sounds weird and like something I would have noticed.
"there's a pretty good chance that you've seen a lot of [water] already"
You say as I'm drinking my ramen noodles.
loving water and Olivia💕✨
In the energy of The Great Brad Leone: "WOURDER."
This video is interesting but....
Sci show: Your bones are wet ant sticky
. . .
Wow!! All about water and more than I ever thought would be weird!
Can we take a moment and appreciate the versatility of water
Bruce Lee: Be like water.
Weird people: We already are.
Water: "Pay attention to me senpai!"
So didn't know where else to ask this but SciShow Team, have a question for you. I was sitting underneath my deck during a storm and there were water droplets falling through the cracks onto the concrete below. The drops that fell onto a thin film of water seemed to occasionally splatter geometrically... Similar to a snowflake in pattern almost. Looks like it was usually 10 main splatter paths creating almost a decagon shaped splatter pattern. So my question is this. If a perfectly round droplet falls onto a still body of still water, does it splatter in a predictable pattern?
Otherwise thank you for all the awesome content your team puts out! It is definitely one of the greatest shows ever to come out of youtube!😎
I think that there is really something profound about water as I spend many happy hours sitting on a certain rock by a beautiful flowing river. I feel it is the transmitter of ‘consciousness’ around the universe too.
scientist : "with our technology, we will achieve immortality, colonize the space then eventually rule the universe !! "
also scientist : "what is water?"
Forky asks a question: What is water?
God: I need a substance that will provide life to the earth
Physicists: wtf is this stuff
😁😁😂😂
Love you SciShow

When you haven’t even touched water today.... and you’ve been up for hours....
But you're like, 70% water so you have because you touched yourself.
Glenn Griffon bold of you to assume he’s touched himself
@@agh9224 lol
Didn't you know? Water is touching you from the inside. Just like your skeleton!
@@agh9224 It was double entendre. Technically you're touching yourself almost constantly. rubbing your eyes, rubbing your shoulder or arm, if you're a man and you pee standing up. If you've scratched an itch or picked your nose. You've touched yourself.
Water also interacts with chemicals without participating in the reaction. It can form a protective layer around molecules, force two molecules into proximity and in case of enzymes it can play a major role in pinning regents in place and quite often its a key part of the catalytic mechanism (like becoming OH, or H3O).
Yes! Perfect! Awesome
No, you're weird! 〰️〰️〰️🌊
Water... It's deep...
I'll go back in the corner...
Yeah go back into the corner Derrel this is why we can’t have any good things derrel
I wish I understood more of this. Meanwhile water expands when it gets hot AND expands when it gets cold.
Which is weird!
* bookmarked to listen to again and again.
"You've probably encountered a lot of water today"
Me, sitting here drenched from the rain: yeah you could say that
Doesn't water-glass transition temperature depend on presence and number of potential nucleation sites?
Not much of an expert but aren't you mixing up a crystalline phase (standard phase states) ie ice with a solid water amorphous "glass" like "pseudo" phase ?
claude ghendrih Since the glass state is transitional between liquid water and crystalline ice and there's a wide temperature range the transition occurs over, I figured nucleation sites would also be related, though I'm only guessing there's a positive correlation of transition temperature with number of nucleation sites present.
@@Dan-ud8hz Ok I wasn't sure you'd understood this rather fuzzy presentation but it appears you're way above my "pay grade "
claude ghendrih bah, I'm just curious
All the TH-cam hipsters making quippy jokes to be one of the cool kids.
Doom Food yes, many jokes not especially funny if at all.
I don't know why, but this episode made me extremely happy! I'm by no means a chemist or physicist, but water is such a fascinating subject!
I get...a huge boost from water now...supplies me with tons of physical stamina and energy throughout the day.
Sometimes I wish that you realized that words mean things.
Any "weird" aspects of water likely have a correlation with life itself, clues to what we dont know about how life occurs etc. Since water is one seemingly essential requirement for life as we know it currently. ✌
This is actually a super interesting discussion, but unfortunately it's often overlooked in conversations about extraterrestrial life and the chemistry that could enable it. I'm glad others are pointing this out. Another feature of water that make it unusual amongst many common liquids is its heat capacity (it's really high). This is what allows it to moderate climate so well, which was likely essential in creating a stable environment for the evolution of life here on earth and likely elsewhere.
long time not seeing you on scishow welcome back XD
Yall had me worried I was gonna drink the wrong form of water on accident and devolve or something for a second

This right after a video about how much more we have to learn about physics
So, today I learned that "Repulsive interactions between 2 polymers" is actually the scientific name for "two girls, one cup".
Normal human: water
Starbucks normie: 2 Hydrogen mix with 1 oxygen in liquid state
also no ice
My mind, is officially blown.
Honestly this is so interesting
Esha Diva if you really think about it... it’s just a bunch of blah blah blah, like a bunch of complex words sequenced together to create a fancy storyline that conjures fancy images that spin around and around in your head, and echo back and forth like a chamber... in the end there was nothing, no conclusion, no enlightenment, no knowledge, just the stimulation of the definition of words memorized in your mind... but in the end all she offers is a big shrug 🤷♀️... a big “to be determined”... and if you really think about, that’s what every single scientific or intellectual, or philosophical concept will do, just keep you chasing the carrot, while they mind f*ck all of us with more confusion...
The last time i was this early , water was normal(apparently).
