Up next: Five chilling facts about fire
MelodiousCoast7 lmao
i wish these were 5 burning questions about fire...
or 5 questions about water that are flowing on the internet
Outside. Now
.......
?
I skipped the ad at the beginning.
Braedon Ondos puns are the best kind of jokes, tbh
There's a point during water staleness in which it turns better than normal water. This time is usually during the hours of 12-3am. This water, know as "night water" is proven to be the most refreshing beverage to exist.
My cat used to dip her paw in the water bowl and lick her paw to drink.
Jimmy McInerney my rabbit just splashes his paws in water bowls...
That's so cute
My kitty does the same!
My cat used to eat this way. He passed away last June but he taught my other cat who occasionally does this still
I had one who did that, too! She'd lick the drops off and then dip her paw in for more until she was done. It really was cute! 🐾
If you boil extra water, you can put it in bottles and freeze them for future use.
Sadly people don't do this because they think tap water is infinite
Toxic Killa But the question is will it still be boiling after I defrost it? Cuz otherwise it's not worth my time.
But then you end up with solidified dihydrogen monoxide. Dihydrogen Monoxide has been known to kill millions of people.
Jeremy Ellwood H2O =/
Jeremy Ellwood yeah it just killed a lit of people cuz of hurricane harvey
This guy looks like Stefan but can’t be bc he’s not wearing a Kurzgesagt shirt
Josh Antony Kurzgesagt, you're welcome
mapffff I WAS SO CLOSEEE
stefan who?
Hello, SciShow! Do you think you could make a video explaining the current knowledge of cerebral aneurysms? I had one rupture at 19 and after learning so much about them, I would love for a bigger audience to learn of them!
i have seen your message a lot of times here. i hope scishow makes a video about it. If they don't (because of busy schedule), i will try to make one for you as well :)
Dm or email them instead, they’ll notice it easier
5 wet facts about fire
The running water thing mostly works. As an X-ray tech I often had to employ this. There is a test that allows doctors to look for blockages, bladder masses or kidney stones. It requires the patient to drink water that contains iodine which shows up white under X-rays so you can see all the structures. Thing is the ureters (the tubes that lead from your kidneys to your bladder) and your bladder have to be completely empty for this to work. Generally we would ask patients to pee just before the exam but sometimes, either because they were only partly filled or out of worry about the exam, they wouldn't be able to. So.. we'd put them in the room and run the water and that worked most of the time.
I was going to say, my water tastes better after sitting out, because it loses that chlorine taste. Then you went and explained exactly that process. I always have a coffee mug of water that I fill in the bathroom every time it gets low, and sip on it through the night. The water is always grosser right after it comes out of the faucet, and becomes sweeter and less chemical-y after a few hours. I suppose I don't mind the extra CO2 in the water as much as I dislike the Chlorine. It may help that I don't live in a very urban area, so the water doesn't have too much CO2 to absorb.
"Drink when you're thirsty."
Thanks science.
love you guys, amazing job in every video
Watching this instead of studying for my science test oh the irony
Thats fine. Christians don't believe in science, anyway.
Freddy Looger *because that has anything to do with his comment
Rebel Goy wow I failed my science test at school and now I work at McDonald's
compilation is a good approach to gain the knowledge lost in pile of videos,keep em coming ,as always Awesome 🤘,hey hank!
I read a study recently. (wish I could find it) It's apparently not necessarily good for you to constantly have crystal clear urine. It concluded that urine would optimally have a very light tint. It also concluded that the color of urine isn't an accurate way to determine that you're dehydrated or not.
Very nice compilation!
Thank you scishow, My science teacher has an assignment where you have to do a summary of a scientific article. I did it on your video about disposing garbage into volcanos. Thank you scishow for the 100% on my science grade!
water you doing
Normally me and my girlfriend just binge watch TVs shows on Netflix (when we aren't working) but, I just found this channel and now I know what we will be doing all night and probably the next few nights. Love your videos so far guys, keep up the good work.
man you have a girlfriend? i dont even have a pet well done
Don't you mean boiling questions?
Boiling water jokes are so hot right now!
Perfection
I love these compensations! This patron demands more! (and on the patreon page!)
It would be neat to have a video correlating heat and olfaction. Michael mentioned how cold water has less flavor (through olfaction). versus warm water.
This is the seeming reason that food tastes best hot.
There is a lifehack to place stinky shoes in the freezer.
More information about temperature and olfaction would be great for everyone as well as anosmics like myself.
One thing I don't understand, is in the last video hank said "drink when you're thirsty" if I did that, I'd probably have about 32-40 ounces, which I know isn't technically enough
I've gone more than a week, more than once, without eating because I had to choose between food and bills. I chose what adults and parents always choose. I paid what I owed and lost weight. I bought my prescriptions, paid my electric bill, water bill and mortgage. It wasn't fun, but that's what it was like to be a lower middle-class American. Then I got laid off and got a job at Lowe's, where I wish I had applied twenty years ago. I've been promoted four times in two years and now make almost twice the living wage I was making when I first got hired. Lowe's pays over $11 an hour to start.
Very good! I already subscribed! I tend to operate slightly dehydrated, so I'm going to get a drink.
i watched this after a night at the bar. drank so much water while watching. this video is my
new hangover fix.
Hey people I'm a medic... when you dont drink water you do get a big old IV and some fluids and once you're feeling better. Some desk jockey from the billing department which no medic knows anything about sends you a bill with a few to many zeros for a liter of ph balanced water.
.
@2:51 "you'll feel like you're dying a little bit,...mostly because... you're dying"
LMAO
patient: doctor doctor what has happened to me!
hank: Your dying a little bit!
patient: but why?
hank: mostly because your dying.
patient: that was very helpful
They brought the whole team out for this one
Stephen I used to think you were awkward and corny. Now you're my 2nd favorite host right after Hank. I love you, keep making us laugh!
Could you use a ph gradient in a hydrogel for energy stuff?
Or like a swimming pool?
I have to drink a huge glass of water before I go to bed and when I wake up. I'm so dehydrated all the time.
Adam McGrath me too
but your pillow is all wet
Adam McGrath do ye drink the rest of the day?
Adam McGrath Try to wake up in half of your sleep and drink more and go to sleep again
The end of sleep and initial waking period are the time at which your body's water levels are at their lowest naturally. I tend to start my day with at least 2 large glasses of water +/- tea.
A corollary of this is that when we (often the cardiologists or respiratory physicians) are diuresing a patient (drying them out, usually with frusemide or the like) we need to be careful about the timing. Classically they are given early eg 8AM and 10AM - as we try to avoid having people peeing all night. However, one can often get a better diuresis by waiting a bit later - when the patient is less dry.
You should make another video about the Mayan calender and 2017!!
What's the science behind rock skipping?
Is this a greatest hits episode?
The Turgor Test is only effective if you don't already have a skin affecting condition such as Ehler's Danlos. I can drink as much water as is healthy in a day or more or less but the results are the same; my skin takes a few seconds to bounce back due to Ehler's Danlos Syndrome (which, by the way, would make for an absolutely fascinating episode). The syndrome affects my joints, heart, and collagen. This can affect the elasticity of my skin making it stretch further and take longer to properly reposition itself. Just a side note.
Again, Ehler's Danlos is a rare and mostly unknown condition that some have argued led to acrobatics and contortionists. It could make for a great episode.
Edit: To be clear, I have Ehler's Danlos as well as 2 of my 3 siblings.
I like the last advice. Just drink when you're thirsty and don't overthink it!
Wow. I have never watched your video in the morning, and I have never noticed that Hank talks so fast
Got thirsty just by watching it! haha
Water is everything!!!!
no wonder so many drinks are 'best served chilled'
Wait so you want me to have a whole gallon of waters (3.7 liters) worth and still have my pee be a light yellow? There's no way in hell my pee won't be crystal clear if I have 3.7 liters worth of water in a day.
The title is lit🔥
The first 20 seconds could easily become a top tier meme.
Watching this while drinking an ice cold glass of water!!! Ahhh!!!
Please do a episode about Turners syndrom!!!!!!
how sharp can an object get (and top 5 sharpest objects), how to fall to and stay asleep or how to enter and stay in REM sleep, why do you feel refreshed after a nap sometimes or feel worse then before you took a nap what causes the different outcome?
Yay, water totally my favourite.
I like Hank the best. I like the way he talks.
This guy is easily pleased
Watching this while drinking water

"Ah water"
*casually drinks water then proceeds to talk about the science behind it*
Such a Bill Nye type of opening
This presentator is getting better and less boring :)
After watching this, my eyes are watering with a burning feeling.
Did I beat anyone to the punch with my dry humor?
The first part with hank made me want to go get a glass of water immediately.
What about using a yeti or a covered cup? Does that affect the taste of water overnight?
Like would the air in the cup if it's covered keep the chlorine in it?
Why does night-water taste SO GOOD
Nurses have known for years about how the sound of running water makes a person feel the urge to pee. I’ve taken many a fresh post-op patient to the bathroom for the first void and turned on the sink to help them overcome their sleepy bladder. Almost always works.
I have a question
I once was running electricity through a glass of water for my robotic classes and after an hour or so it turned yellow.
Why??????
Aditya the water got scared and peed itself
so it's come to this...
a scishow clip show
2:08 I’ve been there! I wasn’t dehydrated though.
I only subscribed cause of hank green, the best person out there
I have a thought experiment I shared with some friends: if just the core of a planet somehow collapsed into its swarzschild radius would it consume the rest of the earth with it? (keep in mind black holes don't suck they have gravity, arches support themselves {would this be the case for spheres}, no more gravity would be added the mass would stay the same, and gravity would pull equally in all directions)
Can you cover celestia smoke rings?
my job is mostly outside, I have a roof over my head , I drink lots of water. also eat bananas they are cheap so I buy more than I can eat and hand them out to others, what other fruits can I eat to keep safe, I also want to limit the fatty foods I eat--- what would be a good diet for me
Tbh growing up that 'stale' water was my favorite. I would make deliberate choices to try and keep my water tasting that way when I could.
Regarding the 2nd video:
If a glass of water goes stale overnight does it become salt water? Because it is no longer fresh water.
Master Therion that joke was FLUID
Master Therion lol

Danielle Spargo (and anyone else interested)... On a serious-ish side note, I might advise that you are in pretty good surroundings if your water can be allowed to reach a warm room temperature and still taste reasonably good. (okay, some people don't care for the authentic taste of water... oddly)... But follow me on this one.
I live in a particularly rural area, and my water is spring water (natural all the way)... I'm quite familiar with the local geology, and regularly test it anyway... BUT I've been to many cities, and I always let the first glass of water from a tap sit long enough to be proper room temp'... If it still passes my nose and taste tests, I can trust it. If not... I worry and test it, or just buy the damned bottled variety... You see, it's not just the water you're tasting. It's mostly all the "other stuff" in it. Water has a taste (sorta), but at the treatment centers, they purify it, add chlorine (highly toxic) and some places still use hypochoric acid (even worse toxic)... Then they leave it in settling pools, filter it, and add "proprietary minerals" to "renaturalize" the flavor so you'll actually drink it... On top of all that jazz (and I'm over-simplifying because... comment section)... you've got miles and miles of pipes that it runs through before you even see it coming out of a tap or garden hose (most cities it's all the same water)... SO you might be really well advised to do similar things by practice. I applaud you in your current practice with the cup...btw... but now you have a fairly thought out reason (or several) as to why you should definitely continue.
And the Romans used lead to sweeten wine and water, so... yeah... :o)
30 years or so ago the water on the farm i grew up on started tasting funny, turned out a few weeks earlier a possum got into one of the 4 massive tanks up on the hill and drowned,
the tank was isolated from the others and drained and cleaned out.
so, thats a thing that happens
can you tell us a bit about the fourth phase of water?
You guys should do a video on why cracked bells don't ring.
Why can't water be compressed? I know it expands when forming a solid, but why is it's liquid form the most dense?
I think it's because of the crystalline structure that water molecules form into, which makes them less dense it
"Ring bell and I salivate, how'd you like that?" 🎶
Omg I'll literally die without water 😂😂😂
Wow Yasuo Mains really?
😂🔫
Cx
Can you make a video about why water crystelises the way it does?
1: hey, am I dead?
2: no
1: Guess I'm drinking enough water
Can water take a part of anything with it ? Like dissolving...is there anything it can't show signs of being exposed too?
That intro tho 😂
Water is the leading cause of drowning
1:45 How could this happen?
Have you SEEN how slow Naboris is?
XD I think I’m literally the only one who got that The Legend of Zelda: Breath of the Wild reference ;)
So I'm extremely dehydrated on a constant basis.. good to know.
The narrator is awesome...
Seeing the slow motion of the cat it looked like it was bending the tip of it's tongue inward like it was "lifting" the water up. Could that be how it drinks water? Just more delicately than a dog?
So like does drinking soda aka carbonated water actually satiate your thirst? And by that I mean if we drink carbonated water do we actually get water that are bodies can use?
This video made me... thirsty. Drank like 2 bottles of water.
I remember one time i was having a bad headache couldnt figure out why and then i slowly started going blind in my left eye... after drinking a good bit of water i was able to see right again and the headache went away...
This episode made me thirsty
so its come to this a scishow clip show
Seems more like a SciShow experiment featuring four hosts.
Is it possible to freeze water WELL above the freezing point
I did a paper on hydration, and ran into hyponatremia. I was an infantryman and was told to drink 1 quart every hour when it got over 90 degrees, around Sand Hill, Ft. Benning, Ga (E 2/54) , that usually happen by 8am, Our MRE's have a "Ton" of salts, and I didn't think much of it. A few years later I'm now Disabled and partake in my states Medical Cannabis Program, I heard about
a "Cannabis User" who drank so much water he caused brain damage. Can you do a Hyponatremia video?
Is it bad to drink cold water often?
In the Philippines, the elders usually attribute sickness such as cough to drinking cold water, and also accuses that cold water can destroying your appetite, cause ulcer, upset your stomach etc when you drink water after you woke up in the morning in a empty tummy and stuff.
Peeing by sound reminds me of a woman tea lady who demonstrated to my friend how men hearing the tea poured from some hight tended to leave for the urinals.
Seeing the toilet makes me have to pee or poo more as i arrive
What exactly are those coloured blurs that appear in your vision after seeing a bright light, and are they dangerous? (I'm meaning normal bright light conditions like your phone screen in a dark room, nothing drastic like the sun)
You should have Kurzgetsagt as a recommended channel or whatever it's called. Like add them along with the channels that are already on that list such as: Vsauce, It's Okay to be Smart, Crash Course, etc.. it's a great channel that's uploads are of high quality and they help explain a lot of difficult questions
The irony is that in floods a shortage of drinking water is usually one of the biggest problems. Run a clean tub full of water when you know the flood and power outage is coming. As one ages you get to choose. You can die of dehydration or lack of sleep.
Great now I'm thirsty
I peed before watching this video so😂
Seriously? I -was- going to watch the whole vid.. but the 'running want' bit triggered my full bladder. Accursed Pavlov! Also.. food? Fooood.
