Did he just explain the origin of the stereotype of the drunken sailor?
cfltheman yes
cfltheman Yeah like we cant just skip over that, it should be a video of it's own

Is there a science behind why we sometimes talk in a different vocal pitch when around strangers or acquaintances?
Dawn Wayfinder I think it's to do with confidence levels.
It might related to your anxiety levels.
Dawn Wayfinder pitching down: confident/dominant
flat: eh/whatever
pitching up: apprehensive/trying to get something
Xphoes he just explained why we do it...wow
Dawn Wayfinder People tend to talk in a higher pitch as a result of talking faster, and people talk slower when they're talking to strangers, because they're weighing their words more carefully. That's just my guess anyway.
Another question is why we talk in such a high pitch when we're talking to babies or animals. I wonder if there's an evolutionary purpose, or if we're just imitating behavior we've seen in others.
It's not the water that expires it's the bottle.

nightshade? is it a type of water??? That reminds me
I still need to try that amonia and bleach bath someone suggested to me last week.
Sounds yummy!
Firetail Taevarth ARE YOU SURE
I don't know if it's his glasses or his eyes but they look very far apart...
AceOfSpades yep
AceOfSpades he has a lazy eye
ah right
AceOfSpades Does it matter?

I can't stop staring at his eyes...
sfh ooooouuuu 😂😂😂

Bro why u so rude
I was asking my husband this question on holiday a couple of weeks ago! According to the bottle, the water I was drinking had fell as rain 5000 years ago and had been filtered through rocks etc and yet it had a best before date of Dec 2016! I was intrigued to say the least and now I know!
Lol
🤣
I reckon most of what I taste in the water from leaving it standing overnight is dust because when I put a tissue over it I don't get the odd taste.
I think some of it is also because the trace chlorine evaporates off overnight as well. But the dust thing makes sense as well.
water expire because the longer it sits in your plastic bottle, that bottle will comintation with BPA
Fantastic presentation. It's one of those questions that frequently occurred to me but never urgent enough for me to investigate.
this channel gives me ideas for my science vids thanks Dnews
Some water gives me horrible heartburn, but most does not.
I think its due to some bottled water being basic and others are acidic
Same here.
Great vid! Thanks!

I really wish you guys would add annotations to your other videos that work on TH-cam mobile, or link to the other videos in the description since I watch 98% if these videos on my phone
Why do so many people say they like the "taste" of cold water better than warm water? Is it just psychological?
My guess is that you taste cold things less than you taste warm things and they don't like the taste of water period, so they like the water that tastes less (ie cold water).
I don't know for sure this is the explanation but I remember reading something a while back about how hot food/drink triggers stronger taste response from your taste buds, and it mentioned as examples that drinking your favorite iced cream warm and melted is sickly sweet while drinking your favorite beer warm tastes far more bitter than served cold. It also used as examples for people using heat to enhance flavor things like coffee, tea which people heat to enhance the bitterness, and hot chocolate which people heat to enhance the sweetness. It almost seems obvious in hindsight - hot stuff tastes more than cold stuff, and that's why those cold leftovers don't taste nearly as good as if it was warmed up to the point you can taste it more.
StreakyBaconMan That was actually pretty interesting I learned something, cool !! 😄
"I'd love a warm beer after work"
Have you ever gotten sick from water? Yes. 1st grade, field day, hot outside, and water. I just assumed we could drink the water and nothing would happen. So I drank and drank. Few minutes later I puked it all up. It wasn't very fun.
I got cholera from a school tap. Was sick for 2 weeks #neveragain
probably not the water that caused you to yak, but the impact of the exercise
StevenGaspard also comes to mind that when ur body show signs that it wants to throw up, drinking water provokes some reaction that actually helps to throw up, i learn that if the body urges to throw up, dont drink water till the urges dissapear
It was just the heat that caused it
poop
This channel should put the link of the video they are promoting so that we (mobile users) could see it!
have u guys made a video about protein powder? or ike suplements and stuffs?
I wonder if the main problem about bottled water is being exposed to direct sun light, why isn't out there a black bottle? Or with some material/color that diminishes the light comming through?
Of course there is the marketing side of the question, transparent means purity, but.. water could have nice designs too!
Great shirt, man...
Hi, does drinking water from a silver cup or copper cup make the water healthier with more minerals?
It looks like he wearing a cap he got shadow on his eyes
You can probably see the microns with those glasses
2:09 Did Julian pronounce "early" as "er-lai"? That is an unusual pronounciation.
Its a song about sailors and is pronouced ear li 😉
Slide84rik Is it old English and he made it into a pun or something?
GuyWithAnAmazingHat Look up on youtube "what do you do with a drunken sailor?" - it's an old sea shanty originating in the 18th century and they pronounce the word "er-lai" so he's making a reference to this song based on the topic at 2:09
I see thanks, I was thinking it was too specific to be some kind of mistake and indeed it is a reference.
GuyWithAnAmazingHat That is one amazing hat.
Thanks sid
The video is 3:14 in length... Pi is everywhere!!! XP

The expiration date on the water bottle is actually for the plastic becuase it decays over a long period of time, or will start to (most is usually about 2 years from the time you bought it), but not the water it self
Thanks for the good news
I drink water.
What is water?
same
So, the bottled water which is several years past the expiration date is still safe, and will continue to be safe forever?
Law of constant composition: the properties and elemental components of a pure substance will always remain the same, so yes, water (a pure substance) NEVER expires.
J Salas But it is not pure, it is in constant contact with the plastic which releases certain chemicals in the water like the video said.
Yeah, you'll get a lovely dose of BPA and probably feel sickly, so don't drink old bottled water.
J Salas Water isn't a pure elemental substance, it is a molecular substance.
Interesting about the expiration date but you guys are right...the plastic leeching into the water...I can taste it at times.
Hi Dnews...Just read a news regarding harmful effects of BPA when plastic food container is used for heating in microwave...Can you please shed some more details on it as this is done by so many people around the world....
When storing water, do you need it put the water purifiers/additives or is all that a gimmick to take your money, please answer. Much appreciated.
pesticide can go through bottle? so plastic have holes small enough for pesticide to pass but h20 is too big?
I left a Polly Pocket mini aquarium abandoned in my basement for 6 years (cause I completely forgot about it) and the water didn't really change it did look more blurrier inside though
I heard somewhere that the expiry date on water bottles are the expiry dates of the bottles.
There law in New Jersey stated that all food products must have an expiration date on the label, and that the date could not be more than two years from the day it was packaged. So it applied to bottled water, but no one was really thinking about the water when they wrote the law.
I have a 2 gallon jug that I keep next to my desk and drink from (by pouring it into a cup), since I'm lazy and it's easier to fill up a jug every few days than to fill a cup or water bottle every few hours. I refill it with water from the tap.
Could this be a bad thing to do? Am I exposing myself to harmful bacteria by keeping water within the same jug for what's now been about a year?
what is the hard water, and which are the effects in the human body? my girlfriend lives in southern part of Chile, and i live in the middle of the country, the thing is she usually get sick when she stay in my city, she said than the water taste different and this may be the reason of his sickness, why could it be?
Yes! Julian! ♥️ I'm happy I'm seeing him more often. :)
Is this the same for lemonade?
While working at the airport found a WW2 survival bag marked 1947, it had several sealed cans of water, we opened and drank some it was fine.
Seeker, I am thankful for what you taught me about water today.
In water contained in a plastic bottle, the plastic degrades over time. Air can't get through plastic, but for this reason, they still have expiry dates.
poop
hey julian, is distilled water really safe to drink????????????????????????????????????????????????????????????????????
please answer as im not finding reliable answers anywhere.
I just want to know.. if i kept a full water bottle in my bag how long i can drik it. Without harm.
So how long could you continue to reuse a bottled water bottle. Ie buying bottled water then refilling it from the tap. A couple of days, a week? This is assuming you wash it out regularly.
Why do gallon jugs of water, if kept for a long time, either expand or contract (I've seen both) even though they are protected from temperature changes and sunlight?
If you were to drink from a water bottle, cap it, forget about it and find it a few days later, would the bacteria from your mouth have multiplied inside the bottle sufficiently to foul the water?
I personally switch to Coca Cola after drinking water for 7 years
Gavin Hersom my teacher said coca cola slowly kills us
Eubian Cueto well science shows 100% of people who drink water die within 150 years
lol
A man was lives to 256 years old
And what do you think coke is made of...water !!
When you live in Finland and you can drink from the tap! Ha!
Fin.
I am not sorry
no never, unless it has bacteria or parasites
just wondering about the expiry date on the bottled water .. i had read a fact that the expiry date is of the bottle not of the water ..
so the water inside the bottled water is drink able even after the expiry date ?
Expiration date is for the bottle, not the water itself, because plastic will decay overtime (but the water is already leaking and turn into vapor long before the plastic bottle gone decayed)
Wait, so BPA coming from bottles, and storing permeable bottles in warehouses are not causes for concern?
my mom and dad: WATER DOSENT CHANGE ITS TASTE.
me: uh..sure..
But when you use a plastic bottle and put tap water in it how long can you drink from it?
talking about water, how to know that the water we drink is healthy? example like tap water, boiled water, ro water (reverse osmosis) and etc?
Thanks
A friend of mine would always say water would give him a guts ache and so he always added cordial and had soft drinks. He ended up with bad diabeities.
So what if i fill up a Water bottle and put it in the fridge? How long would it be okay for?
i have got a big bottle of water and it has green stuff growing in it. algie i think. it took 5 years, and its still growing.
NYC was voted to have the best tasting tap water in the country. Sourced in the Catskill Mountains, it's probably cleaner than most bottled water.
So a water bottle that's been open and left in the fridge closed is OK if it's there for a while?
If you refer to another video please list it in the desceiption (sorry for bad english)
I love this guy!

_Everybody chillin' till the water gets lumpy_
If kept in a plastic container, the plastic is leeched into the water. I had some jugs of pure water from over a year ago, I asked around to see if I should drink them, and the general consensus was to dump them out.
poop
I would love to know the science behind yeast!
What about acidic water vs alkaline water? Is one healthier than the other or is there no real difference for human consumption?
Thomas Greer Water is always neutral. You probably add something to water. You know, the PhD scale revolves around water as pure H2o is the centre.

I am pretty late with this comment/question.. but is it Safe to drink Reboiled Water?.. there are tons if misconception out there :/
Since we are on the topic of liquid expiration does alcohol expires mainly talking about hard liquor like brandy, Hennessey, scotch and what not
so how about boiling water and then putting it in the freezer to cool it and then drink it. does it make it safer does it change the acidity in it. you know what I'm trying to say.
poop
bu. bu. bu... that's my favourite place to store water,
on a sunny field near the pesticide factory.
When I was little my mum would fill a sippy cup up for me at night, in the morning I would make her change the water in it because I would cry and say it taste yucky, I've been that way since XD I hate water when it stays out for so long
Does whitening toothpaste actually work?
I thought that the expiration dates are for the water bottles, not for the water. I just heard of it so I can't really confirm it.
Was seriously thinking this topic to myself the other day.
Me too
Can l store Tap-Wahtuh, Me Hearty? ...and If yes, Zen how long fer?
How much would the sea level drop if all of the animals and biomass was taken out?
How should we can store water for long periods in underground
Good video.

Valios RW Maybe...maybe not. I can´t be sure. I´ll have to think about it some more. This question merits more thought...uh...mmhhh. Some coffee might speed up this solution...pffff...I´m not getting it. Again why are we all watching this video to begin with???
So what was the expiry date on water bottles for? Kinda missed that part
+peaaanuuutz it's for the plastic
Sailors were at sea for months at a time. Is it really hypothetically possible for the body to function on beer and rum instead of water for months?
I drink water from streams when I go hiking in the mountains. So far i haven't gotten sick.
Your next doctor visit. Get tested for candida or parasites. Let us know 👍
Well, im from germany. Ive never seen bottledwater with an expiration date and ive drank water that was months old and was fine. Also in most 1st world countries you can drink tapwater without any profit. Here tapwater is actually one of the best to drink
Why do we suffer throat problems after drinking water from a different source than usually
Question: what prescription are your bifocals?
how do you know if the plastic is BPA free or not?
I would love it if DNEWS could expand upon this topic especially regarding chemicals from a plastic bottle that can get into the water. I don't drink bottled water for many reasons including my concern over what chemicals from the bottle get into the water. Literally every single (plastic) bottle of water that I've frank has had some type of plastic - like smell and/or taste to it regardless of how new or old the bottle is. I hope DNEWS can look into this further and examine all the chemicals that come from plastic bottles. Thank you.
thanks e.t.
Well it can turn 'bad' to drink in some cases. Water can go through a process called stagnation and become toxic with bacteria.
Every week I de-chlorinate my drinking water from the tap. I fill a 5 gallon, sterile bucket and let it sit 24 hours before drinking. I keep it covered by a cloth, so the gases can escape. I also store the bucket in a cool, dark place and after a week it's still okay to drink, but that's just when some algae can be seen at the bottom.

Why I do not drink water(I am talking about weeks, such as holiday) and I don't feel thirsty? My cousin and my mom do not hydrate themselves much especially my mom which do not drink water like me.
I filled empty soda bottle with water while on long trip. I had other things to drink first and I didn't need to drink the water during the trip. Bottle was left in my backpack and week later when I came home there was something green moss like stuff in the bottle.
I was on road so I didn't have time to start cleaning the bottle. It's not a habit of mine.
A doctor told me to never drink bottled water left in a car over 4 hours because the plastic has leeched into the water.

No one is that dumb. Bye troll. Read more and stop posting bullshit.
You're the troll who has to post on other people's comments because no one is interested in your posts. That's why you have to create new faceless accounts each month and have no followers.
EH CBunny Yes; it has that funny after-taste.
It also causes cancer

Is cloudy water dangerous?
When explaining that shellfish need carbonate, not bicarbonate, you showed a crab, which is a crustacean, not a mollusk. In our common language, we refer to both as "shellfish", but they are radically different. The shells of mollusks are the ones made of calcium carbonate; the shells of crustaceans are dominantly chitin, with calcium carbonate as a secondary component in some crustacean shells. Shrimp shells, I suspect, have little if any calcium carbonate, and their shells are not comparable to those of mollusks such as clams and oysters, but they're still called "shell fish".
Look out, Wal-Mart has been known to sell bottles of curdled water.
sailors put silver into water casks to avoid bacteria growth.
