Bruh my man *LITERALLY* drank water, what an absolute madlad

"Taste" was said 46 times in case anyone was wondering

Here's a fun water fact from a water plant operator: In the US, tap water is tested for turbidity, the amount of sediment present. It is measured in units labeled 'NTUs'. For water to be legal under EPA regulations in the US, that number AT MOST has to be 0.3 NTU or lower. The human eye cannot discern turbidity under 4.0 NTU, so water that looks absolutely clear and prefect to your eye could be 13 TIMES dirtier than a 'safe' level. Now here's the really messed up thing: BOTTLED water is regulated by the FDA, as a FOOD, not water. For bottled water, it's upper NTU limit is 5. FIVE. Bottled water can be almost 17 TIMES DIRTIER than the worst tap water allowed by law, and still pass as acceptable. Bottled water is covered under the same regulations as hotdogs, lol.

I never thought water could get ‘too clean’

Him at 3:03: “I’d say water tastes like water.” True.

I gained 6 brain cells after watching this video.

i drank a whole bottle of deionised water once and my whole tongue became inflamed and i couldn’t taste anything for about a day and a half. mad respect to The Action Lab for sacrificing his tongue for our curiosity!

I'm a retired chemical engineer. In one of the food plants in which I worked, we always used distilled or DI water out of the lab to make coffee, and everyone agreed it tasted far better than coffee made from the municipal water that we all drank and used at home. It's far more efficient at extracting the desirable flavonoids so the coffee was stronger but also less bitter.

He has a constant expression on his face similar to "hide the pain harold" meme

The action lab: ''Water has a specific taste... Id say it taste like water'' Me:''mmhhmm... very science''

Now I want to know if you can test the % “stuff” that’s in your saliva and make a bottle of water with the exact concentration to your specific saliva and see if *that* tastes like nothing

"makes my mouth feel a little dry " drinking THIS water seems like a curse LOL

He is blinking so much, it almost seems like he uses Morse code to tell us that he is being held hostage.

‘I’d say water tastes like water’ *every 60 seconds in Africa, a minute passes*

I used to drink DI water daily at work. To me it was sweet. Never once did it hurt my tounge or anything. It was great for making instant iced tea. Mixed almost instantly.

That tiny popping sound when the cell bursts... The empathy pains for that tiny cell are strong.

well who would have guess that pure water taste “dry”

Did we just come here to see this guy drink water

Wow! I had heard of the concept of “hungry” water possibly causing corrosion in engine cooling systems but not what it would do to a living organism. The water driving into the cell bit is truly mind blowing.

It’s actually been discovered that “starchy” is a 6th taste - in addition to the common 4 and umami

deionized water: -is dangerous to consume- TAL: d r i m k

"I'd say water tastes like water" mmhhmm...The floor is made out of...floor

When you said it made your mouth dryer and made you more thirsty I felt that, every time I drink certain bottled water brands my thirst gets so much worse. No I’m not talking about water +minerals or electrolytes I’m talking about name brand bottled water. P.S I won’t ever touch another bottle of arrowhead (bottled city water) again. I’ve drank better water out of the deep end at the public pool.

Wow. That was so cool. Once again, I’ve learned something interesting that I probably never would have even thought of if I hadn’t seen this. I always feel a little bit smarter after I watch one of your videos. Keep ‘em coming!

Me at my science teacher: but why would i ever want to learn about that? Me on my bed at 3AM:

I've often wondered if it really is dangerous to drink deionized water. Thank you for putting your own tongue on the line to test it!

you so deserve more than 3.5m subscribers, your videos are pretty much the back bone to many educational videos what are getting published on youtube recently!

Wow! I really didn't expect the affect of such a small amount to be so pronounced! Thanks for the demonstration. Never underestimate the power of water!

People that drink water at 4 AM: **It have some taste. And it taste good**

Water isn't tasteless because it tastes like water

Been a long time lurker without subscribing till now. Glad to see you're greatly improving your charisma on camera. Hope your channel keeps growing!

So what I am getting here is that we should start an experiment where someone tests their saliva for it's contents and then drinks a watermixture with the exact same ratio of minerals. It should then truly be tasteless to the person, shouldn't it?

"But it's not like it's burning my mouth" the next day "But it's like it's burning my mouth"

-Would you like to drink water?- *Which taste of water do you prefer?*

That burst sound was so satisfying!

Thanks for trying this experiment! I was curious

Nothing like watching a video at 3am in the morning about what water really tastes like

I need no proof. As a kid, i drunk about 1/4 liter of deionized water

This channel !!! fits my curiosity 100%

I took a creative writing course elective during undergrad and to expound on our descriptive abilities and use of imagery, the first assignment was to write a one page paper on "what water taste like". It was very difficult but I think that was the point.

I'm entertained by a man saying big words and drinking water

That's how I feel drinking school water fountains. Keeps me thirsty.

When I was working at construction during some hot days I ran out of water earlier than expected and nearest water dispenser was a long walk away, but there were always jugs of deionised/distilled water for the machinery. I drank loads of it for months almost every other day. Can't say I experienced any adverse effects at all. In fact normal water tasted weird afterwards. But I did drink it because I know you need regular water for the minerals in it. But props to the water, it did quench my thirst so did the job

Wow I just don’t know what to say, I’m just so glad I can learn such niche concepts and things like the taste of water and the factors that might change it not including altering the actual water.

I drink vegan water What about you? (Also sometimes i drink diet water)

"HMM. this tastes suspiciously like type 1 deionized pure water. I got cheated!"

Temperature actually has an interesting effect on taste too in my experience. Cold water and hot or warm water taste different imo, and I prefer a specific temperature most of the time.

This was really interesting, thanks! 😊

Is it just me or does his head look photoshopped on

Spit: salt Water: saltn’t

"so in order to quench my curiosity" 4:41 most of the time, the action lab makes their videos 1000% better by leaving in little jokes like that

One of the really cool differences is when you drink it after it's been sitting in a warm environment. Fill a bottle of tap water and another of distilled water and leave them in your car on a warm day. The tap water will taste gross, but the distilled water will still be delicious, even at a lukewarm temperature.

I got an ad about water in a water video. Damn it KZfaq.

Why do you look permanently confused?

Literally the best channel on youtube

This man is so good, we're watching his 7:38 video on drinking water.

Whoever's off camera pointing a gun at this guy and telling him to read his lines deserves a promotion

Does 100% Pure Water Have a Taste? Well..Kinda 1,218,597 views

Most interesting bit of cellular trivia I have ever heard.

Thank you for including umami. I am sorry for the pain you experienced.

I thought the lady had a bottle of mustard in her hand💀

We waited five minutes to watch a guy drink water. Hm.

This is so fascinating. I love your channel! Interesting fact: drinking a large enough volume of deionized water is lethal, or arguably, worse than lethal. The kidneys can only handle so much. Above that volume, serum sodium levels drop. Among the cells that are least tolerant of this hyponatremia/hypotonicity are brain cells, resulting in cytotoxic edema and cell death. This leads to coma and death. This process is especially severe in the brain stem (central pons). When this part of the pons dies from hyponatremic cytotoxic edema, the brain is permanently unable to communicate with the rest of the body, leading to "locked-in syndrome", which I envision as worse than death.

6:35 lol I appreciate that he added his own popping sound effect for the blood cell

I have a salt water aquarium so I make RODI (reverse osmosis, de-ionized) water for my fish. The reason is because the dry salt water mix that's used for creating new water for the aquarium has very specific measurements of trace minerals to match the ocean. If I mixed tap water with it, the resulting mixture would be way off. That said, I drink it sometimes and it's never bothered me. It's usually with other things though, so I think that makes a big difference. More importantly, I always use it for any time I have to mix a drink mix or coffee etc. It guarantees a consistent result, and probably has something to do with why people like my coffee so much lol (I never thought about it until writing this).

Can Kool Aid really taste good if you measure the sugar?

Wow. Next can you make a video explaining the difference between the purest water found in nature and bottled water. I've always wondered

Had a pretty similar experience, i even felt a similar sore feeling on my tongue and throat afterwards and this sensation of dryness but probably way less extreme than you're describing, when i once couldn't resist to try out how destilled water tastes like. And i gotta say i love that stuff's taste. I can't really describe it, but i think the biggest part that we (or at least I) are sensitive to are water hardness ( aka content of calciumoxide ) and sodium content, and i tend to find low hardness low sodium content (i can't reaaaally spot different salts objectively) to taste kinda "pure" and more refreshing. And with destilled water that was like the most intense version of this sensation that I ever tasted, which is kinda counter intuitive since (as you described) you can feel it "drying out your mouth" a little as you drink. Well.... Gotta resist this stuff now, didn't think it would be a bigger temptation after I tried it 😂

soooooo, what I learned from this: Drinking Water Is Dangerous...

Okay am I the only one in this world that literally loves the taste of melted ice. Not water... Melted ice. It has a completely different taste don't test me

I would enjoy a video from you explaining the best water to drink for health benefits

I love your videos!

A guy at the factory I worked at used to make Gatorade in the employee jug with the de-ionized water faucet in the lab used for running salt tests and such. I never noticed anything odd about its taste but I assume the Gatorade mix adequately saturated the water with impurities so it wouldn't have any affect on the body.

1:15 is this kind of like when you come back to your house after being gone on a long trip and you can smell the scent of your house for a bit when you first walk in? Not sure if anyone else knows what I’m talking about lol

i just watched a guy explain the taste of water for 7 minutes and 37 seconds. Great video imma leave a like.

It's sorta like particle-flow versus fluid-flow, when a specific type of water is introduced to the taste buds as fluid-flow, it would then appear to have a momentary effect on the molecular particle-flow regime within the taste buds. This momentary effect of being able to taste the water would be like discharging small capacitors locked in series to the brains connective-paths. When the taste-buds are triggered the particle-flow to the brain and back to the taste bud pre-amps begains neutralizing the potential difference. What's interesting to me is... What is that mechanism that allows taste buds to build back up that potential difference when the taste-buds are not being used? I love your videos ❤️

Lol I love how 7500 people watched a 7 and a half minute video about him basically just drinking water

We are used to drinking close to 0 ppm distilled water for extended periods of time. Then when I come back home the water here tastes extremely salty for a few weeks. 0ppm water is easier to drink when cold. When at room temp it feels more bitter.

It is the same like saying “im wondering how it feels to be on the top of a building, and also what would happen if I jumped off of it”.

Yes, the real danger from pure water is the excessive osmotic pressure it places on the wall of the cells it touches. By the time the water gets in the stomach, it contains enough impurities to become innocuous. But the tongue is exposed to a continuous stream of pure water, and therefore bears most of its damaging effect on the superficial cells. Which, as he correctly reports, are analogues to the effects of hot water. Half to one gram per liter of salt is enough to make deionised water innocuous. Note that saliva contains nine gram per liter of salt, the same as seawater...

Me: looks at thumbnail and sees him drinking PURE water Me: reads the thumbnail "DO NOT TRY THIS AT HOME" me: wtf it's just water

To be honest i haven't subscribed yet. I've been watching your channel for last 2-3 months without missing any video and now i fell like it worth the subscribe button! Great Job so far buddy.

you have the perfect sense of humour

Taste bud receptors work pretty much like endo-cannabinoid receptors in our body. While the receptors are "blocked" by something, you build tolerance. But that tolerance is simply the inability of the particles to access the receptors. When you increase dosage, you jampack them in, and get a higher reaction.

“Hmm, not bad” Famous last words of headless man

I wish you were my science teacher I would actually pay attention

Great video. can you also do a video about Distilled water. And is distilled water really bad for you?

Absolute fantastic video man, I was on board the entire time. Shout out for putting the ad at the end. Fucking ads.

this guy is lit, he’s the only guy who actually starts the video at 0:00.

I'm thirsty now

This was really interesting. I live in the middle of Sweden and drink a lot of tap water. I like the taste here, but if I go somewhere else in the country it tastes bad. I drank filtered water in another town and that was better. And forget about water in other countries, filtered or not it's disgusting. Especially in the US. Super metallic. I even had to order bottled water in a restaurant, it was as expensive as the wine bottle the other ones had. I don't drink much other things than water. Sometimes a soda or a flat flavoured water with minerals and vitamins.

So that's why when I dry my tongue it tastes salty there are very teeny tiny drops of saliva on my tongue Thank you for providing me such knowledge

Drinking absolutely pure water can kill you. All the water we normally drink - from taps, from bottles, from the garden hose - contains impurities which affect a property of water called tonicity. This is the ability of a solution to draw or repel water from ajacent solutions when separated by a membrane. Solutions that are hypertonic gain water, while hypotonic solutions lose water. Drinking water, which we usually think of as pure, really contains a whole mess of salts and sugars which make it slightly hypertonic. They also give water its taste. The cytoplasm in the cells of your body also have a tonicity. So, when they are exposed to hypertonic solutions, the cells themselves lose water and shrivel up. When they are in hypotonic solutions, they gain water, swelling up and bursting like a balloon. Absolutely pure water -with no impurities at all - is the most hypotonic solution. So, if you drink enough of it, your cells will start absorbing water. This disturbs the balance of electrolytes (electrically conductive ions) in your body. This is most seriously a problem in the brain, where water poisoning can lead to brain damage, coma and even death.

_Is this guy a meme yet lol_

At the end you probably also described why the mouth feels dry after drinking deionised water. Osmosis is what‘s happening there and it is the movement of solvent (water) to a point where the ion concentration is higher (your tongues cells). The body uses this phenomenon a lot, for example in the kidneys to reabsorb water so we don‘t have to drink 20 liters a day

Some people are not just a good team but still a great team

so that's why i can't taste my tongue...

5:00 when he drinks it

Guy on my boat drank DI water destined for a nuc reactor primary loop. Didn't kill him, but had side effects. Not only was his physical body injured, but also his career in submarines.

I'm not sure what "type 2" is but reactor plant coolant is pretty pure, and it tastes very dry, like a dry wine. It makes great hot chocolate or coffee though.
