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.
@LTNetjak municipal source bottled water is a minority. That's an easy answer because the largest brands do their own on site proprietary treatment and often cut local municipal supplies short. Biggest examples being Nestle, Desani, and Aquafia. Those are all factory treated and bottled just like a soda.
In Israel, in some areas tap water is actually desalinated sea water. The problem with it is not what it has, but what it doesn't have. Lots of health issues due to this.
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!
@@prasanna3378 this was back in high school? when i was young and immature, where my mates spray deionised water at each other. i was curious about the effects of deionised water on my body, so i drank the whole bottle. thank god i’m not like that now 😅
Nicholai looked it up, “While the brain has a limited capacity for regeneration, endogenous neural stem cells, as well as numerous pro-regenerative molecules, can participate in replacing and repairing damaged or diseased neurons and glial cells.”
It makes sense because the concentration inside your cells of different chemicals is lower than the water so it might leech those chemicals instead of providing them like normal water does
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.
I have a copper free line to my stainless steel water dispenser and made sure to get a stainless steel shut off valve. I put a reverse osmosis system in that is not as pure as the DI water plants that I made. Getting all copper and brass out of a system is the toughest part of installing a high purity system. But, I use only RO for drinking, making ice, cooking, and mixing drinks. My dispenser has one hot spigot and one cold spigot that are open to air. If I had used DI, it would have drawn CO2 from air and reduced its purity. So, I find RO is good enough. It is enough of a difference that I use no tap water.
@@meditative-keys works for tea and "Squinch" too. (Squinch is low cost Gatorade substitute that many large factories buy in bulk for serving on hot days). As soon as you add Squinch, even if it was 18.3 DI, it would be safe to drink because the squinch will definitely take it below 10k at instructed ratio on packet.
a bit jealous of that. lol sounds really tasty. I have a question for you Stephen. I tried this experiment myself with heavily distilled water before I saw this video and I sensed that the plastic leeched into the water. Can you allude to some classification of plastics that would point to a scale of would/wouldn't leech?
Funny thing is that well before I realized that water taste like water, I made it my mission in life to live forever and so far I have been successful.
@@skeetermcswagger0U812 my goal in life is to never stop breathing for more than 2 minutes. I failed once when I was a couple months old, but since then I've been doing pretty good if I do say so myself.
The Action Lab My tongue was pretty dry afterwards, haha. For my stomach, it wasn't really that bad at all. And thats pretty weird now that i'm older and know what pure water can do. I wouldn't recommend it tho, haha.
@@lewisho8114 pure H2O strips minerals off of anything it comes in contact with. At my old job we used Deionized water to clean computer parts since it'd that effective at striping impurities off the surface of the chips.
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.
Literally straight, untampered RO/DI water? Maybe just RO? If you mix it with something like instant iced tea, you're reionizing/remineralizing it and it's no longer DI water. Water's a heck of a solvent, so RO/DI water, lacking any ions, would dissolve high surface area things like powders very, very quickly.
@@jacobcohen3280 Funny thing - metallic is closer to “salty”, chemically speaking - and in terms of taste receptor binding. And what we think of as the actual taste of metal (like of coins and blood) is a completely different substance that is involved with reaction against redox with metals themselves.
@@xanderlommen7u770 THAT’S the one! Thank you! I remember reading about it in a few publications long ago, and then NileRed did a vid on it like a year ago as well. :-) Yeah, it’s actually the oxidation of the greasy oils from the skin on the metal that gives it that metal smell and taste, if I recall.
Most likely cos he drank from a plastic bottle of deionized water that you can purchase from a petrol station lol I use a distiller. The water has no taste, and viscosity feels different on the tongue. Water feels thinner. It's lovely to drink. Tap water is disgusting in comparison.
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.
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?
If you made a substance with the exact same concentration of types of atoms as your saliva… Wouldn’t you have just made your saliva? In a round about way you would’ve done nothing at all.
It'd be extremely difficult to replicate saliva because it has a lot of biological components like enzymes and proteins. Not to mention saliva is a lot thicker than plain water so it'd be like drinking sludge lmao
i speak morse code, his blinks are saying "please help i am being taken hostage by the cameraman, he is holding a gunpoint and forcing me to say this stuff"
Why would that happen? I mean what does RU-vid think? That you are interested in drinking water because you watch a video about it? I mean ITS WATER, EVERYONE DRINKS WATER but me, I drink oil.
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.
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
Most elements become denser when they cool, but water becomes less dense due to the unique way hydrogen atoms behave. It's this lack of density that allows water to accumulate more oxygen as it freezes. The difference in taste in freshly melted water opposed to normal water has to do with this difference in oxygen consistency. It's the same reason ice floats, by the way.
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).
@@matty_isthemotto note this is over simplifyed the problem is a problem of concentration of ions and when there is a large difference ions the one with less ions will essentially rip the some of the others out from something however there are only certain things that can have the ions ripped out unforchinatly the human body or any biological body for that matter can have its ions ripped out however adding salt increases the ion amount and thus prevents this from happening
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
Your food should make up for the lack of minerals. It's a bit like people who drink loads of water during exercise losing too much salt. Just put some salt back. If you just go on a distilled deionised water fast then maybe.
@@saeedahmedmahin1593 Also known as dihydrogen monoxide. Still.... Pure water kills you pretty easily. The colloquial water we chug down, just like alcohol, is chemically speaking a solution that's only good for you in moderation. Drinking water with absolutely no salt in it is about the same as drinking sea water.
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.
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.
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.
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.
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.
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
Similar. From what I have read the olfactory receptors take time to reset after they have been excited by binding to a molecule. Since there are only a finite amount of the different types, you can effectively desensitize your sense of smell with constant stimulation or over stimulation. It has a benefit of allowing new smells to be picked out easier as they won't be masked by the environment. Such as finding food or sensing danger like smoke. There are several noxious gasses that if you smell it, it means danger but if the smell vanishes it can mean the concentration has increased drastically and mediate danger. Hydrogen Sulphide for example.
Yeah, instead of spending a year on that "WHAT'S up everyone, this is The Action Lab hitting it up with a brand new video, oh and by the way don't forget to smash that Like button and subscribe!" crap.
_ssaevol no, you wish my former science teacher was yours. She hands out candy almost every week, and she lets us sleep in class. Plus I got to teach a class once, and she is very polite, and she doesn’t bring politics into mind ever. But yes, I would pay attention too.
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.
True - not recommended to drink from sun baked plastic, but true. Tap water has bacteria that grows and generates different gasses and biproducts so it will change in taste over distilled.
@@Darkcell459 BUT, putting water in clear 2 liter bottles and leaving it in the sun all day has saved millions of lives in the 3rd world. It's cheap and easy UV disinfection. The sun packs enough UV-C light punch over a day that even very questionable water is sterilized and safe to drink, no filters or electricity needed. ALSO, for rehydration, you want water as close to body temp as possible, you can't absorb/use water you intake until it is warmed to body temp.
Everyone has different sense of taste, but warm distilled water is gross because it doesn't have much actual taste to it. But you can become use to and even come to enjoy anything. We like what we eat (or drink) everything is an acquired taste. Some things just take more acquiring than others.
@@Darkcell459 Tap water should still have enough Chlorine residual to deal with any bacterial growth, but water treatment is not a static process, and the chemical process don't stop, so, tap water has a shelf life so to speak. Putting it in a jug and warming it for several hours will definitely accelerate that process. So the chemical composition will be different after a time, it isn't bacteria so much.
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.
LOL just hit that subscribe button!!! xD Makes it so much easier to find his channel and latest videos, you just write lab and get Cody's and Action right at the top! And don't forget the bell!
You know, you're comment is sincerely appreciated. It's pretty much the only comment with substance. Every single other comment is an aspiring edge lord attempting to meme but failing.
The interesting part to know would be, what above totally pure water is considered drinking water. A 0.001% concentration of sodium chloride, magnesium chloride, potassium chloride, calcium chloride and zinc? or do you need zinc? Do you need all those salts, or only a couple?
I live in "upstate" New York and we have a brand of water with added minerals called Dasani, that I don't like, but there is also a local brand, supposedly derived from a spring in Saratoga. I like the Saratoga water much better, and I also like my local tap water from an aquifer. I think we are habituate to the water we most often drink.
There is also a significant difference in taste according to the PH balance of water. I figured out why I hate certain brands of bottled water, and even my local tap water because it turns out PH can significantly affect taste. A lot of water sources can also contain a high amount of ammonia which can significantly affect taste, and when I personally have drank water high in ammonia (usually tap water) i end up with heart burn or a stomach ache.
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!
I used to work in a lab. We had a special faucet at the sink that dispensed deionized water. It was rather flat and what taste it had seemed to come from the tubing that supplied it.
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.
My favorite water in the US is Fiji, there's no other water that tastes better for me. I imagine drinking deionized water would feel like when you eat too much pineapple and your tongue is scalded.
@@dareuhhh Well, taste is very subjective 😆 My wife loves smart water, and doesn't like Fiji that much either, but for me it tastes like the spring water my late grandpa used to give us in Mexico.
I did this out of curiosity a few years ago when I was working in a lab. I must have consumed a bit more than you, because I recall that feeling on my tongue and into my throat. I was waiting for your reaction.
@The Action Lab - I love your videos so here's a quick tip that might help make them just a bit better. When framing your shot, instead of putting your head in the middle of the screen frame it toward the top. All the dead space above your head is not only wasted space but creates a less enjoyable experience for the viewer. Consider a few other "talking head" videos on youtube for examples that will show you the industry standard is to have very little space above the head. Given that many if not most of our viewers on youtube are using small screens (like mobile) wasted space makes a big difference. Keep doing what you're doing! We really enjoy it! You have such interesting video ideas.
I searched for this bcs i read an article years ago about the super pure water in Japan's huge neutrino detector where one man reported that touching the water while cleaning it made him itch and also a spanner that had dropped into the tank completely dissolved leaving just a stain on the bottom. I learn so much from your channel. Amazing stuff. Good job.
Deionized water still has some organic impurities. Also it may taste as impurities from plastic container. When I drink distilled water from a plastic container, sometimes I taste plastic
Mr. Vlad well, he is amazing and his channel is really good. I would like to see a video in which he leaves a question for the viewers. He explains everything and that's great but it's good when something makes you think on your own. He could make some collabs with other great channels like physics girl, smarter every day, Cody's lab... I can't compare them, they are just great at what they do in every video but the Action Lab is among the best channels, no doubt about it! I love their passion for learning and explaining and discovering... On the Action Lab... I can't recall one video that didn't blow my mind with something everyday common, normal, but that I didn't know or thought and he even makes experiments out of it!
