Pure water is still very slightly conductive due to autoprotolysis (meaning there is a chance that the H2O molecule splits up into a proton H+ and a hydroxide ion OH-), but yes, the resulting conductivity is almost insignificant compared to non-deionized water. The problem with pure water is that it can't be in contact with anything it might leach ions from (ex.: sodium from glass, metal ions from metallic parts, carbonate from CO2 in the air) or it's not going to stay an insulator for long. Fluorocarbons (see Thoisoi's "Dry Water" video about fluoroketones) are probably a safer choice.
I'd say water purification is one of the technologies with the most positive impact on quality of life ever. Only when travelling abroad, realizing that all over Italy tap water tastes like chlorine water from a public swimming pool, I could understand how invaluable it is to have such high drinking water quality as in Germany. Clean water to every home at all times. I can't imagine how many lives have been saved by clean water preventing disease.
I live in the US and I filter all of my water that goes into my body. My soda stream water is filtered and filled in bottles, so when I make my own soda its made with filtered water. Any time I cook I use filtered water. Only time I come in contact with unfiltered tap water is when washing my hands and taking a shower.
@@alfredharrison597 which state do you live in? What are the regulations for allowed concentrations for harmful components and what type of filter do you use? does your filter achieve any extra filtration after whatever limits for drinking water your country/state has set?
Beer is disgusting period, you all forced yourselves to like it. Otherwise non-alcoholic beer would be a popular drink. Always just tastes like soapy dish water. Basically just pure bitterness diluted with piss. I'll never understand why people like it, most people must barely taste bitterness. Because to me bitterness is the most disgusting taste possible. Yet from I understand the bitterness comes from the added flavor to beer. Like why flavor your beer with the most disgusting bitter stuff you can find? Like hops is a flavor, not the main ingredient. But it's the only flavor they add to beer anymore. Plus beer barely gets you drunk. Like why drink nasty stuff for hours when you can just take a couple shots and then drink something that tastes good.

Very interesting, a friend of mine has been working on similar techniques both using osmosis and semi-permeable filters at the University of Twente. By the way, did you know that in the 'Amsterdamse Waterleidingduinen' (a type of dune and forest area) they pump Amsterdam city's waste water through the dunes and collect it at a lower point. The sand in the dunes together with microbes and other things found in the soil, help with filtering out all the unwanted particles resulting in the cleanest, softest water available across the entire country. Very interesting!
@@knrz2562 Nope, it's not desalination since we do not use salt water. It's pre-filtered water (where they remove bigger particles and debris by various mechanical methods and precipitation techniques with big circular basins) and after that the sewage is pumped through the dunes. So the sewage is pumped from Amsterdam, all the way 25km down to the dunes, then filtered through these dunes, and collected at the bottom. After that, the clean water is pumped back all the way to Amsterdam and surrounding cities.
@@garrysekelli6776 "Is tap water safe to drink in the Netherlands? Good news: tap water is totally safe to drink in the Netherlands, especially in Amsterdam where the tap water is often better quality than bottled water. In fact, Dutch tap water is the second highest quality in Europe, scoring 7.1 out of 10 in a study."
My favourite part of the video was when you talked in English 'live' towards the end. I realised that to do this on every video, you would have to make two, therefore putting twice the effort in and it's just not practical. I think I watch your videos more than any others on YT, and I like lots of others thought WTF!? When you had the digital voiceover, quite a while back now ; so glad you decided to voice them yourself, making them more 'real' Keep up the excellent work.
That forward osmosis filter looks exactly like the filters we use to clean blood in hemodialysis. The blood flows inside those little white straws and outside flows an electrolyte solution. Interestingly to mix the electrolyte solution (dialysate), we use the kind of intense water filtration systems seen in this video. We have a water softener followed by a dual carbon tank filter, followed by reverse osmosis. This water is used to mix a sodium bicarbonate solution in one tank and an acidic electrolyte solution in another. Those tanks feed the dialysis machines, which perform the final mixing based on whatever the doctor prescribed for that patient. Very cool video!
Also, several people here noted that the alcohol passed through the filter, and I wondered about that too. But then I think..if CH3-CH2OH can pass through... _did other small organics from the first yellow run pass through too???!_ 8")
the difference is between solvent and solute. most of the organics in the Thames will be in solute form as organic salts. these will be filtered into the flask that also has the non organic salts. but yes, there will also be other solvents in the water, like alcohol, ether, glycols, etc that will end up in the jar with the "purified" water. This is why typically after using this type of filtration, or mechanical filtration, you typically follow that up with something that will absorb solvents other than water, like carbon. but, in the Thames, it is likely that there is a relatively low concentration of organic solvents that would be dangerous, and even less likely that there would be dangerous solvents in enough amounts to harm anyone given the tiny amount he drank, even if it was entirely unfiltered.
@@thomasneal9291 oh yes yes, sorry, I meant the pee Particularly the urea which is polar and not all that much bigger than ethanol. I mean it's a "solute" since it's solid at that temperature normally, but it's not ionic (like uric acid would be) so does it matter? Sugar obviously doesn't get through, but that's because the molecule is too big right? So then what actual maximum size or attributes define the semipermeability of the membrane if C2H6O can get through but C6H12O6 can't? (or did the sugar have to be a disaccharide and monosaccharides _would_ have gone through??) There's a lot of info I'd need before I recreated the experiment and drank pee filtered solely with single-stage osmosis XD (I mean if someone was drunk, do they pee out acetaldehyde? And if they were using this on mars or a submarine, would they just be drunk forever if they ever drank a can of booze? XD Probably it would go away but still, I'd think more research would be needed to really use it frequently, much less all the time.) (Or for chemistry! like my idea of using (NH4)2CO3 as the salt instead of the sugar, then electrolyzing it to avoid needing to overcome the latent heat of vaporization of water to reconcentrate the "clean" side of the forward-osmosis filter :) ) (Although that could work for drinking water too, possibly) (Either way you'd need to be sure of what could come through the membrane!) (Good luck though I guess since he said the membrane was a "corporate/proprietary trade secret" or something X") )
this was awesome, again I say you're legendary - you deserve a TON more subs and views. The main fact that you were wearing a yellow shirt, while drinking a yellow liquid, that you made from another yellow liquid that came out of you.... Its crazy! :D
Water management is one of my best subjects. You need filter material, disfectant chlorine. This is a good video. In wild areas a special filter that removes 99.99 percent impurities but not toxins from algaee in a lake.
Microplastics are another issue as they decompose very slowly - I've seen a catalytic Fenton reaction (hydrogen peroxide + ferrous salt) that can eat away even microplastics - it gets expensive at scale.
You drank water from the Thames? Been nice knowing you 😉. I've seen what they dump in it first hand - like sewage in the River Fleet which empties into the Thames at the north end of Blackfriars Bridge.
i have only read a few comments and decided to make a PSA here. Do not drink large amounts of pure water. It has the ability to draw a hazardous amount of salt/electrolytes from your body. (this is not good)
As a Water Utility Worker. 100% on board. The World needs safe drinking water. More videos. I would like to see videos using Alum as the flocculant and Ozone to kill off all Bacteria and viruses. Chlorine is important for most water utilities in the USA Because you can test and know the water is safe if there is a residual left in the water. There is a major science in balancing the amount of chlorine to the water. The public doesn't care about water quality until they are without. Clean drinking water needs to be taught in schools in America.
There’s an old saying in chemistry… “Milk, milk, lemonade, around the back fudge is….” Uhmm, never mind. Anyway, wonderful video! To take the closed-loop space theme one step further, it would be cool to see if Urea crystals could have been obtained from the concentrated urine solution, as that is an important fertilizer component.
It's possible ethanol is a small enough molecule to pass through the membrane with water. Then it would have the same forward osmosis as water because of the concentration is 0 in the water solution.
Nifty. Many many years ago(mid 70's ish) on PBS TV I seen a device that allegedly made sea water drinkable. Apparently it forced water through some sort of flat but thick plastic disk-like filter under VERY high pressures(if my memory serves me). It looked kind of like a pair of very large bolt cutters with very long metal handles. & If I remember correctly it took a few full squeezes over a few minutes just to get like a small cup(maybe 4ish oz). I don't know much about chemistry at all though I'm sure such a device could filter water but to remove salt too idk ! Has anyone ever seen this too or anything like it ? Now I'm wondering if it was just a total farce. It was on a "semi-reputable" show like Nat Geo though I do not remember for sure.
I have very vague recollections of this. I think it was a mechanical form of a reverse osmosis filter. The pressure was created by human input rather than by a water pump.
Yes, pretty much standard now on lifeboats, as that way there is no need to put a lot of bottled water in them, just a pair of manual pumps and the membrane units, saving space and weight in the lifeboat. Needs a lot of work to get water, but at least will last a good number of years in use.
@@SeanBZA Cool ! It seemed pretty legit at the time, but I never really seen it or anything quite like it before or even since. I suppose I'll just have to check out some modern life boat equipment. 👍
@@GothBoyUK Yup, definitely 100% human powered but the leverage sure looked big enough for it to seem legit for survival. Sean below says they're pretty standard now. I need to check them out. 👍
There once was a sailing boat that capsized in the canal the sailor was stuck in the capsized boat for three weeks and was finally discovered because a sonar picked up the sound of the guy continuously pumping the hand operated reverse osmosis filter.
Some islands with old mines are using RO membranes, but cut the cost of the power by putting the RO membranes deep in the mine, so the pressure of the water in there, fed from the salt water up top down pipes to and from the membrane, means most of the compression is done by gravity, with pumps only having to provide a small bit more and circulate the brine out. The fresh water volume is smaller, so a lower power pump can easily lift it up to tanks on the surface. Does require deep mines that do not flood though, or you make a unit that can be lowered down to where the pressure is high enough, and have a fresh water pump in the pipe to the surface providing the pressure differential, and a cheap pump to circulate the brine side out.
Woah that was interesting ! After chemistry my second hobby is... caving and quarries. I cant say I ever thought of that. Most of the plumbing I've seen underground was either in mushroom farms or crazy people bringing water from one place to another to grow stalagtatites & stalagmites. Some bunkers I visited still had running water after 50 years: under a mountain, gathering moisture from the northern slope and collecting into a tank above the bunker. Can you suggest any links or keywords so I can research this a bit more ?
@@herrhaber9076 I worked out in 1977 and presented at a meeting in 1978 that you can do total desalination of seawater with just the help of gravity, and no pumps at all... but when there is that much salt to be removed, a rather great depth is required, 11 km, like in the Challenger Deep of the Mariana Trench. There was some discussion of this on Halfbakery a few years ago, where many people were confused by the idea.
@@YodaWhat Thank you ! Wow, 11km is a lot. So... it's not really practical right ? I assumed this depends on the diameter of the pipe since a larger pipe would hold more water (therefore more pressure). Would this assumption be wrong ? I am not an engineer :)
@@herrhaber9076 Diameter of the pipe does not affect the basic principle, only the height is important for the yes/no question of "Will it self-operate?" Where pipe diameter would matter is the production rate, because a small pipe would have more flow resistance. Also, the pipe needs to withstand a crushing force from the outside, because throughout most of its height, the column of fresh water will be at somewhat lower pressure than the seawater outside the pipe.

Ok the water filter with the bag he used it the bomb when I was homeless 2 years ago I bought one so I could have water even if I couldn't buy it stack 2 of them together for a super effective filter to filter urine
I’d be reluctant to drink even the tap water in London - yuck! Living in Scotland, I’ve been spoiled by the lovely soft water up here. No scummy kettles either.
An interesting topic. I have a ZeroWater water filter from USA and it uses the resin and activated charcoal . I have been considering cutting the filters open (as I have several used now) and seeing if I can clean the components and reuse them . Is this possible?
In Nuclear power plants they use the same technology to get very pure water. To reuse the resin they have to do backflush with chemicals that will remove the built up impurities from the resin. It is not something that's worthwhile on a small scale.
Explanation: It is jsut an industrial copy of the natural Moringa seeds powder, that is the origin of this effect. Look for out open source water filter and you will understand what we mean.

Now I'm wondering if it was just a total farce. It was on a "semi-reputable" show like Nat Geo though I do not remember for sure.
I have very vague recollections of this. I think it was a mechanical form of a reverse osmosis filter. The pressure was created by human input rather than by a water pump.
Yes, pretty much standard now on lifeboats, as that way there is no need to put a lot of bottled water in them, just a pair of manual pumps and the membrane units, saving space and weight in the lifeboat. Needs a lot of work to get water, but at least will last a good number of years in use.
@@SeanBZA Cool ! It seemed pretty legit at the time, but I never really seen it or anything quite like it before or even since. I suppose I'll just have to check out some modern life boat equipment. 👍
@@GothBoyUK Yup, definitely 100% human powered but the leverage sure looked big enough for it to seem legit for survival. Sean below says they're pretty standard now. I need to check them out. 👍
There once was a sailing boat that capsized in the canal the sailor was stuck in the capsized boat for three weeks and was finally discovered because a sonar picked up the sound of the guy continuously pumping the hand operated reverse osmosis filter.
Some islands with old mines are using RO membranes, but cut the cost of the power by putting the RO membranes deep in the mine, so the pressure of the water in there, fed from the salt water up top down pipes to and from the membrane, means most of the compression is done by gravity, with pumps only having to provide a small bit more and circulate the brine out. The fresh water volume is smaller, so a lower power pump can easily lift it up to tanks on the surface. Does require deep mines that do not flood though, or you make a unit that can be lowered down to where the pressure is high enough, and have a fresh water pump in the pipe to the surface providing the pressure differential, and a cheap pump to circulate the brine side out.
Woah that was interesting !
After chemistry my second hobby is... caving and quarries. I cant say I ever thought of that. Most of the plumbing I've seen underground was either in mushroom farms or crazy people bringing water from one place to another to grow stalagtatites & stalagmites. Some bunkers I visited still had running water after 50 years: under a mountain, gathering moisture from the northern slope and collecting into a tank above the bunker.
Can you suggest any links or keywords so I can research this a bit more ?
@@herrhaber9076 I worked out in 1977 and presented at a meeting in 1978 that you can do total desalination of seawater with just the help of gravity, and no pumps at all... but when there is that much salt to be removed, a rather great depth is required, 11 km, like in the Challenger Deep of the Mariana Trench. There was some discussion of this on Halfbakery a few years ago, where many people were confused by the idea.
@@YodaWhat Thank you ! Wow, 11km is a lot. So... it's not really practical right ? I assumed this depends on the diameter of the pipe since a larger pipe would hold more water (therefore more pressure). Would this assumption be wrong ? I am not an engineer :)
@@herrhaber9076 Diameter of the pipe does not affect the basic principle, only the height is important for the yes/no question of "Will it self-operate?" Where pipe diameter would matter is the production rate, because a small pipe would have more flow resistance. Also, the pipe needs to withstand a crushing force from the outside, because throughout most of its height, the column of fresh water will be at somewhat lower pressure than the seawater outside the pipe.

Fanta Pee flavor! Great video, very informative!
Hope you enjoyed yourself in our silly little country in the North Sea!
I'd be more concerned with pharmaceuticals disolved into the river water.
the thames river is full of cocaine XD ... not joking
It's really good that you can go visit poor 3rd world countries like that with such bad sewage problems to investigate and demonstrate solutions.
this deserves more likes. The torries have taken 40 years to literally turn the UK back 200 years, but without any semblance of empire.
_burnnnnnnnnnn_ XD
next up: America X'D
@@puppypi9668 don't get me started. I AM american, and I saw the same things happening in the US for the last 40 years as well. It's all about the rise of the neoliberal "philosophy", which was never anything more than rich people rationalizing greed.
It's why I left the States after 5 generations and 45 years. finally bailed after W got re-elected the 2000s. no regrets since.
Ok the water filter with the bag he used it the bomb when I was homeless 2 years ago I bought one so I could have water even if I couldn't buy it stack 2 of them together for a super effective filter to filter urine
Great video, but I can't believe you didn't explore where the alcohol who went in the beer at the end!
the alcohol is a solvent, not a solute, so it would have gone into the jar with the water, and not the "beer concentrate".
New product - Alcholic water. (Rather watered down alcohol😝
Bear grylls would be so proud right now.
Love the memes
Your English is great, keep it up!!!,😀
I’d be reluctant to drink even the tap water in London - yuck! Living in Scotland, I’ve been spoiled by the lovely soft water up here. No scummy kettles either.
you really should have voted independence when it was offered. I suppose you still can though...
@@SharpElbows123 I would hope not! I haven't drunk London tap water since my youth (I was born in there) so maybe it's not as bad as I remember.
So very entertaining. Thanks
Thoisoi watches Cyberpunk 2077!
Interesting. Just the fact that it could be done is amazing.
Tere, Thoisoi!
I think you can recycle the polluted chemical and compound that sinks under the clean water and reuse the reagent again and again...
Amazing Horse by MrWeebl wasn't a disgusting lie?
+1 for horselicking.
The Thames is one of the cleanest rivers in the world
An interesting topic. I have a ZeroWater water filter from USA and it uses the resin and activated charcoal . I have been considering cutting the filters open (as I have several used now) and seeing if I can clean the components and reuse them . Is this possible?
In Nuclear power plants they use the same technology to get very pure water. To reuse the resin they have to do backflush with chemicals that will remove the built up impurities from the resin. It is not something that's worthwhile on a small scale.
Explanation:
It is jsut an industrial copy of the natural Moringa seeds powder, that is the origin of this effect. Look for out open source water filter and you will understand what we mean.
Best chemistry channel on RUclips! Much likes from Arizona!
I can make pee from lemonade very easily
I'm sure it's a translation problem, but what is "iron and aluminum sauce"?
lol can't say I've ever seen anyone do that.. but you don't buy beer.. you rent it....
6:47
The water was so pure Thoisoi2 began speaking the language of the Gods.
Strange, they say don't drink if water color is yellow.
actually, that usually just means it has some iron in it. not toxic.
3:37 I couldn’t tell what was being said here, turned captions on but didn’t help.
Is it “…act as inorganic coagulators..” ?
16:48 omg I thing this is the first time I have seen you speaking English into the camera and not a voiceover. It was *so weird* seeing your words lining up with your lips for once.
Btw Thoisoi you can DM me on Discord if you ever want to discuss YT stuff
Finally I can do something with my pee jar in my closet.
Ewwwwwww! 😹
Thoisoi do you compared the taste of the lemonade with the original product? 😉
XD
But seriously yeah, what did the sugar solution taste like before Science Lemonade XD
And what does Science Lemonade (Orange-ade?) taste like normally? XD
Controls are important! ^_^
Funny video
Thanks for making them.
I try not to miss any of them.
This guy is professional studio quality of content! He’s like the V-Sauce/NileRed of Eastern Europe:)
16:48 man this "lemonade" taste like piss, where'd you get it?
Lulz
You probably didn't pour enough of the powder, try 1 gram/500ml, it will taste like high quality water like when Mark Robert said it
What happens when you perform electrolysis on urine?
think: saltwater, but with yellow food coloring added.
You get hydrogen
Great video as always! Why don't you just speak English "live" all the time? Your voice sounds much better than dubbiing.
Hello sir any chemical or liquid that can glow bright light on darkness within 5to10 glow light this type of chemical or liquid available
1 million liters a day and that's raw sewage not just gray water that is insane
So basicly nothing new, just what we use in the waste water treatment like forever plus some biozide. The problem with clear drinking water isnt a technicale one, but a energitic one and a question of politic will/ money.
@future kidz: Pay attention to the greatest political scandal in 🇺🇲 history that's happening rn plz
#REALITY
Entertaining but you wouldn't like to accidentally mix up the bottles with the yellow liquids, would you?! 😆
Very cool. I would like to see you dehydrate something like coffee as you mentioned. Also I think that is the first time I have seen you speak english while on video and your english is pretty good.
Man I wonder if there's going to be a Collab between them...
Probably not, but it would be cool
@17:19 - Hold up a second...do you do your own voice-overs? If so and it's a known thing, sorry for sounding surprised. Is there any reason that you don't do your videos in English? I know I am probably going to sound dumb, but I never realized this.
His first language is Russian. They are a larger audience for him.
@@Burnt_Gerbil Thank you. I appreciate the information. I seriously apologize for not knowing. His English is impeccable.
When life gives you urine, make lemonade?
Life gives me lemonaide. Guess what I make🤣
Where's my beer? The eternal question. You're not just going to throw that pee out are you? So many possibilities.

From my understanding there hard to get because p&g donates all they make to third world countrys and all the ones u find are black market
It's good you know what you're doing.
I'd better not try this at home with my own "lemonde".
What happened to the title? It seems to be wrong
oh god I think I know where this is going... milk milk lemonade, round the corner fudge is made
I can't understand half of what this dude says sometimes
