Inventor: I just invented a machine to wash your clothes!
Friend: Awesome! How does it work?
Inventor: No f***ing clue m8
It does the spin thing similar to how we wash it ourselves
Probably me if I invent something. I just like to create something but I don't know how it work.
Minecraft Redstone is one of the example I just don't know how it work a month after I finish the project.
In the immortal words of Todd Howard: "It just works".

SLS is also in most toothpastes causing them to foam up, and it also binds with your sweet taste receptors on your tongue, blocking them from allowing you to taste for a short while, which is why orange juice tastes bad after brushing.

It’s not that hard to exploit a phenomenon. We still don’t fully understand how friction or airplanes wings work, but we use them all the time with great skill. All we need to know is what conditions cause the phenomenon, and then a lot of testing.
Most medications for example. We know that drug works, but we usually don't exactly understand how.

Yet they still can't figure out why my Deodorant makes the pits a rock solid mass from Hell after I wash them.
Your detergent of choice and deodorant chosen. Odds are the two act oddly chemically when mixed.
You actually finally explained to me why a stuffed washer is not a good thing, leaving clothes feeling and smelling half-washed. Given that they don't have enough room for the clean water reaction you mentioned, it now makes perfect sense.
Exactly an overloaded machine also puts a lot of stress on the drum bearings
It amazing that we are still learning things about things as mundane as laundry.
Cardinal rule of washing: "The rinse is more important than the wash."
I've been practicing (and occasionally teaching) how to clean things: surfaces, clothes, kitchenware, and food. I'm totally unqualified, other than that I experienced a pesticide poisoning in 1980 and was taught some cleaning techniques to remove chemicals from my environment due to the resulting chemical sensitivity. This did however give me the impetus to further investigate cleaning methods. When I wash my clothes, I run them through an entire second wash; your video helps explain why my clothes end up so clean and with that fresh air smell!
At the end of this vid, you mention your big concern is that the clothes smell fresh. Let's investigate that for a moment:
What creates smell? Molecules in the air are breathed in and pass by the olfactory (smell) bulb deep in the nose. These molecules interact with chemicals in the bulb, resulting in stimulation of nerves--you get the idea. The key component of this is the idea of molecules in the air. In the case of clothes, where do these molecules come from? If there is anything on the clothes that can evaporate and subsequently trigger a smell perception, then this means there has to be something on the clothes for it to evaporate. Most laundry products, including detergents, softeners, anti-static sheets, and even some bleaches have fragrance added. Some so-called fragrance-free products even have what is called a "masking fragrance"; check the ingredients! If your washed clothes has that "fresh air smell," what you are smelling is a residue left on your clothes after the washing. In other words, your clothes are not actually fully cleaned! Properly cleaned clothes have no odor, with a few notable exceptions: natural cotton fibres will outgas (place molecules in the air from a surface) some of the residual oils inherent in the cotton plant; synthetics such as nylon and polyester may outgas some of the chemical residues left over from the manufacturing process. A sensitive nose may be able to smell these; they mostly have, especially in the case of cotton, a non-offensive odor, and for some, especially in the case of cotton, may actually be considered a pleasant "fresh air smell."
Carefully choosing laundry products with little or no fragrance is another step in ensuring that your clothes are properly cleaned and potentially have a true fresh air smell after their visit to the washing machine.
Thank you

Ryan Nguyen Then again, Ovens caused an ultraviolet Catastrophe
I bet we still don't know how electricity truly powers our machines. I mean, sure, you can describe what it does down to the subatomic level but how it does it? No chance!
It's possible to know, through testing, that something works without knowing how it work. Knowing *that* something works only requires data. Knowing *how* something work requires theory.
Engineering doesn't always wait for science.
Dominic H. What do you mean? That doesn’t make any sense. I mean, from a philosophical perspective, we could argue that we know absolutely nothing about the world, but from a scientific perspective it’s very clear how electricity works thanks to Maxwell and company.
So, increase the rinse water's electric field strength AND faster rinsing speeds.
No
@@quantumsigmaqed6312 What do you mean "no"?
Meh...we don't wash our clothes with heavy water.
That's so funny. I double rinse my clothes sometimes because I think it makes them cleaner. I figured it got more of the detergent out.
As a former laundry engineer I appreciate the explanations in this video. Much appreciated!
This episode just made me relive the time my first college boyfriend informed me that he had been doing all of his laundry for the past 2 years without any detergent at all because he "didn't realize he needed it". That honestly should have been more of a red flag than it was at the time...
I'm not sure what I found funnier, the fact that he wasn't using laundry soap for 2 years or that he didn't know he needed to. Its called laundry soap right? Its function seems obvious from its name ... unless he didn't know what the word soap means?

@3:10 Theword "Colloidal" is pronounced such that is sounds like "Collide- al". I believe that middle syllable is normally pronounced "oi" similar to void, droid and roid.

I got a washing mashine ad on this video
Inventor : let's build a cloth washing machine
No body : how'd that wash clothes ?
Inventor: let's just build it, we'll figure that out any other day.
This is actually a very important finding. Basically you can save up on detergent and water just by soaking clothes in a more saturated soap solution by using less water. Then just expending the energy and water usage for the rinse cycles.
I applied this new discovery to washing my car and found that rinsing it after i washed it makes it so much cleaner. I must be a genius. My mother would be so proud.
Scishow: beware of clickbait
Scishow: WE JUST LEARNED HOW WASHING CLEANERS WORK!?!
When they just called Washing Machines 'womans friend'
That was when men were all filthy beasts who didn't know how to wash anything.
It was better than beating the clothes on rocks.
@Reece A Do you have a better explanation for why it was called "Woman's Friend" other than the sexism rampant at the time?

You should not have revealed these secrets. Now plushie “friends” can figure out how to stay dirty forever.
This is like the best SciShow episode ever.
This has been bothering me for a while now...
Every sentence said by Olivia always ends in a crackle in the last word...
When you notice it, you can't unnotice it.
After knowing this for a while now, I'm always a little bit irritated after watching an episode with Olivia in it.
You're welcome.
Ig I hear it doesnt bother me tho. Kinda like an accent ig I just like it eh idk.
What's "Sodium Yanny Sulfate?"
It helps wash the blue out of your golden dresses ;)
@@laochraelle800 Touché.
When she said "sodium lauryl sulfate" at 3:44 I heard Yany...
This seemed like a really odd post when I first saw it. Basically, I was trying to figure out how something could exist for a century or more, and nobody understood how it worked. After watching the video, I understand, but it still seems strange that nobody ever worked out the physics of it till now. Makes you wonder how many other things we use every day are also a mystery to science.
50 years ago my mother taught me the rinse cycle was more important than the wash. Use a small amount of soap unless the clothes are greasy, then rinse with copious amounts of clear water; even rinse twice sometimes.

this is exactly why I love science soooo so much.
Me: I'm immune to clickbait
Also me:
So many modern washers only have cold water rinse.
..if it has hot water rinse...it would be better?
Why does drying on cloth line form lots of wrinkles; while cloth from dryers have much fewer wrinkles?
(Do people today even know what a “cloth line” is???)
Hold on, did you say "Sodium Yanny Sulphate"?
0:33 - "WOMANS FRIEND"
I wonder if this would work today...
Imagine washing clothes PRE washing machine
@@speedy01247 Did that for 2 years as there were no washing machines where I lived.

Machine probably would work, "women's friend" not that much.
I couldn't find any Soduim Yanny Sulfate in my detergent, weird
Underrated comment
Could you do a video on topics like this, that seem so fricken simple, and are so commonplace, but are unsolved? These kind of things are really unheard of before they get solved, I think it would be cool because someone watching your video could solve an unsolved problem they otherwise most likely would never know about.
TIL something I never knew that was quite interesting but will never need to know again. Thanks SciShow.
POV : your in the laundry mat looking at the machine wondering how it works and now your here
Fascinating,... and makes a lot of sense. Serendipitously, I noticed that soaking my clothes for a long time in the rinse cycle seemed to get them cleaner...so I do this all the time.
True, if you replace “scientists” with “my dad.”
This is so fascinating! It's what I guessed when you began talking about it but it's really cool to hear about the details!
Are washing machines where dark matter comes from?
My God!
THAT's where all those missing socks go!
*2018:* We are on the verge of an AI breakthrough that will lead to the next industrial revolution, the era of post-scarcity, the terraformation and human colonization of mars, and the realization of the Singularity!’
*Also 2018:* ‘Scientists were finally able to figure out how washing machines work.’
As someone who delivers and installs washing machines, I actually appreciate this video. Now if you can do one for ‘steam drying’ I could then explain it to our clients.
likely like washing hands need to wet first then soap then rinse. but 4 washers one might be able to do : clean water, agitate, soap, agitate, drain , clean water agitate, drain, spin, drain.

@@chaosisblond right? Aniotic? 😂
I wish they would do a special scientific segment on how to properly use laundry detergent especially for HE machines because MOST people use way too much laundry soap in one load then blame the machine for poor performance and rinsing.. Like if it says fill to line 1 for HE machines don't fill it to line 3 anyways then turn around and complain HE machines are horrible at cleaning.. I was once one of those people until the day I experimented and "ACTUALLY" followed the directions on my laundry detergent of choice and realized my machine wasn't the problem but instead my ability to simply follow instructions when they put those there for a reason.. Alot of people hate the new fancy HE machines because they don't use them correctly and treat them as the old school washers we ALL grew up on and with those less is more.. More soap will not clean your clothes better in one of those infact it has the opposite effect 9 times out of 10. Every washing machine review I've watched on youtube whether it be an HE or Old School everyone uses waaay too much detergent like its ingrained in our culture to use a WHOLE full cap when most of the time is not necessary.
Yet another awesome video about something so mundane. Keep it up
I work in an industrial clean room where we have to clean our product very precisely. Too little surfactant and the clean process has to be repeated (wasted time and resources), too much and it is possible to cause expensive damage to the product.
The concentration testing of surfactant in water is tested electrically by simple electrical resistivity.
And it occurs to me: a home washing machine could do the same thing automatically. It would have a supply of detergent that it could meter out slowly.
First, the resistivity of clean incoming water would have to be established.
Second, the resistivity of water flowing over the dirty clothes.
Third, as detergent is added to the agitating clothes the micelle action starts. Initially, before surfactant micelles attach to "dirt" the perceived concentration in the dirty wash water will be high. As more surfactant finds dirt the measured concentration will drop.
Fourth, repeat slowly adding small amounts detergent until there is no change in resistivity of the wash water. This should be when detergent is no longer needed.
It might be possible to do this in reverse for the rinse cycle to reduce rinse water used.
Also: this should DEFINITELY be done with the water softeners that may not be needed at all where you live but detergent manufacturers add to all detergents.
Diffusiophoresis sounds like a magical spell from Harry Potter
Two things:
1) your animation was done wrong. it doesn't show what you're saying happens.
2) anyone who's hand washed their clothes knew this, because you can see it happen.
More like Sodium Yanny Sulfate!

If you ever washed your clothes by hand on a flat Rock bed, friction speed and water movement is essential in getting stains and dirt off.
It's kind of like scientists figuring out how alcoholic spirits are really made.
Seriously have they?
There are times i feel a slight jolt while dipping my hand in a soapy mixture. Is it the anionic charge?
I with no degree figured this out by myself years ago. in layman's terms of course but still that's exactly how I thought it worked what the hell have these "scientists" been doing this whole time?
Now I know why I set my machine for extra rinse.
Well now I’ll always press the extra rinse button on my washer
Machines don't even have that kind of mode
Modern machines don't even require it as the water is more than enough to rinse the laundry.
@@stephensnell5707 idk what you’re talking about because many washers let you select extra rinses.

@@humanrightsadvocate Better than being a douche for no reason.
Got an upright "eco-friendly" washer when they first came out 10+ years ago & it did not work properly. Made my clothes even stinkier coming out than before they went in. Now I know why my brand new "old fashioned" washer that opens on top works better... it's not the agitator like I was thinking, but the rinse cycle runs longer actually cleaning the clothes! The upright was definitely not eco-friendly because I was having to wash for 2 sometimes 3 cycles ugh!
You need to use a Front Loading machine as those get clothes 100% clean with no odours remaining at all
Lol I was JUST thinking yesterday about how wonderful washing machines are, relative to the alternative.
For over a decade we’ve used an ozone generator that infuses ozone into the wash in place of detergent. It’s worked really well, would like to hear your comments/research on this method 🙂.
I just had a conversation about this a few weeks ago. Creepy.
Nice video, but the explanation on how micelles work was a little confusing, if not wrong. In reality, the hydrophobic part (the tail) bonds with the fatty plasma membrane of bacteria and dirt particles. The hydrophilic part (the head) then gets dragged by the water to move the micelle away from the pants, consequently moving the dirt away too. That’s a general idea, and not counting all the other things that are happening in the mean time. Nanosystems are awesome!
This went from “honey how does this work” to “but let me tell you How you’re getting my skid marks out” way too fast
So scientists worked out rising out soap with clean water is better than using soapy water..... Okay then.
Well, I’m now at peace with the fact that these things actually do clean and not just spin my clothes in circles for 30 minutes
As a former Industrial Laundry pioneer. I can say that there are so many variables not being taken into account.
An industrial Laundry washer (Tunnel) does not spin, it just turns from left to right and as it transfers it spins once in order to transfer the load into the following module. Quemical conscentration, temperature, mechanical friction among other things are needed to fully sanitize.
The only thing holding back the laundry industry is the bleach, it just cant sanitize anything in less than 2 minutes and 40 seconds. Our Tunnels just cant transfer anything faster than that. Many Laundry leaders dont know this and dont even bother to do the proper research and completely ignore this, then they are wondering why they are getting astronomical amount of stain out of the production.
Conclusion, there is more to laundry than just chemistry.
I love how she explains things. People that care about their content are the best. Much love girl youre my fav!!

19th century sexism strikes again.
I offer a apprenticeship for a scientist to wash my clothes - it comes with the usual conditions for scientific work like no payment, no budget and senseless documentation but a catchy phrase for your CV to impress clueless people who can actually give you a job that pay off you loans at your 70th birthday - if you are one of the lucky ones - by hard and humiliating work and selling your soul.
If you are a smart guy who made all the right decisions in your life we welcome you to our team!
Who ever done this research must be had lots of free time and very bored! 😅😅😅
Well, it's always been known that they work pretty much the same way as hand washing clothing. So the "mystery" isn't what the title might suggest.
