We can't actually feel wetness, we can only infer it. amirite?

Moisture is the essence of wetness, and wetness is the essence of beauty.

I swear to God, a kid asked a question like this (how does the brain feel wetness) in freshman science class, after the teacher literally dared us to ask him anything to try and stump him, and the teacher totally shamed him for asking a stupid question "because you just feel it."

Ugh bad teachers are the worst influences in the world
by Anonymous1 year ago
but the good ones are some of the best. I still drop in and say hi to some of my previous high school teachers from time to time. I feel like I really lucked out in that regard because the majority of mine were in the "good" category.

I got a mixed bag but i definitely remember the good ones more than the bad ones

We were learning about properties in science. This teacher had a coffee cup and was talking about how the air around it was a gas, the cup was a solid and the coffee was a liquid because it takes the shape of what it is in. Then, he flipped over his cup, and dumped his coffee out and said see!
This same teacher was saying how you can't see heat. I asked him why on a hot day you can see the waves of heat coming off the pavement. He just stared at me for like a minute. And then completely ignored the question and moved on.
He also moved his tongue all over his teeth while his mouth was closed a lot. I think he was on something.

I hope you got your answer but in case you haven't, it's hot air rising at different rates causing light to refract slightly different at points in that area. And since the heat dissipation is ever changing the refraction differences undulate throughout the affected area. Pretty cool.
by Anonymous1 year ago
It's the difference in density, more specifically. A stable candle flame can produce a similar effect, but without all the motion you're used to seeing on a hot day, for example.
by Anonymous1 year ago
Yeah exactly. The differences in density cause the change in the refractive index and it's like a mosaic of differences that keep changing over asphalt.

>This same teacher was saying how you can't see heat.
Well, actually you can't. You can see the effects, e.g. air refracting light due to heat.

our physics teacher was bald and let us practice calculations by dropping eggs on his head as he walked by underneath the bleachers. He also let us shoot off rockets behind the school. cool dude

kid: Good explanation, thanks, now I understand why I feel like you're a bad teacher.
by Anonymous1 year ago
He isn't wrong though.
"Feel" is temperature and pressure and your body is familiar with the changes to them that occur with water or wetness.
This means that you brain can be easily tricked when pressure and temperature mimic wetness without actually being wet.
A hand in a nitrile glove under running water does not get wet but feels wet due to the pressure and dropping temperature.
Some animals do have Hydrodynamic sensors and they can detect water movement but humans assume wetness through touch.
by Anonymous1 year ago
If you've ever touched running water with nitrile gloves on, you'll know it's trippy, your brain says your hand should be wet but it's completely dry, solely because the temperature change and texture is there

I hate the feeling of cold water on my hands so I use dish gloves when washing dishes. We didn't have any one time and I used nitrile gloves instead - they were useless
by Anonymous1 year ago
Do you wash dishes with cold water?
by Anonymous1 year ago
I will rinse with cold water if im not using the dishwasher for some reason, do you not rinse off the soapy water?
by Anonymous1 year ago
Rinse, okay. Personally, I still use hot or at least warm rather than cold to rinse. But I wouldn't *wash* my dishes with cold water
by Anonymous1 year ago
Hot water is definitely still better than cold water. It seems to be "wetter" and grabs dirt and soap/foam better. It's a trade off of heat energy or using more potable water and time, it feels like.
by Anonymous1 year ago
In case someone reading this wonders why this may be: The surface tension of water changes with temperature, becoming lower as the water heats up. This lower tension is why the water seems "wetter", and makes suds easier when lathering with soap.

You can put your hand into bodywarm water, without noticing that your hand is underwater
by Anonymous1 year ago
this is on the level of "we dont actually see things as they are, we just infer it"
by Anonymous1 year ago
I never understood this. Who are you to determine which level of "feeling" this belongs to. In my book, if you're determining the texture and temperature - you're very much feeling it.
by Anonymous1 year ago
Yeah this is getting philosophical.
by Anonymous1 year ago
IMO this is the difference between feeling and inferring. We can feel changes related to texture, pressure, osmolarity and temperature. But we need to infer changes related to wetness (thermal and mechanic receptors) and UV radiation (sunburns). This is different from other animals, fruitflies can directly perceive wetness and the bees can see UV radiation - i.e. they have specific organs/cells to get this information.

OP if what you say is true then help me out. I teach twenty 2nd graders that I have to teach science.
Tell me how I set up something that feels wet, that isn't wet.

As an amateur plumber - checking for leaks by hand feel is nearly impossible. I have to use a gray t shirt or something that will visually show moisture.
by Anonymous1 year ago
Yep. Try it out even easier. Put your hand into the water while wearing latex gloves. You will feel habd and fingers getting wet but in fact they are just cold.
by Anonymous1 year ago
When I was working in the lab and put my hands under running water while wearing gloves, I would feel like my hands were wet. But when I took them off my hands hadn't touched water at all. It was just my brain making an inference based on temperature and probably a few more things.
by Anonymous1 year ago
You are correct that the sensation of "wetness" is not directly caused by the presence of moisture on the skin. Instead, our perception of wetness is inferred from other cues such as changes in temperature and texture. The skin does not have specialized receptors, called hygroreceptors, for detecting moisture.
