ScienceMan Digital Lesson - Physics - Non-Newtonian Fluids 

Something that wasn't mentioned was how Non-Newtonian fluids are broken down further into 3 different classes, Plastic, Psuedoplastic, and Dilatant. Plastic and psuedoplastic fluids are also called shear thinning, because the more force, or shear, is applied, the more fluid they become. However, plastic fluids need a certain amount of force to be applied before they'll start to move. Psuedoplastic fluids will move as soon as force is applied. Ketchup is a plastic fluid. Paint is psuedoplastic.

The ancient yet amazing Silly Putty (boric acid plus silicone oil) is a fascinating. It was invented by James Wright in 1943 at General Electric. It's properties fascinated me since I was a kid, but the non-Newtonian fluid concept was known by me until I've read an article on SciAm by Dr. Jearl Walker when I was studying physics in late 80s. Nice video, thanks!

GOD! If somebody fell into a swimming pool of that, it would hurt a lot, then you would drown!

Mum: wtf are you doing? Me: *hammering bowls of fluids* Science!

Came here from Space article that described the black liquid in Prometheus and Romulus as Non-Newtonion fluid. The cornstarch+water mixture is SOO CRAZY!! I'm MIND-BLOWN. 4:39am 6.9.2024

Thanks for the great video! I have tried this DIY of non-Newtonian fluid before and as I poured excess water, it failed and become something just like normal liquids.... Remember don't add too much water...

I really like this. because I am learning ''non-Newtonian fluids'' at school

Dilatant is what is called shear thickening because it becomes less fluid, or more viscous, when more force is applied. The corn starch solution mentioned in the video is a good example of this.

Shampoo is speciafically designed to be viscous unless you shear it with your hands, so it doesn't run off your hands, but spreads nicely when you shear it while applying to your hair

im a non newtonian fluid

This is very interesting and amazingly explained, thanks for sharing

Man this would be borderline magic for me as a kid if they showed it in school but no all they do is let you smell some sulphur

2:22 _"The slow blade penetrates the shield."_

Okay, I understood all of that. Now, what happens when you put the hammer in gently and try to rip it out really quickly? Does it have the same effect?

THIS WAS VERY HELPFUL! thank you for the visiual representation.

I just got this idea to help fix my car dents. Since I can't get an anvil in back of my fender, maybe I can get a bag of this fluid behind it. Then I can bang the dent smooth. I think I'll go to a junk yard and experiment on a car that doesn't matter.

Awesome Fascinating 😊

hammer is me when solving the algebra

I've been using the comparison between non newtonian fluids and my ADHD brain for years. This video helped illustrate that to some people I was trying to explain it to.

You had me up until the ketchup..

This is really cool! I never knew there were actual terms to these kind of things.

When something falls to water from enough height water also behaves like a solid object because of surface tension.So if we apply enough force,water also changes it's viscosity.Doesn't it makes water a non newtonial fluid ?

"Why wont you die?" "Non-Newtonian fluids, son. They harden in response to physical trauma. You cant hurt me Jack!"

Now I understand the concept of it, tyvm and nice video!

Thank you very much!!!

Really a nice explanation. I use this video to explain the concept to my students. Thank you!

Wow. So cool. Thanks ScienceMan!

I came to this video after a long dicussion with my family about if Edward Cullen is made of obleeck

oh it is very interesting topic.

Wow. I didn't know this. Awesome 😎👍

Who is here from the Try Guys LMAO

thank you for the video. I needed that info for my homework!

there is research in progress as a fluid that can be used in bulletproofing applications.

"non-newtonion fluids son! they harden in response to physical trauma"

So, why Non-Newtonian ? 3rd Newton law tells that an object applies the same amount of force to another object which applies force on it. Here these fluids apply the same kind of force to the object, for example starch applies the same amount of force (impulse more exactly) on the fast hammer so it bounces back but the slow hammer submerges, on the contrary they should be called true Newtonian fluids!

I like how you buy the products with no brand.

It hardens in response to physical trauma.

Quicksand as well?

This video was helpful in differentiating between N and NN fluids but where can I learn why NN behave as they do?

Does it matter if it’s modified or unmodified corn starch? Theres a 5x price difference.

Wow this is y i love science

Hi , So if you fall from a helicopter 500 meters above the sea in the see and a moment before your fall you shoot in the water a bullet will that safe you from the hitting and would you survive?

y does that hammer on the cornstarch solution satisfying?

Very interesting, but why is the video like 15 fps?

Its so crazy its not giving any room for striking objects but it's letting them sink in slowly! Possibly good for body armor. I wonder if it can deflect something like a bullet... Only one way to find out. P.s. it looks like the android fluid in Alien series. 4:55am 6.9.2024

thx for dis my science project needed u

thank you so much sir. i have a doubt regarding its property . is this material affect vibration also ..?

This was filmed in Canada.

So like oobleck?

I've heard that hitting water at a high velocity is akin to falling onto concrete. “I know it’s water down there, but it might as well be concrete. You’ll be flat as a pancake the second you hit.” - The Eye of Minds by James Dashner. I have heard it in other places too and referenced it to a Mythbusters episode of walking on corn starch. So I started wondering, since corn starch appears to change viscosity as a non newtonian fluid mainly when struck with force quickly rather than when the hammer is slowly submerged with force. Then surely, according to the quote above, water is a non newtonian fluid only if it is struck at a very high speed with force. I'm writing a fanfic for the novel and am at the first chapter (only story on the series so far) so I would love to find out so I can add in one awesome sentence about physics into the story. www.fanfiction.net/s/11849314/1/The-Eye-of-Better-Alternity Thanks

So cornstarch is the father of the famous shock absorption liquid dO3

I LOVE HOW YOU MAKE THAT I REALY LOVE IT #ScienceMandotcom

What are some other dilatant non newtonian fluids that are more like oobleck than silly putty?

I have a great idea for this actually. But I am just a kid so I can't do anything. But this could be used to save lives

what type of glass doesnt break after getting powerful drops from a hammer

Thank you so much!

Thanks allot you helped me on my quimic homework

some wet sand at the beach is like this it barely acts like a fluid though quick sand is the classic example that's what makes it so hard to escape

Hey! I have a problem with one question and that is which Newtonian fluid of everyday use has such a complicated viscosity that we use a fourth order tensor to describe it? Can someone help me, pls?

FRIT 3110 and H2O makes an AMAZING NN fluid!

Imagine being trapped in the cornstarch solution practically sinking down into the solution all the way to the point that the solution is above your neck... i had a nightmare like that...

Is quicksand also a non neutonian fluid ?

if water and honey are Newtonian - then why do bullets bounce off of it? I was shooting at the honey jars the other day, totally bounced

if you shoot a non newtonian fluid it shatters like porceline or glass. and then slowly return to its previous state

Where can i get one tho ?

It can be used in boxing gloves and no one will ever know. If you punch it will be hard like a rock and if someone checks your gloves by applying pressure it will be soft as liquid

Still a banger in 2023

If someone made a cornstarch helmet would it reduce the force of a punch done to the brain and by how much percent?

Very nice

Corn starch instead of Corn flour or not?

How is is the glass bowl still there??

Can it be made into a bulletproof vest?

"Non newtonian fluid, son. They harden in response to physical trauma"

I’d like to see a test of a ballistic vest filled with liquid cornstarch. But I’m not wearing it 😅

Sooo if we make a body armor with this..

Hello, I just watched your video Because I have been trying to lose weight but I’ve been eating corn starch for about 10 years now I haven’t ate it for about a year but I feel like it could be stuck and I have a Lotta reasons why I feel that way do you have any suggestions for me just in case I do have corn starch stuck inside of my body I know it sounds crazy but please let me know

Never did I think I'd yearn to hammer corn starch fluid yet here I am

We can now walk in fluids...

Okay. So why is Google saying that cornstarch isn't soluble in water

this reminds me of the bubble shields from Star Wars

Hey science man, is there ever a point where the non newtonian fluid will break? I mean sure it withstand a sledge hammer but will it withstand a 50 caliber bullet shot out of a barret....

Like a quicksand!!

Can it stop a bullet or a sniper bullet?

Water becomes partially non newtonian when diving from high

How to explain to my mum if she enter in room and see me hiting Olive oil with hammer

So can it crack?

It's like the shield technology from Dune 😅

Now I understand frog saliva! 🙌

Wait what was that about ketchup?

I’m still looking for Joe!

Thanks

i'd like to see this effect in the armor jackets filled by these fluids.

youre cool man !

I expect the Aether to be a non newtonian fluid. when resonant it waves transversly , when impulsed it waves longitudinal.

Psedu Liquids or Shear thickening fluids

This video is 10years ago wow

Oobleck is the stuff! We have a lot of fun putting it to the test on my channel.

Yeah thnx

so that explains the quicksand
