ScienceMan.com provides free digital lessons and technology integration help for teachers and students. In this digital lesson, ScienceMan discusses and demonstrates the behavior of non-Newtonian fluids, and compares them with 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.
Mad respect I was straggling but your comment made it clear. anyway you still alive?
@@ibrahimalqurashi24 bro 😂
There are also a type of fluids which go against the gravity and come out from the container on their own. What type of fluids are they?
Plastic fluids are also called Bingham fluids!
@@abcdefgh6121 thats just zero viscosity (liquid helium i believe)
GOD! If somebody fell into a swimming pool of that, it would hurt a lot, then you would drown!
So funny!!!!!!!

No humans will only sink to their waist and then they will become buoyant.
AmazingGaming ahh. true my friend.
Mum: wtf are you doing? Me: *hammering bowls of fluids* Science!
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...
This is very interesting and amazingly explained, thanks for sharing
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.
I really like this. because I am learning ''non-Newtonian fluids'' at school
THIS WAS VERY HELPFUL! thank you for the visiual representation.
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
Really a nice explanation. I use this video to explain the concept to my students. Thank you!
thank you for the video. I needed that info for my homework!
This is really cool! I never knew there were actual terms to these kind of things.
Wow. So cool. Thanks ScienceMan!
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
Thank you very much!!!
Now I understand the concept of it, tyvm and nice video!

im a non newtonian fluid
thats clever, me too
Same bih, same
Hehe lol! You're good at replying
Bhay I am Oxygen
thx for dis my science project needed u
"Non newtonian fluid, son. They harden in response to physical trauma"
Thanks allot you helped me on my quimic homework
Wow. I didn't know this. Awesome 😎👍
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.
I am very glad it was helpful to you! 😃
"Why wont you die?" "Non-Newtonian fluids, son. They harden in response to physical trauma. You cant hurt me Jack!"
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.
Great idea!
Also, did it work??
Did it work? Film please
Where can i get one tho ?
Thank you so much!
I came to this video after a long dicussion with my family about if Edward Cullen is made of obleeck
there is research in progress as a fluid that can be used in bulletproofing applications.
oh it is very interesting topic.
"non-newtonion fluids son! they harden in response to physical trauma"
I LOVE HOW YOU MAKE THAT I REALY LOVE IT #ScienceMandotcom
thank you so much sir. i have a doubt regarding its property . is this material affect vibration also ..?
kzhead.info/sun/Zt6ohK-Qj4CHfI0/bejne.html You tell me
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?
That's a great question. I've tried that, and I regret not including that in the video (mostly for fear of making a mess). It's what you might expect... when you remove it very quickly, the mixture thickens around the hammer... if you can do it really quickly, it significantly raise the surface of the mixture and you can feel resistance on the hammer.
@@Science_Man ahh, that's what I thought might happen but I wasn't sure. Thanks!
Quicksand as well?
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?
hammer is me when solving the algebra
FRIT 3110 and H2O makes an AMAZING NN fluid!
So like oobleck?
Who is here from the Try Guys LMAO
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
This video was helpful in differentiating between N and NN fluids but where can I learn why NN behave as they do?
Here's the thing... no one is quite sure WHY NN fluids behave as they do. Research is ongoing, but it is a bit of a physics mystery. Here's an interesting recent article (bit.ly/28Ppo9L) explaining that progress is being made figuring out why NN fluids behave as they do.
So they could change their minds whenever they wanted, and we would never suspect? That's clever. We'll never know what hit us.
@@Science_Man I know. The cornstarch liquid particles still float around when applied force.
Corn starch instead of Corn flour or not?
You had me up until the ketchup..
this reminds me of the bubble shields from Star Wars
It hardens in response to physical trauma.
you can't hurt me jack
youre cool man !
Thanks
i'd like to see this effect in the armor jackets filled by these fluids.
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
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
+Lars Har Interesting question! But water is a Newtonian fluid, and behaves as such, no matter how fast you fall on it or how hard you hit it. The reason the water feels like concrete when falling at high speed is because you are carrying a lot of kinetic energy. That energy, when you strike the water, is rapidly transferred to your body's and the water's particles, with devastating results. Another way to think about this is, what if the WATER was travelling very fast? For example, a water jet. If water was a non-Newtonian fluid, it would harden to a solid when being placed under the immense pressure of a water jet - instead, it rockets out of the water jet at high speed, and with great kinetic energy. So much in fact, if you put your hand, or wood, or even metal in front of it, it would cut right through.
@@Science_Man oobleck isn’t that a non Newtonian fluid
Does it matter if it’s modified or unmodified corn starch? Theres a 5x price difference.
The cheapest cornstarch you can get will work fine.
So cornstarch is the father of the famous shock absorption liquid dO3
Can it be made into a bulletproof vest?
Probably not. It’s normally a liquid, so it would pool at the bottom of the vest.
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 ?
No
@@abdulmoiz5987 Why care to explain?
@@gertandriesduplooy7698 he never asked an explanation
@@abdulmoiz5987 I'm asking for an explanation.
The reason why it acts like a hard object is because I’m order to not die, Zoe need to slow down slowly, when you land on it at a great speed, you’re basically compressing the water, and as you probably know, water doesn’t like to do that.
Is quicksand also a non neutonian fluid ?
Yes! Quicksand is actually the opposite type of non-newtonian fluid compared to cornstarch. Quicksand is a "shear-thinning thixotropic" fluid, meaning that when force is applied, it becomes LESS dense. That's why thrashing around in quicksand will make you sink quicker.
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?
I dunno man but hope you found the answer
Oobleck is the stuff! We have a lot of fun putting it to the test on my channel.
Still a banger in 2023
Like a quicksand!!
What are some other dilatant non newtonian fluids that are more like oobleck than silly putty?
+SomeDudeOnline rub me and I'll show you dude
Yeah thnx
This was filmed in Canada.
Correct, eh! 🇨🇦
ScienceMandotcom yes
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...
I believe it's the Mistborn series that uses this as somewhat of a plot point. Or maybe it's some other book that I can't remember the title of.
If someone made a cornstarch helmet would it reduce the force of a punch done to the brain and by how much percent?
Yes, it would. By exactly 23.7 percent. The NFL should be using cornstarch helmets. 😃
This video is 10years ago wow
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
if you shoot a non newtonian fluid it shatters like porceline or glass. and then slowly return to its previous state
I’d like to see a test of a ballistic vest filled with liquid cornstarch. But I’m not wearing it 😅
I expect the Aether to be a non newtonian fluid. when resonant it waves transversly , when impulsed it waves longitudinal.
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 can't say much else than what I've already said in the video. Non-Newtonian fluids behave UNPREDICTABLY when different forces are applied. That's it.
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
Uhhh... I would consult your doctor.
It's harden in response to physical trauma. What did I just say? You can't hurt me Jack!
Good
It's like the shield technology from Dune 😅
How is is the glass bowl still there??
It’s not glass, it’s plastic 😃
Ah the explains it
Can it stop a bullet or a sniper bullet?
Depends on the depth and density of the cornstarch mixture, but one thing is for certain, it would take less cornstarch mixture than it would water, and it only takes a few feet of water to stop a high-powered rifle bullet kzhead.info/sun/p96mj92xo2NprKc/bejne.html
Wait what was that about ketchup?
Never did I think I'd yearn to hammer corn starch fluid yet here I am
Would a super mix of something like this work in bullet proof vest
+MrSt00000pid Good idea in theory, but in practice, the problem is that when you are wearing the vest, the fluid would settle - remember that without force on it, it flows just fine. So you'd have a vest with great protections around your lower waist, but everywhere else, you're in trouble!
+ScienceMandotcom what about if the bullet was made of this somehow? Possible?
+Mountaindew My prediction is that shooting a oobleck bullet would result in cloud of cornstarch powder from the muzzle of the gun. When a bullet moves forward, it's propelled by an explosive force. That force would turn the liquid oobleck to maximum density almost instantly. But oobleck at maximum density is simply solid cornstarch. Assuming whatever is holding the liquid oobleck in the bullet (for example, maybe it's thin plastic) disintegrates when the bullet is fired, then all that is moving forward is some cornstarch (followed by a bit of water that was also part of the oobleck, but let's also assume that would be vaporized to steam by the explosion). As the cornstarch leaves the gun, it is subjected to air resistance, and flies apart in a cloud (without the water, it is no longer oobleck).
Now I understand frog saliva! 🙌
Water becomes partially non newtonian when diving from high
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
I’m still looking for Joe!
I’m right here 😃
Psedu Liquids or Shear thickening fluids
Loadsa Elegance.
btw you can make non newtonian fluid with cornstarch and water :3
Salchicha Enlatada That's what cornstarch solution is, water is the universal solvent, and they gave us the solute, = solution. They did fail to mention the 2:1 ratio though.
Ah. Two to one. That was useful. Thanks.
So how much cornstarch would you need to add to 8 fluid ounces of water?
Sooo if we make a body armor with this..
That is what I was thinking
so that explains the quicksand
hey i watched this in fluids today
We can now walk in fluids...
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....
Also it's worth noting that if u were to actually shoot it with a 50 caliber bullet u would probably need a lot of oobleck so u can actually make observations
+Grant Bischoff It's a good question - first, it will definitely "break" in the sense that applying enough force to the newtonian fluid solidifies it, and if the force is great enough, it will fracture like any other solid. Stopping a bullet would actually require very little oobleck - perhaps only a couple of feet of it, since it provides more resistance than water, and it only takes a few feet of water to stop a bullet. I don't know about a 50cal bullet, but there is footage on YT of a .22 shooting oobleck: kzhead.info/sun/krihpLWjooqsl6c/bejne.html
So in theory could u make let's say a 10 foot wall of oobleck and have it stop anything, like a tank shot? (assuming that the oobleck would be held up and together by something)
Makes sense to me!
I can smell the corn starch from the screen
So can it crack?
Yes. If the NN fluid is like cornstarch and water, becoming more viscous with applied force, a particularly violent can cause the NN fluid to "break".
so does it break for like a couple seconds then become liquid again?
Who else has to watch this for homework??
lazy teacher? Or is this his channel?
Michael Verhoeven lazy teacher
Imma make this armor
This thing would be bullet proof, it hardens under the force of a bullet or tank shell/RPG
