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.
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
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.

Nice video, thanks!

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...
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
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.
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.
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.
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 ?
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.
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?
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.
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.
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.
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
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
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 ruclips.net/video/tzm_yyl13yo/видео.html
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
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?
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.
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...
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: ruclips.net/video/_ThtQkkXvdo/видео.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)
This is a good point. I wish I had used the word “suspension” instead of “solution”. I know cornstarch does not dissolve, so it’s unfortunate I mistakenly used the wrong term 🙁
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.

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?
