This is pretty neat. A easy at-home way to see this is to find the right mix of cornstarch and water. Put a little in your hand, it should feel a little thicker than water. When you squeeze it with your fingers, it hardens. Pretty cool!
i believe its the same reason you can run on cornstarch and water, its a non-neutonian liguid, meaning when force is applied to it to molecules in the cornstrach stack together like blocks are are soild for and instant, this video shows it on an amplifier which applied a constant force which alowed the corstarch to stay at a relatively soild state the whole time
actually, if you want to try this at home, mix cornstarch with water then hold it in your hands, push your fingers slowly through and it's a liquid but if you crush it as hard and as fast as you can it turns into a solid. the farady waves are turning the mixture into a semi solid state.
it's just a suspension of cornstarch and water, that (as long as suspended) is non-newtonian. paint behaves in the same way, but reversed. when pressure is applied, the cornstarch suspension thickens, but paint thins.
Great! Seen experiments where people actually walked across the surface of cornstarch solution. If you apply enough pressure,it becomes solid. Amazing indeed!
What I understand, which isn't much, from the wikipedia article is that if it was "newtonian" you could describe the viscosity of the liquid accurately, but because of the nature of non-newtonian liquid, it has unique behavior (especially with the vibrations) that make describing the viscosity difficult (I guess Newtonian physics goes into viscosity or something like that)
this is a similar principle with what their doing with newer kevlar vests. a liquid behind kevlar that when struck by high velocity object hardens immediately.
What you see here is an example of a so called Non-Newtonian fluid. It behaves like fluid when nearly no force is applied. But when you apply a force it behaves more like a solid matter, because it consists mostly of particles with a high friction coefficient against each other but which are surrounded by a thin layer of water between each other. The sonic waves apply frequent forces and become indirekt visible in the case of a resonance.
Next thing you know, the cornstarch develops intelligence, learns to control its own vibrations, kranks it up to 100,000 g's, sprouts flame-throwing knife swords, terrorizes the town, and is ultimately thwarted by Bruce Willis as John McClane. Seen it, man.
If they could motion capture that last "writhing finger" movement and blow it up to say, ten feet tall, It would make one heck of a movie special effect. Like some monster of the underworld bursting out of the ground.
I think you are almost right. I think there has to be a connection. more like the noisiness of the quantum levels. or even the fabric of time and space at quantum level
TIP: if you don't have that rotating plate, you can do what I have done. use your sub-woofer (to whoever has a stereo system) It works the same as that when the bas is high, its even easier to set as you want...
it has to do with the wave frequency that is being sent through the object, like hold on to a rope that's waving, but instead of you holding onto it and it stopping it keeps waving despite the fact that your holding it, its all about getting the right frequency
not fake, they did this on mythbusters at one point, and you can easily make a corn starch solution like this at home... it flows like a thick liquid when it's under no physical pressure but if you try to squeeze it it will solidify as long as you maintain that pressure.
that is a non-Newtonian fluid. some of my classmates made a batch and were able to stir it, and it flowed like a liquid, but were able to run across it without sinking in
If you have a loudspeaker that can go down to 120Hz then you can do that, a subwoofer would definitely do it. Try it with different waveforms, or with multifrequency tones.
You can do the same thing with a cornstarch and water mixture. It's not fake. I think that the liquid in this video is a cornstarch and water mix because it acts very very much like one.
Thank you Brianso8, I loved the Faraday action! I taught my kids to play with this mixture, and about how some of the properties of friction work, in a piece of tupperware filled with this mixture.When they poked their finger in rapidly, the mixture offered fairly strong resistance, but if you slowly put same finger in, it glides in easily. Same with trying to yank your finger out quickly, versus slowly. Sort of a mini version of quicksand. ^_^
Fascinating stuff. This material is basically very fine mud... I'm wondering about the practical applications wrt earthquakes, where we see the opposite effect, ie. the earth's shaking causes seemingly solid ground to behave like a liquid.
Haha... I seen this one.... it is how liquid react to a sound and vibration in a certain frequencies... it is amazing to see how that liquid combination create such a reaction... imagine we can create an object with this method and quickly harden the object...
WORD TO THE AUTHOR: It would be nice to put some details about the physics of the phenomenon in the description of the video. It would take much more than 500 characters to explain it but I will try posting a brief summary soon. In the mean time one can Google some keywords. This is called a "shear thickening fluid". One very nice application is what we call a liquid armor...
If you can't find a vibrator (lol, not that kind) for this kind of thing, perhaps you could make one with a slightly off-center weight and something that spins in which you can control the spinning speed, like a high quality motor.
Eh, no. It's not a plasma, cinematic, or a tear in any dimension. It's called a Non-Newtonian Fluid, which basically means it doesn't obey Newton's laws of viscosity. When pressure is applied the atoms of the substance get closer and lose energy, when at rest, or acted upon lightly the atoms remain as a similar distance and frequency to a liquid. BTW I'm 16 and i know this...
if anyone whats to do this mix flower(corn starch) with water until you get a slightly thick liquid but still flows normally the get a speaker that doesn't have a cover on it lay glad wrap over the speaker so the liquid doesn't wreck the speaker and pump the music and watch the magic
I tried that with my usb massager, it was so freaky... put a few drops of the cornstarch+water mixture on it while it's vibrating and they did seem to come alive!
Very fine example of bending time and space with frequencies... Hhmm... Interesting. It's obvious that gravitational behavior against the substance is being altered. Think of the possibilities. Nice.
@salirezakm A loudspeaker. Mix cornstarch with water, put it on a plastic film on top of a loudspeaker, hook it up to a tone generator, that is really all it takes. It's cool stuff.
Not computer generated at all. When I was a kid I used to play with this all the time. Never did use a faraday wave- but no doubt in my mind it does what he says. So cheap to make- hours of fun and experiments
Is this what we in the UK call Cornflour, white stuff you use to thicken sauces? I discovered you can pick it up, if you keep it moving - like rubbing a ball between your fingers, as soon as you stop, it turns liquid and drips away again. As a kid, I used to make such a ball, then hand it to someone! heh heh heh. I wondered if it would make a good Gearing clutch? Neat video though.
This is pretty neat. A easy at-home way to see this is to find the right mix of cornstarch and water. Put a little in your hand, it should feel a little thicker than water. When you squeeze it with your fingers, it hardens. Pretty cool!
1:58 now... that amazing, what an great effect the cornstarch makes.

You can see the phase change, from liquid to solid. It's beautiful, not scary.

it's just a suspension of cornstarch and water, that (as long as suspended) is non-newtonian. paint behaves in the same way, but reversed. when pressure is applied, the cornstarch suspension thickens, but paint thins.
damn the ending is so cool!!! its a newtonian solid which means its a liquid but the molecules bond together when pressure is applied
Great! Seen experiments where people actually walked across the surface of cornstarch solution. If you apply enough pressure,it becomes solid. Amazing indeed!
What I understand, which isn't much, from the wikipedia article is that if it was "newtonian" you could describe the viscosity of the liquid accurately, but because of the nature of non-newtonian liquid, it has unique behavior (especially with the vibrations) that make describing the viscosity difficult (I guess Newtonian physics goes into viscosity or something like that)
it's true. with pressure it changes fluctuates between liquid and solid
you can roll it up into a ball, and when you stop rolling it, it will appear to turn to liquid. applying pressure makes it solid
different pattern and degree of strength of minute vibrations made those crazy patterns of waves of cornstarch put on water
we called it oobleck in 5th grade! You poke at it and it's hard, but it still flows out. Neat stuff.
YES ! I was just thinking about filming some cornstarch and water the other day. how funny to stumble upon your little film ! wonderful :)
this is a similar principle with what their doing with newer kevlar vests. a liquid behind kevlar that when struck by high velocity object hardens immediately.
so ridiculously well put. I love it.
I don't need a PhD in physics to know that I agree with this analysis
Moses must've use a LOAD of cornstarch to get him and his passengers to the other side of the Red Sea
Science never ceases to awe and inspire.

This is exactly how Quatermass started out and all kinds of trouble followed him about.
Put the cornstarch back in the cupboard.
Just mix water and cornstartch, see what you get, add more constarch until you get what you want. It's great fun
one of the strangest bits of science i've seen in a while
If they could motion capture that last "writhing finger" movement and blow it up to say, ten feet tall, It would make one heck of a movie special effect. Like some monster of the underworld bursting out of the ground.
I think you are almost right. I think there has to be a connection. more like the noisiness of the quantum levels. or even the fabric of time and space at quantum level
the last expirement looked horrific, like a bunch of people melting on each others and trying to escape hell
Yet another good example for cymatics.
Someday... Humans will realize how close this little experiment resembles time travel...
this stuff is cool, I made some at the place I work at today and my students really liked it.
im thinking about 3/4 cup of science and 1/4 cup of curiousity really made this project pop off!!!
"What if its how somehow linked to how the fabric of our universe works?"
It most probably is, I expected a terminator to climb out of it myself.
I will never look at corn muffins the same again.
yeah it kinda does, the beginning also reminded me of a germ colony in a petri dish.
TIP:
if you don't have that rotating plate, you can do what I have done.
use your sub-woofer (to whoever has a stereo system)
It works the same as that when the bas is high, its even easier to set as you want...
Non-newtonian liquid is so awesome to play with! i can spend hours holding it in my hands
that was creepy as hell but cool at the same time
it has to do with the wave frequency that is being sent through the object, like hold on to a rope that's waving, but instead of you holding onto it and it stopping it keeps waving despite the fact that your holding it, its all about getting the right frequency

Glass is only a liquid when it is melted, however it is FLUID at room temperatures (a fluid solid).
the mythbusters did a walk on water myth. where they ran across a pool of this stuff. but the second you stop running you fall into it like a liquid.
You can do the same thing with a cornstarch and water mixture. It's not fake. I think that the liquid in this video is a cornstarch and water mix because it acts very very much like one.
wow...thats probably one of the most interesting videos ive seen in awhile
keep up the good work =]
Thats a rather amazing physical reaction... worth watching just for the effect. Thanks for posting.
Today, i will try to make the dead rise
Thank you Brianso8,

its just corn starch and water make it yourself its cool you leave it in your hand and it melts like liquid but if you hit it hard its like a solid.
Without nerds, you and me wouldn't be using the internet right now, nor would be be using computers.
Water + cornstarch = a freakin monster!
that last bit looked like a scene from a sweet zombie flick.
Fascinating stuff. This material is basically very fine mud... I'm wondering about the practical applications wrt earthquakes, where we see the opposite effect, ie. the earth's shaking causes seemingly solid ground to behave like a liquid.

that last bit with the finger like things is crazy!!! absolutely crazy
in simple terms....half solid, half liquid
the last one looked like mud people trying to climb out but are melting at the same time
Fun with physics! Very cool, I love this stuff. :)
Today, i will try to make the dead rise
for a minute there i thought i was watching a living creature.
i want to see the last experiment used as a demonstration for spread of disease in some zombie movie. that would make my day

This is called "cymatics". Fairly simple, all matter exists because of vibration or frequentie.
This is the coolest thing ever, especially the last part.
From the cornstarch and water .... LORD VOLDEMORT LIIIIIVES
This will totally revolutionize driving, with this on the road, the slow gammmars will be sucked in. while the fast, safe road users will be fine.
If you can't find a vibrator (lol, not that kind) for this kind of thing, perhaps you could make one with a slightly off-center weight and something that spins in which you can control the spinning speed, like a high quality motor.
this technology can lead us to space travel.
Crazy cool I used to make n play with that stuff 30yrs ago $ still it amazes me.

I think life was formed by very high pitched vibrations
the main thing is actually the container being used producing those waves
anyone else agree this would make a good screensaver?
I tried that with my usb massager, it was so freaky... put a few drops of the cornstarch+water mixture on it while it's vibrating and they did seem to come alive!
this is just cornflour and water, its pretty much primary school science.
Wow. Corn does everything imaginable! Its ironic because we cant properly digest it.
That's awesome, last one looks like dead rising from the earth.
I wonder if waves in the space-time continuum could act like this.
Very fine example of bending time and space with frequencies... Hhmm... Interesting. It's obvious that gravitational behavior against the substance is being altered. Think of the possibilities. Nice.
@salirezakm A loudspeaker.
Mix cornstarch with water, put it on a plastic film on top of a loudspeaker, hook it up to a tone generator, that is really all it takes.
It's cool stuff.
that last one BLEW MY MIND
you get cornstarch
you add water to it
good luck
Looks remarkably like the plasma on the surface of the sun.
The last one looked like the bucket was full of maggots.
That stuff was on Flintstones. I cannot believe that it's actually possible after all.
.... so .... freaking ... awesome ...
That last one was just awesome!
the last part can be used to create special effects in some scary movie.
it looks like people trying to get out of quicksand or zombies coming out of the ground
Kind of gives me the creeps. But it also fascinate me.
From a math point of view, this liquid, once opened the hole, keep invariant their topological propietry. Have you ever ask to a math theacher?
the last one looks like a zombie film
Not computer generated at all. When I was a kid I used to play with this all the time. Never did use a faraday wave- but no doubt in my mind it does what he says. So cheap to make- hours of fun and experiments
Did I just watch corn starch evolve?
honestly wish i had some sort of shaking thingy like that.... amazing
This is like a horror movie.
It's not fake at all. Quite amazing.
Lol yeah it's like a CGI effect from Akira..nicely done
it may be old but its true its called a non neutroian fluid or oobleak its in youtube search for it and u will see how it moves at different hz
thats creepy lol. its like scenes where the underworld boils up into earth making moaning noises.
Is this what we in the UK call Cornflour, white stuff you use to thicken sauces?
