It's called natural human curiosity and is part of our natural predisposition, that we like to explore, discover, understand and learn things. It's there to make us we are able to understand the purpose of our existence.
That's one of the best parts for me. If I ever find a video by The Action Lab that he doesn't say "This is so cool" in I'd be just a little disappointed. I'd still watch, but it just wouldn't carry the same sense of wonder as some of the others he's understandably gotten excited about. That's just me, though.
The way it goes from thin liquid to nearly solid gave me a really cool sci-fi tech idea... imagine a curtain of ferrofluid pouring down as a sheet in a doorway, getting recycled from a drain at the bottom, and the door frame has magnets arranged to solidify it when they're on. When it's off, the magnets turn off and the liquid stops pouring. So that lets it pour in a nice sheet but then solidify on the way down, giving you basically a liquid door that's still solid to try and walk through.
As fun as that would be, ferrofluid would stick to the magnetic forces if they were to be made "solid" like this. A great idea, but requires some form of projected suspension method to keep it all door shaped without having an actual door there.
@@Artik_Masterson Is it not possible to have the right arrangement and/or movement of magnetic fields such that they form a relatively door-shaped field?
@@IceMetalPunk not really. The ferrofluid has to stick to the source of the magnetism in order to be dense enough that it becomes hard to pass through. Magnetic fields are circular/spherical in shape, and with how it all works physically, in order to make a door with ferrofluid you would have to break the laws of physics. I don't recall if there is any way for a magnetic field to take on a particular shape, but that would be about the only way to make a wall of ferro fluid....I think
Back in the day, when Disk drives were only as big as 40MB, we used to use ferrofluid to paint on the disks looking for defects under a microscope. It was called developing the disk. It was a means for us to determine a possible cause for data errors from disc defects, or even head crashes. It was fun to play with but as you showed, it could be VERY messy! It wasn't quite as black and thick as your stuff but had more of a yellowish oily suspension fluid.
It could also be used to read magnetic strips on credit cards. I showed that to people who weren't happy I could read the bits. I had the stuff for servicing machines at work.
@@eeveeofalltrades4780 could do a sealed plexiglass box with gloves that reach through the walls of the box. But the problem is that it would be expensive to keep adding ferro fluid all the time

“This is the weirdest thing I’ve ever felt” That’s crazy.. considering this man has done probably hundreds if not thousands of different physics/chemical/electromagnetic experiments in his life... That makes me really want to see what that feels like one day.
yeah then again some people say that vr is the craziest thing ever but that just made me disappointed. Sure it's realistic but it doesn't really trick you.
I actually had a chance to touch some in college. Have you ever held or touched a condom full of water? It kinda feels like that except now imagine if you pushed hard enough your hand would go inside of it and you would constantly feel this dull repulsion effect on your hands as if it is trying to expel your hands out of its mass. Kinda like how if you attempt to press two same pole magnets together they will repel each other. I like to think its how a slime would feel like in an RPG.
This video made me realize that ferrofluid in a strong magnetic field is a good simulation of a super-dense liquid, could be some cool applications here
I was imagining a large spherical bath of super strong (superconducting?) ferrofluid, that was itself within a very larger, superconducting magnet, all to force incredible pressure in the very center for, like, fusion or whatnot.
Yeah, I was thinking the same. That then made me wonder whether a Ferrofluid could act as a barrier between 2 other fluids -- like a barrier between water and air, or a barrier between air and some other gas. I was reading that there are some ionic liquids like polyphenyl ether that are thick like molasses and have a very slow rate of evaporation into space. I was thinking that perhaps if a ferrofluid could be made from something like that, then it could act as a barrier between an air-filled compartment and the vacuum of outer space (sort of like that hangar-bay force field on Star Trek)
In mathematics, the magnetic field itself would be considered a force field, a field of vectors that exert a force. There's a whole world of equations to figure out how things behave within this field. (This is Calculus 3)
And then the daim ailgun behaivor too. Might be something. If the ferrofluid is locked onto the superconducter directly, will it not stay as a layer floating in space with limilar behaivors? Force field.
It’d be interesting to see it on a hydrophobic surface. It might make it easier to actually see the structure of the magnetized ferrofluid as it might not stick to the surface it’s on. Hydrophobic gloves could work well too
Seeing a liquid turn into cones floating above a superconductor… Also speaking of superconductors, the fact that a magnet as strong as the one shown later doesn’t have a superconducting coil and thousands of amps is insane. It’s so impressive and terrifying. It’s like a condensed scrapyard electromagnet that doesn’t have a switch. I’m blown away that the fluid came out of the cup the way it did. I expected it to start out as an overwhelming struggle to keep the cup steady, followed by a huge spill onto the magnet and a thump as it falls into place. This is enormously interesting.
*What if you were using this Ferrofluid underwater? Could you still control it underwater? Could you use it to make a sort of hatch or door that separates an air-filled compartment from a water-filled compartment? Can it hold back air pressure or water pressure?*
This is the craziest thing I have ever seen. I have always been fascinated by magnets but this demonstration is on another level. Well done The Action Lab.
Well based on the Schrodinger's Cat thought experiment that is possible though it would be in a quantum superposition of being soft and hard at the same time.
@@ryansizemore5064 yes powder can be soft. I watched a show where they made a "trap" at the end of a driveway. They made a boxed in area with some sort of dirt that when just sitting there, cars could drive over, but if you shot air to it from several points underneath for a split second, then the car would sink. And it did.
always enjoy watching your videos. I have a question for you which might make a pretty awesome video... Have you ever tried adding vibration to this mix? As in sound vibration? Will something happen to the ferrofluid when you add sound vibration at the point where you had the big magnet on the other side of the perspex and that amount of ferrofluid at 4:30 in the video? Like a tone generator or putting a magnet on a speaker and covering that magnet with ferrofluid.. When i say sound vibration I mean when you use salt of grains on a metal plate and a tone generator and add sound vibrations to create the different patterns from the vibrations.. I'm not sure if what I say makes sense but would be interesting to know if it would affect the ferrow fluid somehow.
Grown ups don’t give up toys, they just get better ones. Magnets are like playing with a tiny planet with noticeable local gravity correlated to its size, damn I like that stuff.
That could be super interesting. What happens when you combine fumed silica and ferrofluid? Fumed silica is nearly insoluble in organic solvents and acids (except hydrofluoric acid,) so it wouldn't form a solution with the ferrofluid, but I have to assume it would interfere with the normal behavior somehow. Or what if a magnet was made hydrophobic and then ferrofluid was introduced to the hydrophobic surface. It would want to roll off the edge, but I'm interested in what would happen before the ferrofluif rolls off the edge.
I think it would be cool to see what is denser; Water or hydrophobic ferro-fluid. I hypothesis that if water is denser, you'll have a cool blob ontop of the water. I imagine if you set one up in a pool with a strong magnet it could look like a black monster scurrying around. If the fluid is denser than water though, you could have a simular underwater effect. Either way would be cool.
Actually you cannot coat Ferrofluid with Hydrophobic substances as Ferrofluid has surfactants and it's actually dispersed in kerosene or organic Solvents........
None equilibrium property of an unchanged particle is not is selected from the group consisting the immediate spread direction to form an equilibria into infinity that spirals into the quanta World
No, it's basically just liquid iron. It's not that the liquid in particular is denser when near magnets, it's just that, because it's magnetic, it gets pulled against the glass causing it to get denser as a side effect.
I wonder what would happen if you suspended the ferro fluid over a speaker.... And then hit it with different frequencies. For example from one of your previous videos where you were trying to blow out a match.
We don't live in a "universe" we live on Earth. It's just Hell, Earth, Heaven. Universe means "spoken sentence" - AKA, when God said "Let there be light." It's time to wake up. Space is a lie. It's cartoons for adults. You'll never go to Mars, or the Moon, because they're lights - just like the Bible says. Nobody has or ever will escape Earth because there is a FIRMAMENT. Psalms 19:1 is written on Von Braun's headstone.
Dude, if you get nano iron particles would they lock around the magnetic field to see the field in detail? Also, you should put a coil around it and show what putting a current throught he wire does to the magnetic field and Ferro fluid/dust
(TL;DR search TH-cam for "magnetic field viewing film" for a better way to see the shape of a magnetic field) I always found it slightly frustrating that most descriptions of magnetic fields talk about "field lines" without explaining (or without explaining very well) that they are just conceptual aids that are not physical, and then go on to show iron filings lining up along these "field lines" without explaining what causes that and thus giving the impression that magnetic fields have this complex internal structure of physical "field lines" that the iron filings are revealing. Magnetic fields are continuous and there are no "lines" unless the field is a complex interaction of many different magnetic domains with different alignments and / or strengths in different places. This latter is actually what happens with iron filings and what causes them to clump up and align into lines. Because the iron filings are ferromagnetic and also long and thin, when they're placed in the magnetic field, they become magnetized and turn into tiny bar magnets and then rotate to align themselves with the field in the area around them like a compass. But because they're all tiny bar magnets, they also attract each other, so areas with a slightly density will pull filings from areas with a slightly lower density, causing them to bunch up into filaments oriented along with the magnetic field. So the filaments seen with iron filings near a magnet are caused by a combination of the magnetic field and self-interactions between the filings. The same thing happens with ferrofluid to cause the spikes: at the surface, the iron in the fluid wants to bunch together into filaments but is fighting against both gravity and the surface tension of the fluid, leading to a series of rounded spikes instead of filaments. If you want to get a better idea of the continuous nature of a magnetic field, you would ideally have the "filings" be as small as possible, able to rotate in place to show the direction and orientation of the field, but also fixed in their location so they can't clump together to form filaments. This is exactly what magnetic field viewing film does, and it's awesome for getting a better sense of what the field "looks like. Physics Girl made a good video with magnetic field viewing film a few years ago: th-cam.com/video/HodWkE0G28M/w-d-xo.html Something that would be really amazing if someone figured out how to make it work is something like a gel with embedded ferromagnetic nanoparticles which are somehow mostly transparent when randomly aligned but which become visible when aligned with a magnetic field, so that it would be like the magnetic film but in three dimensions like the ferrofluid.
Fascinating content! Essentially, you have a fluid which employs a magnetic field to vary the fluid density. An expansion of this experiment might utilize a powerful electromagnet to allow for electric variable control of the field, & therefore fluid density. Doing this could possibly allow you to alter the effective buoyancy of other dense objects in the fluid, like making a rock sink, suspend or float by turning a potentiometer. Could be interesting to observe the behavior of mercury or gallium in such conditions as well.
I’ve always loved science and experiments. Your videos really take me back to a childhood fascination brought out by the fun science teacher. Thank you for the content you produce!
Very cool, would be interesting to see with some vibrations introduced. Different frequencies, I imagine that could create some really weird shapes and movement
I would have liked you to describe the texture and feel more. Is it bumpy or smooth feeling on the surface? Is there a pressure or weight on your hands when they are submerged (aside from the actual weight)? If you make a wave from one side can you feel it with a submerged hand? Do you feel a flow or movement under the surface when your hands are still?
Use of such fluid in electro-dynamic suspension can produce active active damping control & some innovate car suspension systems, like the one that Porches himself developed, leverage this controllable magnetic effect to achieve unmatched vehicle stabilization // vibration reduction // suspension damping excellence, but its very expensive //
it would either be incredibly expensive or just not possible, you’d have to have magnetic repulsion in the perfect range of power to not bottom out constantly or be maxed out especially with added weight, it’d be very very cool to see someday though

In mathematics, the magnetic field itself would be considered a force field, a field of vectors that exert a force. There's a whole world of equations to figure out how things behave within this field. (This is Calculus 3)
@@WavyCats - it's matter, not empty space - by that standard, you could declare all matter to be a "force field"
And then the daim ailgun behaivor too. Might be something. If the ferrofluid is locked onto the superconducter directly, will it not stay as a layer floating in space with limilar behaivors? Force field.

Now you can make a body suit of small magnets, cover it with ferro fluid and make your own venom suit.
Send this idea to the Hacksmith, He would legit do this if it were possible.
I mean if we think about it you just need a glove that has enough relatively strong magnets weaved into it right then dipped into the fluid
Did any one else hold thier breath, waiting for the fluid to start crawling up his arms and forming a 'venom' suit.? LOL

It’d be interesting to see it on a hydrophobic surface. It might make it easier to actually see the structure of the magnetized ferrofluid as it might not stick to the surface it’s on. Hydrophobic gloves could work well too
Does hydrophobic stuff repel all fluids or only water?
@@silvermeta2421 it is just water and some iron; so should work
@@falahati Oh ok.
Bro it's 2021 we shouldn't encourage hydrophobic behavior :)
Seeing a liquid turn into cones floating above a superconductor… Also speaking of superconductors, the fact that a magnet as strong as the one shown later doesn’t have a superconducting coil and thousands of amps is insane. It’s so impressive and terrifying. It’s like a condensed scrapyard electromagnet that doesn’t have a switch. I’m blown away that the fluid came out of the cup the way it did. I expected it to start out as an overwhelming struggle to keep the cup steady, followed by a huge spill onto the magnet and a thump as it falls into place. This is enormously interesting.
*What if you were using this Ferrofluid underwater? Could you still control it underwater? Could you use it to make a sort of hatch or door that separates an air-filled compartment from a water-filled compartment? Can it hold back air pressure or water pressure?*
Those are some bold questions.
Now I also need to know
air pressure yes but idk about water since it would have to be scaled up massively to hide you secret base

@@ryansizemore5064 yes powder can be soft. I watched a show where they made a "trap" at the end of a driveway. They made a boxed in area with some sort of dirt that when just sitting there, cars could drive over, but if you shot air to it from several points underneath for a split second, then the car would sink. And it did.
Just curious.... What age? My daughter used to say silly things, but is older now.
always enjoy watching your videos. I have a question for you which might make a pretty awesome video... Have you ever tried adding vibration to this mix? As in sound vibration? Will something happen to the ferrofluid when you add sound vibration at the point where you had the big magnet on the other side of the perspex and that amount of ferrofluid at 4:30 in the video? Like a tone generator or putting a magnet on a speaker and covering that magnet with ferrofluid.. When i say sound vibration I mean when you use salt of grains on a metal plate and a tone generator and add sound vibrations to create the different patterns from the vibrations.. I'm not sure if what I say makes sense but would be interesting to know if it would affect the ferrow fluid somehow.
Grown ups don’t give up toys, they just get better ones.
Magnets are like playing with a tiny planet with noticeable local gravity correlated to its size, damn I like that stuff.

I would like to see the ferro-fluid combined with hydrophobic property or maybe using a hydrophobic surface. That'd be so cool!!
That could be super interesting. What happens when you combine fumed silica and ferrofluid? Fumed silica is nearly insoluble in organic solvents and acids (except hydrofluoric acid,) so it wouldn't form a solution with the ferrofluid, but I have to assume it would interfere with the normal behavior somehow. Or what if a magnet was made hydrophobic and then ferrofluid was introduced to the hydrophobic surface. It would want to roll off the edge, but I'm interested in what would happen before the ferrofluif rolls off the edge.
@@ObeyCamp Yeah, I think it would float on the magnet due to the force but just barely touching it due to hydrophobic property.
I think it would be cool to see what is denser; Water or hydrophobic ferro-fluid.
I hypothesis that if water is denser, you'll have a cool blob ontop of the water. I imagine if you set one up in a pool with a strong magnet it could look like a black monster scurrying around.
If the fluid is denser than water though, you could have a simular underwater effect.
Either way would be cool.
Actually you cannot coat Ferrofluid with Hydrophobic substances as Ferrofluid has surfactants and it's actually dispersed in kerosene or organic Solvents........
None equilibrium property of an unchanged particle is not is selected from the group consisting the immediate spread direction to form an equilibria into infinity that spirals into the quanta World
So it's like a liquid who's density is dependant on the strength of a magnetic field affecting it?
I'd say it's more just being tugged so hard by the magnet that it gets denser as a result
No, it's basically just liquid iron. It's not that the liquid in particular is denser when near magnets, it's just that, because it's magnetic, it gets pulled against the glass causing it to get denser as a side effect.
@@supercr33p3r7 Liquid iron? oh wow hes a literall superhuman that could touch a 1400 celcius Liquid iron

I wonder what would happen if you suspended the ferro fluid over a speaker.... And then hit it with different frequencies. For example from one of your previous videos where you were trying to blow out a match.
The joy of watching this video was somewhat spoiled all the time by my thoughts of cleaning up the mess.

We don't live in a "universe" we live on Earth. It's just Hell, Earth, Heaven. Universe means "spoken sentence" - AKA, when God said "Let there be light." It's time to wake up. Space is a lie. It's cartoons for adults. You'll never go to Mars, or the Moon, because they're lights - just like the Bible says. Nobody has or ever will escape Earth because there is a FIRMAMENT. Psalms 19:1 is written on Von Braun's headstone.

Dude, if you get nano iron particles would they lock around the magnetic field to see the field in detail? Also, you should put a coil around it and show what putting a current throught he wire does to the magnetic field and Ferro fluid/dust
(TL;DR search TH-cam for "magnetic field viewing film" for a better way to see the shape of a magnetic field)
I always found it slightly frustrating that most descriptions of magnetic fields talk about "field lines" without explaining (or without explaining very well) that they are just conceptual aids that are not physical, and then go on to show iron filings lining up along these "field lines" without explaining what causes that and thus giving the impression that magnetic fields have this complex internal structure of physical "field lines" that the iron filings are revealing.
Magnetic fields are continuous and there are no "lines" unless the field is a complex interaction of many different magnetic domains with different alignments and / or strengths in different places. This latter is actually what happens with iron filings and what causes them to clump up and align into lines. Because the iron filings are ferromagnetic and also long and thin, when they're placed in the magnetic field, they become magnetized and turn into tiny bar magnets and then rotate to align themselves with the field in the area around them like a compass. But because they're all tiny bar magnets, they also attract each other, so areas with a slightly density will pull filings from areas with a slightly lower density, causing them to bunch up into filaments oriented along with the magnetic field. So the filaments seen with iron filings near a magnet are caused by a combination of the magnetic field and self-interactions between the filings. The same thing happens with ferrofluid to cause the spikes: at the surface, the iron in the fluid wants to bunch together into filaments but is fighting against both gravity and the surface tension of the fluid, leading to a series of rounded spikes instead of filaments.
If you want to get a better idea of the continuous nature of a magnetic field, you would ideally have the "filings" be as small as possible, able to rotate in place to show the direction and orientation of the field, but also fixed in their location so they can't clump together to form filaments. This is exactly what magnetic field viewing film does, and it's awesome for getting a better sense of what the field "looks like. Physics Girl made a good video with magnetic field viewing film a few years ago: th-cam.com/video/HodWkE0G28M/w-d-xo.html
Something that would be really amazing if someone figured out how to make it work is something like a gel with embedded ferromagnetic nanoparticles which are somehow mostly transparent when randomly aligned but which become visible when aligned with a magnetic field, so that it would be like the magnetic film but in three dimensions like the ferrofluid.
@@MasterBunnyFu Came here to say the same
6:25 “Sorry, You have to be level 21 to enter this area!”
Fascinating content! Essentially, you have a fluid which employs a magnetic field to vary the fluid density. An expansion of this experiment might utilize a powerful electromagnet to allow for electric variable control of the field, & therefore fluid density. Doing this could possibly allow you to alter the effective buoyancy of other dense objects in the fluid, like making a rock sink, suspend or float by turning a potentiometer. Could be interesting to observe the behavior of mercury or gallium in such conditions as well.

I would have liked you to describe the texture and feel more. Is it bumpy or smooth feeling on the surface? Is there a pressure or weight on your hands when they are submerged (aside from the actual weight)? If you make a wave from one side can you feel it with a submerged hand? Do you feel a flow or movement under the surface when your hands are still?
It is actually a ordinary liquid with an shape so it is pretty smooth also since it is denser than the hand your hand would get pushed out
This was absolutely remarkable. Thank you for your research.

Use of such fluid in electro-dynamic suspension can produce active active damping control & some innovate car suspension systems, like the one that Porches himself developed, leverage this controllable magnetic effect to achieve unmatched vehicle stabilization // vibration reduction // suspension damping excellence, but its very expensive //
it would either be incredibly expensive or just not possible, you’d have to have magnetic repulsion in the perfect range of power to not bottom out constantly or be maxed out especially with added weight, it’d be very very cool to see someday though
