I Like how he starts showing us this super crazy stuff and the gets lost playing with it while the camera keeps going

You can tell he was having a ton of fun because he wasn't talking as much after he felt it.

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.

*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?*

Just casually levitating big hunks of metal like a wizard.

When you tested it with the monster magnet, you created a lifeless slime, very interesting still

4:28 that swirl was so COOL!

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.

Next week on action lab: "Okay guys, this is the world's darkest ferrofluid, let's see what happens when I paint my house with it."

This was amazing to watch, I love how you were so baffled by this! How much ferrofluid would it take to see the spikes formed by the magnetic field of the earth? How many swimming pools of the stuff? Any intuition from playing around with it?

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?

Yet another random cool thing I am learning that will 99.9999% not be applied to anything I do in my personal life.

imagine someone showing you this in the medieval days

That clean up after the demonstration with the monster magnet really messed with me. He showed coins bouncing off of the liquid and getting ejected by it, but then casually scoops it up in a cup and pours it out, the structure just immediately crumbles without a magnet. Super cool!

this is such.. much.. work..setting all this up for making content out of it.. And it deserves so much more likes..

This was absolutely remarkable. Thank you for your research.

Step1:swollow a magnet Step2:cover yourself with this stuff Step3:WE ARE VENOM

Everyone should feel magnetic fields like this. This should be something in science museums everywhere IMO.

Lets take a moment to appreciate how everytime we get to see something new and interesting.. thanks action lab

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.

The violon combined with the gravity defying black moving liquid at 4:20 makes it look like you're creating some kind of eldrich creature

Yup, and this is the true story of how venom was born. The dude with the gloves is the future venom.

Incredible experiment. Thank you.

I like your videos. I wish there was a way to impose the magnetic field so we could see it directly as you manipulate it. That would be cool.

Gotta love how hovering objects has just become normal now

And as well, music was great.... Cheers!

ABSOLUTELY AMAZING..

The music made me feel like the fluid was going to come to life and go on a killer rampage

Imagine a sea of Ferro fluid with a giant magnet at the bottom

For the few wondering why you can’t make ferrofluid float by itself with a super conductor. It’s because the magic black substance unfortunately isn’t made of magnetic particles and instead is just attracted to magnets so you can’t lock it to superconductors. Which would be really cool

I always love your videos. I learn a lot from them.

This is exactly what I wanna watch after I get dummy high

Question: what's the worst experience you've had with one of those neodymium magnets?

This is amazing! Thank you! 🙏

Good combination of two cool things. Give me a bit of child like joy seeing this stuff

My daughter said, "have u ever thought that's rocks are all soft until you touch them?". Maybe she's right. 🤔

Alternate tittle: A grown man playing with questionable liquid and explain it

Yeah thanks to you I just solved a idea for a invention that will change stuff forever thanks.

Did he just play with his soft and hard junk? That’s SO AMAZING!!

Now you can make a body suit of small magnets, cover it with ferro fluid and make your own venom suit.

6:20 This is kinda like throwing money at Sony to get a PS5

This is so freaking cool looking reminds me of the venom suit way it moves and sticks together

If the physical resistance goes up evenly as you push more into the fluid it might be useful for shock absorption. Airbags for example!

"That was amazing. But now let's see what happens when I chuck a liter of ferrofluid down my throat."

In the next video, Hey guys, today I'm gonna be showing what happens when you drink ferro-fluid and sleep on a super magnet.

Very nice video.. ooh and by the way 'it dies everything it touches' cant describe why but I thought that was funny to mention that like that at the end

That’s one of the coolest things I’ve ever seen!

It’s awesome just to see objects float like it’s nothing at action lab this mans a wizard

What I find interesting is that despite the strong magnetic field from the Neodynium magnet, the ferrofluid still sticks to the gloves! So the adhesive force between the gloves and the ferrofluid is stronger than the magnet attraction. I would have thought that the gloves would come out clean, as the ferro fluid would have been sucked off by the magnet field.

You are probably one of the most brilliant people on earth 😊🎶🎹

Bro can you think of a way to generate electricity from ferrous fluid or magnetic ferrous fluid with powdered or nanno copper in it in a perpetual motion liquid running for example between magnets and in some of it moving the Manets?? or using mercury and the perpetual motion fluid or what ever idea. or using the idea of bladeless pumps

Venom looked exceptionally fluffy this evening. :3 This was super cool, thanks for sharing! :D

Can we all appreciate the work and mess and cleaning that he had to go through to make this video? Thank you for sacrificing the cleanliness of your garage for us James.

Does pouring or agitation of the fluid cause any spurious radio waves. Like you could use an old portable AM radio to cycle through the band to detect small disturbance in that band.

History will look back on this in awe & trip on how on the nose this was.

Who else feels like the gap between these videos feels like a eternity

“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.

i would love to see a video of this reacting to sound waves with speakers or something like that

You are the coolest ever man. Thank you for your content.

Its so satisfying to watch when the liquids that are being poured, it curves like it denies gravity and goes with the flow

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

Tanks for the info

Just the concept of ferrofluid is already mind boggling to me. I wonder if the fluid rusts.

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.

Which episode of The Action Lab is your favourite, Billy? "The one where the guy touches a magnetic liquid boob for a loooong time!"

Thanks for such a wonderful video!

Ferrofluid reminds me of the Rev-9 Terminator as portrayed by actor Gabriel Luna from the Terminator film 'Dark Fate'. Despite of these interesting scientific parallels that fuses itself with science fiction makes one question the interesting scientific exotic properties from ferrofluid has to offer in the wake of further scientific discoveries in the near future under ongoing research and development! Although it's not entirely irrational to consider that whenever it comes to science fiction then it usually often paves it's way towards that of science fact!

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 feel like this was actually just a teaser for the Venom Origin story...

Love this channel!

This was amazing but the really trippy part was when you scooped it up like a solid only to watch it pour out in the bowl like a liquid.

I LOVE that he is just as amazed and surprised as we are lmaoo

If this was science class not only would I be entertained but I would also get an A+

Alternate title: "Man harasses venom symbiote"

F.F. wax used for gm's magnetic ride control and sprt suspension btw

6:25 “Sorry, You have to be level 21 to enter this area!”

What I love about this channel is it concentrates more on the awe and less on the technical details. Technical details are great and there are channels which do that, but sometimes you just want to marvel at the majesty of it all.

Could be used for some amazing sci fi practical effects.

I suddenly realized I'd owned a trinket like this. A plug in magnet base with a world globe that hovered in space over it. It was pretty cool but I get power outages all the time. So each time the magnet would turn off and the globe would drop. Getting that big globe into the exact correct position to float was a massive pain so its packed away now. The other issue was the globe was big, so it wasn't always easy to see the space between it and the magnet. If you don't know its floating, its not cool. Still a nifty item, with the proper set up.

I've never seen anything like this before , am I the only one amazed beyond comprehension???😂

The way you describe how its takes force to enter the fluid when on the large magnet sounds about like what I imagine a force field does.

Satisfying. I wish had the fluid

The experiments I wish I could do if I had endless garage play time like you, thank you for doing them. I’m having just as much fun as you in a way.

Watching those magnets floating with ferrofluid sure is one of the most satisfying thing ever in UKposts.

The way the fluid appears to get denser in the presence of a strong magnetic field is exactly the principle behind how the semi-active Magne-Ride suspension system works.

What would happen if you put a hydrophobic coating on your gloves or the container?

I can’t imagine cleaning this up. Thanks for doing it so we don’t have to

You can actually feel and visualize all the magnetic forces passing through the fluid. That’s actually amazing and it’s something I want to experience

Incredible.

Ferrofluid becomes more dense as the magnetic field increases. It can therefore be used to sort a mixture of various metals by submerging them in a vat of ferrofluid and then subjecting the vat to increasingly intense magnetic fields. The various metals will float to the surface as the field intensifies and can therefore be sorted.

uh man it looks surreal, never heard about this before this channel is awesome, lucky to found

I would like to see the ferro-fluid combined with hydrophobic property or maybe using a hydrophobic surface. That'd be so cool!!

I noticed that it is a great absorber of lights despite being a liquid cyrstal. maybe such structures exist in more places. :)

Imagine thousands of ferro fluid cushions on some kind of alternative railway for trains to slide over with almost no resistance. I look forward to superconductors ect being used in the future

This the coolest video I have ever seen. Let's appreciate the efforts he makes to make these all possible for us.

Imagine using a ferrofluid wall as a test of strength. Only the worthy may pass.

When you realize that a couple hundred years from now this tech will be the inspiration for the real T1000. Watching him scoop a liquid out of mid air blew my mind.

What if you put a strong neodymium magnet on the end of a top or beyblade and made an almost frictionless top? Would it spin forever?

My eyes teared up a bit I think over how intensely magical this is.
