Ferro Fluid Tests - Magnetic Liquid
Vložit
- čas přidán 19. 07. 2010
- Ferrofluid is a liquid that reacts to a magnetic field. It's usually made from a mixture of oil and tiny iron particles. Today we're going to look at 4 different demonstrations involving ferrofluid and powerful neodymium magnets.

I love how he randomly said "don't eat this" LOL
*Dont eat this* ...Damn that ball of magnetic sludge looked sooo tasty!
+Casey Edwards really you think
yeah lol
aww but I wanted to try it
+Ethan H if you try than try i dare you hahaha
+Ethan H me too!
Here's a suggestion :
-Eat a tiny video camera
-Drink some Ferro fluid
-Play with a magnet around your belly
idiot
It surprises me that some people think I was serious in that comment.Jesus...
Only took 5 years for that 60fps to kick in
3:51 I love how he just adds that comment XD
yeah just a random comment
"Don't eat this." LoL hahahaha
i did.
You explained it very well! You made it easy for me to understand chemistry!
This was the first ever video I watched from Dylan...may he rest in peace❤
"Don't eat this" 😂😂 seems legit
Could you have a powerful magnet attached to your body and thus create some sick alien armour by pouring it on yourself?!
Tottaly what I was thinking.
yea you could but not only the magnet would prob kill (ofc only if its rediculusly strong and if you would need to be quiet a long time but yea) you but armor could be pirced by a pinky so yea not much use in that
Well you could create Magnet Armor :P made out of pure Magnets
Interesting enough an idea similar to this is being researched. Rather than changing when in a magnetic field though, it's changed with the application of electricity, from a liquid to a solid.
nice imagination.
Officially my new favorite material :)
Great video!!
Pretty sure the Fe came from the word ferrous, not the other way around
lol
Technically it came from Ferrum which is Latin for iron.
***** And ferrum is where we got ferrous, which has a literal translation of "full of iron" but really means something along the lines of "sharing the properties of iron".
True dat, fakjbf.
I thought I implied the further etymological line. I appreciate the clarification.
The reason that makes you think of Spiderman is probably because venom, which was the strange black substance that fell from space and came out of a meteor, looks kinda identical in the weird way that it just kind of moved around. This was featured in Spiderman 3 during the scene where he was with Mary Jane in the park. :) FYI
Ferro fluid moves into different configurations depending on how close or far the magnet is and what direction the magnet is from the fluid. It made some cool shapes that looked like fractal formations.
Wow! Magical almost!
I like how at 3:45 there's this awkward silence, then he's like: Don't eat this...
Household Hacker when you put it on the plate and turned into a spikey ball, could you freeze it and have it as a spikey metal ball type thingy?
I actually made ferro fluid in chemistry class. It took about half an hour of mixing and chellating and condensing to get it down to the final product. Our team was finished first, and the professor and all the students came over to watch as we manipulated the fluid with a magnet. Fantastic fun in chemistry class.
Best line ever, "Don't Eat This" - I teach 7th grade science and I have to say this every single time we do a lab.🤣
Wow.. no.. The word 'ferrous' doesn't come from the atomic symbol for iron... The word for iron in Latin is "ferrum". Which is where the atomic symbol comes from - and where the prefix 'ferr-' meaning 'of or about iron' comes from.
+ The Werewolf You're cool .
Chris Brown Wow - very intelligent reply. I weep for your parents.
I was thinking that too. I'm sure he was just saying that to simplify it. Element symbols aren't made up lol
Why did it sound so funny when he said don't eat it
Ikr
+Zachary Walline I know right?
this looks sooo coool *O*
thanks science!
Cool video! 😘
"dont eat this" lmfao
why does this happen?? I'm doing this for my science fair project. What is the dependent, independent and control variable of this experiment??
4:36 IT LIVES
awesome vid!
and haha, almost thought you'd really eat it
3:52 Don't eat this. LOL
Very interesting. Thanks
2:37 *chough* venom *cough*
May the force be with you number one!
This is so satisfying
"Don't eat this." Well no shit sherlock. lol
there are always stupid people in the world who would
Think it makes u think of spiderman because of the venom symbiote
Since the spikes are formed partly because of the surface tension of the oil, I think it would be interesting to see what happens if you pour a surfactant, like liquid dish detergent, on it.
You're very welcome. ;) May the force be with you.
ok. ferrofluid is awesome. now how do you get it off the magnet?
If you are using an electro-magnet just turn the power off.
The word "ferrous" does NOT come from the Fe symbol on the periodic table. That makes as much sense as saying that "see you" came from the text-slang "cya". The symbol for iron came from the word "ferrous," not the other way around.
Thomas B Well, the symbol itself came from latin "ferrum", to be nitpicky. That etymology is much more obvious in French (iron is "fer" in French).
Woohoo! I love this stuff :-D
It was around 4:55 in when he's spinning that around the plate- I had my first glimpse of a new way I can visualize and model what an electron really is.
Ok, so my new model needs some work, but I feel good on the first intuit here.
They're not "treads" they're "threads," yes, the same word as the stuff you sew with.
Lol, I bet they used this stuff on Spider Man 3
+MusicalSoul haha
+MusicalSoul and black slime
They most probably did lol.
the ferro fluid suit
I really thought you were gonna drink it -_- Epic project
This would be really epic for the science fair!
Anyone know why dy magnets doesnt attract our blood? RBC contain ferum and iron.
The amount of ferrum/iron (ferrum is a synonym for iron) isn't enough for the magnets to get visibly attracted to them.
I am about to Google this... my name tag for work is kept in place by some type of magnet. There is a non-magnetized plate on the back of the name tag & then there is a very powerful magnet that goes inside my shirt. I have noticed that after working all day the spot where me magnet rested on my chest was sore & red. I am curious if it is due to me either being allergic to the substance that makes up the magnet, or if the magnetic field itself was to blame?
You'll be amazed how little iron there is in the human body
ksalbrecht88 You are most likely to be allergic to the nickel plating on the metal bar that goes under your shirt. Try wrapping the magnet bar with a layer of cling wrap. If it ever causes you to break out with blisters, see a dermatologist.
First off, even the strongest small magnets like this have to be very close to have a strong pull on anything... then there's the fact that there really isn't much Iron in our blood.
I've heard, that if you were to wear strong magnetic jewelry long enough, it could have negative side effects due to pulling too much iron to one part of your body... google it yourself, and remember, everything you read on the internet, IS TRUE.
Don't worry. If you eat it just swallow a magnet and it'll harmlessly draw all the ferrofluid to it then you poop it out (:
AWESOME!!!
Awesome!
i feel like the liquid will come alive and kill me.
then you sir need to try my phsyciatryst
LOL
+Dub Step - lol the way you spelled psychiatrist.
really good 720p60 in 2010
+Geralt Nt oh dayum
I wrote my assignment on this stuff. Everyone loved it.
Just imagine if magneto was an engineer. :P
if he got near the stuff he would probably drown himself in it
POOT DISPENSER HERE
+Dr Scrubbington ⟨InfinityV0rtex⟩ ahhh this is bad!leave me tf2
Makes you think of spider-man because of venom.
I love how it spikes up.
I almost had a heart attack in the end, I thought you were actually gonna drink it!!
I feel like I'm being condescended to in this video T_T
Venom! :)
"for some reason this makes me think of spiderman..." "not sure why"
Can you actually solid it? to make it keep shape without geting oil on other places? Looks cool.
The whole time I was thinking venom
+That's him officer yep
+Bernard Isosceles what happened the apostrophe in that's?
I was doing a +. It isn't my account, so I don't know.
I wanna eat it!
its oil and iron you really wanna try, you'll probably die.
deandra storie You're right.. Maybe I should try again.
deandra storie shhh... let natural selection take its course :)
TheLightningWhale Your not my sibling :/
Dear household hacker,
I bought some ferro fluid a while back, and I put it in a jar ( coated on the inside with waterproof spray, however, it was for shoes). Anyway, when I out the fluid in the jar it left oil stains on the sides. What do you suggest to coat it with?
Any reply would be great, thanks :)
How did you get the spikes? I have tried a lot of oil+toner mixtures but NEVER got it, even with strong neodymium magnet.
BTW, the mixture that you suggested (oil+toner) is less dense than water, so, in your experiments (at 2:20'') you used another kind of formula, didn't you?
Could you give it to us?
Thanks in advance.
.......... Don't eat this.............
... dont eat this
I wonder if flow could be achieved by running this fluid through a loop of tubing with spaced electromagnets? Perhaps if some sort of coolant can be mixed in without losing either the magnetic or heat transferring properties, a cooling system that runs on less energy than one requiring a pump could be designed?
Where do you get those Ferro Fluid? Its awesomr
oh dam i was looking forward to eating that big ball of poisonous goodness
Shit.. I ate it!!
Look on the bright side Jaden. Even after drinking the Ferro fluid, that is still the second most bone-headed thing you have done in your life. That god awful "After Earth" movie still tops it.
just randomly. "dont eat this." you have so much faith.
This video made me hungry, and right as it started doing so, it came to the part where he said "don't eat this".
another weakness of venom, magnets
cool
!!!
also sound
yo Anish Alluri
WHAT HAPPENS WHEN YOU TOUCH IT :D
That's what I'm thinking...
ikr
Omg Yeah!
Kodey Neesam it stains your hands but it doesn't hurt
:o
Ferrofluids are some of the most surreal things that exist irl.
DAMN THAT WAS COOL
AMAZENG!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Hi, question: When you put a rare magnet near magnetical liquid, it sticks to it and takes the form, but does it becomes solid(hard) If you touch it with finger after it sticked to magent?? does it still solid or it still liquid? i mean from liquid state to solid state? I mean when u touch it, it doenst changes its shape or doesn't it? Sorry for my mistakes, English is not my main.
Can you leave this in the water for like a good long while to play with time and time again? Or does it dilute into the water? Thanks!
Wow കിടു 😍
RIP Dylan Hart ❤️
At 0:54, I don't mean to be a nerd, but the symbol on the periodic table is not the reason why we call them Ferrous metals. In fact, it's the other way around- Fe represents the word Ferrum, which is the Latin name for Iron (and thereby the reason these are called ferrofluids.) Regardless, this is a fantastic video, I love it!
...also, 3:52 LOL!
Yes, it is ( he did this in his last video on ferro fluid). as long as you don't drink it or anything.
very interesting!!!!!!!!!!!
While it was moving at the end did the magnet sink to the bottom of the ball or did the ferrofluid prevent that from happening?
Question: Is it possible to use an absorbent material and a magnet to separate all the small iron particles from the fluid?
This is Awesome! Btw, it's not SpiderMan u should be thinking about, but Venom.
This vid is really cool! He even tells us not to eat the stuff lol X)
Nice !!! I'm actually doing a project demonstrating this substance ! can you tell me which type of magnet do you use it seems strong??
"Ferrofluid is a liquid that reacts to a magnetic field. It's usually
made from a mixture of oil and tiny iron particles. Today we're going to
look at 4 different demonstrations involving ferrofluid and powerful
neodymium magnets." It was in the video description...
can you separate the Ferro fluid from the magnet once its on or is it permanent?
THIS IS AWESOME!!!! I DID THIS FOR A SCIENCE PROJECT!!!! INSTANT A+!!! Thanks house hold hacker
really?
that's cool
HOW DO YOU GET THE FERROFLUID OFF THE MAGNET!!!!!
where did you find the rarest magnet ?
At any hardware store. I wouldn't try home depot though, I cant confirm that they have neodymium magnets.
Ray McMillan Another magnet. LOL. There are several other videos on this made by the same person. Go check out those videos to see if he shoes how to get the Ferro-fluid of the magnet.
Wow😮awesome
that is the coolest thing ever where can i get some
are you going to get on PBS soon !
please tell the exact brand specifications of the toner used for your experiment?????????????
Wooow I love it maan
"Don't eat this."
Love it.
"Dont eat this". I nearly died laughing!
What would it be like to touch once the magnet had been dropped in it? Would it feel firm or just like liquid?
i love how he just says out of nowhere “dont eat this.” LOL
would this expirement fall under chemistry or physics mostly. if i were to do a demonstration for class?
Its in the magnetic ride control on cars like the Chevrolet corvettes they had installed in 2003 on the c5 corvette.
Can you also make red or yellow goo like with copper and other colors with other materials?
