Ferrofluid demonstration

[ergurney]

Actually that's a lag screw.

[tantricsam]

Magnetically charged screw.. Then add oil containing iron filings... Stupid!!

[liamvanvel1996]

@tantricsam actually google ferrofluid it doesn't conatain iron filings so you're stupid

[Filo127]

I dont need a demonstration , i need an explanation !

[APHRODITEEEEEE]

spiderman hates this..

[coffie66]

Does this stuff remind anyone else of that cosmic gunk from Spiderman 3?

[agustaf4s]

does it ever dry, or is it always in a liquid state?

[P4r4k]

Why Modern Toys arent just like that? I wish I could have some! so I could inject myself and become Wolverine :D

[qazman4]

@P4r4k to make it take iron wool burn it, grade it, take the remaining powder and mix it with oliveoil. your welcome :)

[P4r4k]

@qazman4 WOLVERINE TIME *o*

[83gta]

How to get it, wath's the price ? it''s amazing !

[Dvermoet]

will i become venom if i touch? :)

[iteattachment93]

from the preview it looked like a dildo.

[pcrana1]

o.O can u buy that liquid?

[despicableBri]

Ok so where is the how to video? I somehow saw how to make slim and 'Obleck' but can't find how to make liquid awesome.

[kylechandler4665]

it's like spiderman's evil suit

[RonaldR2007]

This substance is cancerogenous for sure. Don't play with it.

[kyle3420]

@RonaldR2007 how do you figure?

[RonaldR2007]

@kyle3420 Any substance containing micro metal particles is potentially cancerogenous. You need a lab and proper security conditions to "play" with this.

[kyle3420]

@RonaldR2007 you mean carcinogenic?

[howycwap]

@RonaldR2007

its just itron in oil. theres no isotopes or anything radioactive emitting from this. no fumes or anything.

[RonaldR2007]

@howycwap It doesn't need to be radioactive to produce cancer.

[howycwap]

@RonaldR2007

i know thats not all i said.no poisonous fumes. mercury for example is carcinogenic. but iron is not. and thats all there is in this

[RonaldR2007]

@howycwap All these metal particles are potentially cancerogenous.

[howycwap]

@RonaldR2007

so iron ore can give you cancer, or an iron bar?

[AwesomeFilms101]

Can you Re-Use the ferrofluid?

[Samuelfindlay]

Thanks vsauce.

Also: It looks like that screw is turning into venom. 0_0

[chukaz1]

i think mechanics who work with oil, metal, magents and electricity would've seen this effect once or twise i would say.

[earthyearth]

why does it have a spiky shape?

[gabriell16bishop]

that screw looks infected!

[haristoteless]

wuao es increible no conocia nada sobre esto



[heavymigration]

ALIEN DICK!

[piggyfreak06]

That's the venom that corrupted spiderman!

[steppachshit]

the new generation of dildos ....

[isurfu2ube]

so what does good come out of this fluid in the future?

[smelldis1luv]

thumbs up number 4 LOL ! ! !

[haloguy09]

thumbs up if you thought that was a dildo

[ibetrolintomuch]

@haloguy09 thumbs up if u think thats a stupid ass coment

[haloguy09]

@ibetrolintomuch thumbs up if you know this niggas gay.

[GandaGree]

@haloguy09 i thumb u all down

[Skiddla]

@haloguy09 i totally expected this to be top comment already

[Worgenftw]

Dude I want to play with this so much right now, lol.

[killeroid07]

Is this ferrofluid toxic ?

Where can be bought ?

Thanx in advance ! ! ! !

[hartiserver]

ferrofluid : iron powder and oil mix and you can control with magnet :)

[hendosia]

this can be used for a donut antigrave unit.

[123stebow]

does the liquid solidify?

[chucknorris974]

i wonder if humans will ever make a machine that saps magnetic energy from magnetic objects and pulses them into humans

then i could attract ferrofluid and use it as armor

[mislovelyest1]

hmmm..... Interesting....

[22mar79]

Alien technology.

[sirmenonot]

You can do that with printer toner.

[nicothegreat795]

please explain what ferrofluid is and what is it used for.

[Oozblar]

What are some practical uses for ferrofluid?

[grim442200]

@Oozblar it can also be used to create a air tight seal on spining gears and axles

[charliehockey78]

All I can think of is megatron's penis...

[lekovic199]

but will it bend?

[imawakeish]

sorry but what is the point of this?

[dragoninfire123]

@imawakeish to show you what is ferro fluid...

[imawakeish]

@dragoninfire123 good answer but i mean the actual liquid ... does it serve a purpose?

[dragoninfire123]

@imawakeish lol, umm... well, liquid seals around spinning drive shafts in hard disks, friction-reducing, cancer detection... just go on wikiperdia ;)

[imawakeish]

@dragoninfire123 yeah actually that was quite a dumb question.... cheers

[mrsk8rpunk666]

and thus...venom was born



[LionsOfTheSafari]

It's freaking VENOM! Help! Spider-man!

[karkovice10]

That's amazing!

Is that fluid you're working with in anyway toxic?

How do you clean it up afterwards?

[spcutler]

@karkovice10 You wouldn't want to eat it, but it's not toxic like, say, mercury. Soap and water generally suffice for cleanup, but if you get it on anything absorbant (clothing, wood, etc.) it's *never* coming out. It even takes a while to come off your skin.

[Ilovelazers]

@spcutler so wht exactly IS this?

[guikgfzjr7]

@spcutler just like oil

[IWasBornStupid]

@spcutler Is it safe to poke Ferrofluid with your finger!? :D

[davidbourne1]

@spcutler what if you use a magnet to take it off your clothing or skin?

[northtreker2003]

would you be willing to give us the chemical formula for the fluid?

[MatchBoy117]

@northtreker2003 Oil, iron (II) or (III) oxide, and some stuff that keeps the iron oxide from falling out

[spcutler]

@MatchBoy117 That's basically right--you need a surfactant to keep the iron particles (magnetite, specifically) to stay suspended.

I tried making some myself using oleic acid as the surfactant, but it honestly worked quite poorly. I believe the problem was with the particles themselves--too contaminated, and the wrong size.

[goco789489]

i...want...a....magnet....now.­..

[DaModernKnight]

looks like a super dildo

[gabin1colas]

from spawn's suit...

[elitechalenger]

how do i get this stuff

[rictorven]

Magnet puddy

[KidShanobi1]

Wow freaky stuff!



[presbarkeep]

will it blend?

[thedemonslayer51]

@presbarkeep no. It is a liquid, like water, so it will not blend.

[presbarkeep]

@thedemonslayer51 so youre saying i could put it in a blender with some ice and make a smoothie out of it?

[thedemonslayer51]

@presbarkeep maybe, but that would probaly be a bit hazardous, or poisonous.

[jiijaa]

VENON IS HERE!! OMG

[doggiesteigger]

Where do they sell this shit???

[Techible]

@doggiesteigger "ferrofluid" on google

[ActivityPoltergeist]

and this shit is fucking real?!

[NBAPwns13]

how did you do this ? can you explain in steps?

[malletbjm]

alright enough already, where do I get some.

[kittygal92]

what is ferrofluid?

[XZeldaLoverX]

I want one

[DHyunC]

I found one of those thingies.. in my moms bedroom drawer

[GWmaximus]

still dont get it

[Ir77iridium]

I was an engineer at Ferrofluidics until the company went under. We used ferrofluid for seals on feed-throughs for vapor deposition chambers, acoustical speakers and damping on nuclear subs. We had another division that build crystal pullers and used ferrofluidic seals around the crucibles.

[mark01318]

is there any use for ferro fluid other then making youtube videos ?

[seapeddler]

A remake of the classic " Screwge".

[Creslin69]

Hey, how big was the neodymium magnet you used? I just bought a small set of 1/4x1/4x1 inch bars to experiment with, i'll prolly make a variable electromagnet one of these days too.

[bashfulrose12]

This is awesome!!!

[DrinkUrPruneJuice88]

Where do I get that bolt

[DrinkUrPruneJuice88]

Where can I find a magnet shaped lik a screw? already got my ferrofluid ready though

[UrsidaeFilms]

@DrinkUrPruneJuice88 The screw is not the magnet. It states in the description that there is a neodynium magnet beneath the screw.

[KillerRadar]

that stuff is gonna take over the planet some day

[okami912]

but will it blend?

[IDGIPro]

DID YOU MAKE THIS YOURSELF????????

[IDGIPro]

DID YOU MAKE THIS YOURSELF!!!!!!!!!!!!

[Cardossian]

@neal12rh:  Thanks!

[Cardossian]

Why the little spikes?

[neal12rh]

@Cardossian The magnet is pulling on the fluid while the fluid is pulling on the magnet. its a push-pull relationship and the surface tension in the liquid causes the peaks to come to a point

[Hassassin1990]

Hi, why did the ferrofluid stay on the tip of the bolt? How did you position the neodynium magnet to do this?

[spcutler]

@Hassassin1990 The magnet is stuck to the bottom of the screw, on the other side of the plastic bowl (so as not to contaminate the magnet).

The ferrofluid sticks to the top because sharp edges and points concentrate the magnetic field, and so the fluid is attracted to those parts. However, if I add enough of it, gravity overcomes the magnetic field and pulls the fluid down. You can see that by the end the fluid starts pooling at the bottom of the bowl.

[Helge129]

@spcutler The "spikes" in the ferrofluid I assume are where the magnetic field lines leave the screw, right?

[spcutler]

@Helge129 Sort of--magnetic field lines aren't "real" but the spikes do indeed match the direction of the field.

The spikes themselves are a balance between two forces: the magnetic field, which tries to stretch them out and separate them (like how two bar magnets placed north-to-north will fly apart); and surface tension, which tries to smooth things out. The spikes get... spikier... as the field strength goes up.

[good4ud]

@davdayha its not sharp at all you can touch it and its like water , exept its really messy

[csmasta07]

my AP art class was required to create a piece of art this semester using ferrofluid.(which is the name of this magnetic fluid you are seeing here.) I made a website for the class with videos and photos of all our projects. - ferrofluids.info

Any feedback is greatly appreciated, thank you

[Klaasje26]

WoW! i saw this @ hackaday.com  verry nice!

[qwertydogson]

Is that real? How does it work?

[g0rbak]

if i saw it i would want to touch it so badly ^^

[justtorate13]

@g0rbak

thats what she said

[BinaryCommando]

Thanks! Just got some and was trying to do exactly that but couldn't figure it out....

[3Qstm]

you guys are all noobs even a child knows how to make ferrofluid :/ hahaha

[InwardChaos93]

This kinda looks like the stuff they used for Venom in Spiderman 2. Or was it 3? I cannot remember.

[gekolvr0734]

that... is so cool.

[dafrandle]

that is so cool

[gaylordman123]

coooool

[redhotminipepper]

Me and a friend have decided to do a ver important project in school about this stuff. Have you got any suggestion about what to research with/about ferrofluid?

[megakid39]

Where does one get this?!?

[blueeyesseto]

@megakid39 make it

[megakid39]

@blueeyesseto How?

[awdrgy123]

did you make this yourself or did you buy it?

[spcutler]

@awdrgy123

I tried making it, but had little success. It's very difficult to get the iron nanoparticles just the right size, and I don't have the right chemistry equipment to do it right.

Instead, I bought it from "Educational Innovations, Inc.". I am not affiliated with them, but am happy with their product.

It's not cheap, unfortunately.

[morenofreire]

hey can you tell me what kind of ferrofluid did you exactly use? I have two kinds of ferrofluid yet one of them is too viscous and the other one is not viscous enough.

[spcutler]

@morenofreire I purchased it from Educational Innovations, Inc. It's not very viscous at all--like a light oil.

[morenofreire]

Hey man... I was sure you prolly bought it from there.

I have some ferrofluid ( actually I have a shit load) that I found in my lab. I want to make it less viscous by adding some solvent yet I need to know the exact viscocity of the same. Do you think you can provide the info?

[spcutler]

@morenofreire To be honest, I don't have that information. However, if I get a chance I'll do a bearing-drop experiment to compare against water. It won't be very accurate but it should be close enough for your purposes.

[TheFirstLiquidVideos]

@morenofreire try mixing them up xD it wont explode or anything xD >_> i think xD

[cumesoftware]

WOW! No wonder that ferrofluid is used to seal motor bearings. Amazing!

[lalalandtrombone]

where do you buy it and dose it come with a little kit and uhhh will it spiol?

[FlamingHippoFilms]

For some reason the result from the end of the video reminded me of Aliens...

[hjustin93]

Can I buy this stuff??

[PITsteelers93]

Where did you get the magnet and how much was it?

[12ragoschkema]

-wants to touch fluid SO BAD-

[Blayros]

I got an idea...... put this shit in the oil we ship around the globe and when we got a spill in the water we just put a giant electro magnet into it and pick it up.....???

[Bowfinger6383]

@Blayros that's is a good idea. but probably to expensive to make to be practical, sad that the environment always has to pay for our being cheap. When the BP spill was going on,I thought they were doing it wrong,by breaking up the oil,instead of trying to make it thicker, like turning it into a big tarball.

[ryan50ryan]

that is freakin' cool.

[spoman818]

i want ferrofluid!!!!!!!!!!!!!!!!



[Gazzness]

@spoman818 you can make it.. MICR toner and vegetable oil xD

[lordofgangstas]

Lol,doesn't it look to CGI-ish to be true?I know it's not and that makes me hapy.THUMBS UP IF YOU AGREE!

[TETOYVIENDO]

HELLO, how much cost a liter or galon of this "ferrofluid"??? and where can ppl buy it??? thanks...

[ARJHaloRadio]

WHAT IS IT

[turbotonic27]

where can i buy that ferrofluid?

[coutof002]

i wanna eat it then swallow a magnet =3

ill see what happens

...... FOR SCIENCE !!!!!!!!!!!

[DarkCybrid]

That is so neat

[zheyy]

hahaha i read it wrong, i saw terror-fluids ;P

[KoreaHatesYou]

it looks cooler if the ferro fluid starts at the bottom of the screw :)

[wolffe23]

if u touch it will it hurt?

[EpicNinja123]

No. It's basically oil and toner. It's not good to drink, but perfectly fine to touch as long as you wash your hands aftwerwards.

[markyyyyyyyy321]

Where can u get ff from?

[wtfdinges]

you can make it yourself by mixing laserprinter toner with oil (not all toner works, it has to be MICR)

[TOXIKKOBK]

yay for magnetics and flux lines

[hellzBrother]

Very cool. Nice video :D

[InSaneTK]

Gotta love physics, and ferrofluid.

[Gregorius144]

Jesus christ! Where did you find a screw that size?

[max16]

@Gregorius144

its a small screw. -_-

[wowii1234]

@Gregorius144 lol its a normal screw that u use for ure freaking cabinets

[wtfdinges]

@Gregorius144 its just zoomed in :P

[markyyyyyyyy321]

u idiot

[Wowblogger]

this is awesome im gunna go get some toner tomorrow

[Joonas323]

no its not.

[fmatano]

this video is backward isn't is?

[randomtricksvideos]

no you need to understand science more

[hunterdanjones]

it dont even look like its backwards

[Soda233]

o i get what he is saying the fluid is usually on the bottom and travels upward and this one he puts it on top and goes down

[lux551]

it looks like a drill...cool!

[Chivopuro]

WITCHCRAFT!!!11!

[Thatfatguyfrommars]

one

[QuantumRise]

eleven

[8182junebug]

symbiote goo. run for your lives!!! lol p.s. this stuff is awesome!!

[Gamethroughs]

i just came from a video with people using bells and it starts moving
