Simple Magnetohydrodynamic Motor

[greatidea11]

Excellent experiment

[JUANITO2859]

now the best of all is you light a lighter to it and will have a nice explosion !!

[f0ckt]

Is that enamel coated magnet wire or just straight up copper?

[MrJamesbusy]

those long words

[johnboy75757]

Eww, you're a girl!!

[santiago6468]

valen vergan suban un video a you tuve que valga la pena

[DolleLovez]

now i dont need to stir my chocolate milk :D

[hollymanhollyman]

AHHH!! that how UFO work!!!

[pearcorn]

I used the name as a tongue twister for my friends :)

[animewatcher5]

You're a nerd.

[sergo40]

This is cool...*reads comments* wtf..some ppl rlly think AA batteryes can electricute you? >.<

[520canon]

this should actually electricute you if the current goes into the metal rods to go into the peppered water

[TABAGfrancis]

Please watch:

[definitionofis]

Is the process reversible ? Can I generate electricity across a tube by flowing salt water in it ?

[oskay]

@definitionofis I believe so.

[x65535x]

@definitionofis

Unfortunately not, although the ions are moving, it's due to the voltage potential across the liquid and the magnetic field created by the flowing current that causes the ions and the water carrying them to move.

When you move water across bare leads attached to a load, the net charge stays zero do the the homogenous nature of the liquid containing the ions.

[OfficialHeadShotKO]

Would this be caused from an ionisation of the solution? (Where the cathodes and anodes break the bonds in the molecules)

[usethisaccount4video]

@usename80  It says at the beginning, it's water, salt, and pepper

[usename80]

what are the ingredients of the cup

[kejhmaster]

whast so mad sciency about that well any way i know how that works :D

and you retards dont! LOL and thats the truth and no one answer me or else your a homo

[OfficialHeadShotKO]

@kejhmaster

WEIRDO WEIRDO WEIRDO OMG OMG A WEIRDO!!!!!!!!!!!!!

[inemanja]

@kejhmaster u dont know a shit... :N

[sperooo]

thats because when you pass a current through a wire .. it generates magnetic field around it and you use right handed screw rule to determine the direction of the field

[ugluvztrance]

Pepper for flow visualization, I'm guessing. That's cute. Nice work.

[Cambodianskater]

thats cool, but what could make it useful?

[itsme4880plus]

mmm I see..

[smeard1190]

how does this work>?????

[oskay]

>how does this work>?????

Maybe you should follow the link, where we discuss that.

[RyuDarragh]

@smeard1190: Salt water is slightly conductive. An electrical current flowing through a conductor generates a magnetic field. A magnetic field induces an electrical field in a conductor (causes an electric current to flow). Rinse, lather, repeat. The water is responding to the electrical and magnetic field of itself. See the movie "The Hunt for Red October" for a good notion of what it could be used for (I love hard science fiction ^.^)

[smeard1190]

how does this experiment work>?? someone answer me please.......

[thesparitan]

its the hunt red october

[steveincairo]

Fun in the sun.

[KrazyAnub1s]

Making poison? haha

[drguerau]

I don't think you need pepper for it to work though.

[Jedi2155]

It's just to let you see the direction of the current.

[jacker372]

its to see it move not for it to work

[steveincairo]

The pepper is probably just to make the flow visible, kinda like bringing iron shavings near a magnet.

[poojoojoo]

I think it was just used to accent the water spinning.

[oobernerd]

ahahah i like the way he says its a "simple" Magnetohydrodynamic Motor. lol not so simple name

[bjornwitteman]

whats happend on 0:26 in de cup?

a flash??

[PyroFreakDJ]

Light, reflection.

[dsavetark]

no its just reflection

[KKinsane2009]

electricity.

and the actually reason they don't let you put dc through water is that it splits that too, into fuel, which we we're told is not possible, lol.

its something to do with more electrons from a physics point of veiw, but yea im seriously, this does make chlorine, use baking soda as recomended by other videos.

the sodium seams to bubble on the nodes and fuse to the metal slightly, while the chlorine bubbles away from the metal out of the water toward air. smells nasty and metalic.

[KKinsane2009]

salt = sodium chloride = sodium + chlorine

you sir are the faggot here.

[hellstudios]

Fuck. now you got my curiosity glands going. how the fuck do you split salt into it's components?

[matthewm0311]

lol

[EarthsGravitySucks]

nothing like mixing sex, religion, and politics in with a little chemistry.

[graffdude1234]

hey can anyone tell me where to get copper wires? think and thin, please comment back.

[damnedboner]

Yeah, go to any junction box in your house shut off the breaker,, yank out any wires you see.Cut them. DONE.

[whitetaildave]

hardware store or electronics shop....what size?? goes from 40gauge(smallest in diameter) to 0000(biggest in diameter)....you might not be able to get over 8 gauge(as in bigger diameter)

[governmentcheese411]

interesting,but still a waste of time. stop wasting time with shit that wont help and focus on the things that WILL set us free.HYDROTHERMAL is the answer. literally nothing better,nothing safer,nothing more efficient, and nothing more abundant to answer all of the worlds energy needs,period.

[KKinsane2009]

I think im wrong about it being browns gas, i think its sodium and chlorine, I can't find what I thought it was on google.

[cocopops149]

chlorine is much more poisonus that brown gas

i think

[KKinsane2009]

just did this with a larger tub, it works, the spin is visible and I have a video on a phone, BUT thank you for not mentioning that it creates browns gas, now I feel dizzy and really stupid. (you fucking asshole...seriously there is no warning here...)

the wires on mine were copper attatched to magnetic croc clips of some sort, one stuck to where the magnet is under the tub, one taped to the far side away from magnetic pull to prevent disaster.

again, this will create BROWNS GAS which is TOXIC

[hellstudios]

how in the fuck can salt, pepper and water create something toxic you fag. xD

[StonedBC]

ITS THE RED OCTOBER! LOL

[psychodelicdragon]

thats cool as i dont know what!!!!

[allevian]

Cool- I´m gonna power my rc-plane with it.

[zker666]

thats a big word right there... put that in front of a kid in a spelling bee!

[ZeldaItachi]

This reminds me of electrolysis....Is that what is occuring here or is there something different?

[pyropc10]

This is totally different from electrolysis, one because water doesn't move in electrolysis and two because there are no bubbles forming. This is occurring because of the motor principle and the conductance of salt water. As the current flows across the water in the presence of the magnet under the cup, the conductor (the salt water) is forced to move in a direction perpinducular to the direction of the current and the external magnetic field, which causes the water to move.

[dddiiiooonnn]

pretty cool!!

can u specify please how much water, salt and pepper did u use?

[Ne3bO]

all of those elements arent critical, just put random amounts in and it will work

[nallenito]

Doesn't sounds simple...

[Luke13PL]

its copper a battery and that water w/ salt/pepper......

[ElectronicSculptures]

If you figure a way to speed it up, you can have a high tech cocktail stirrer.

[mrspokito]

i did it and only get bubbles from the redox reaction between the coper and the ions. Why?

[phaub]

mrspokito, you probably forgot the magnet...

[mrspokito]

no, i used a powerful Neodymium magnet that, if sumerged, cant stay stand up because the atraction of the metalic inner structure of the concret shelf.

[bernakitty]

isn't the magnet supposed to be UNDER the bowl??

[yyyzzzz]

read what it says on the screen!

[2BSilveR]

whos girly hands are those?

[souljasai]

oskay's xD

[reluctantprophet7]

I remember my teacher in Physical Science liked ta blow things up. One day he had a milk carton rigged with 2 nails on either side making a small gap in the middle.... then he added "just a little" rubbing alcohol and corked the jug. of course when he aded the electric currnet, it shot the cork wit ha pop. First off, it shot a classmate in the head. And then he realizedd there wsa too much alcohol when the jug (and consiquently a spot on his desk) caught fire.... it was grand....

[gatention]

uuuuuuu........uuuuuuuuu

[txroyscock]

Pretty cool

[moni370]

lol ima connect like 10 D batteries together and make it spin super fast

[larueferguson]

Finally a easy way to stir my coffee!

[skierplaterandy]

lol. you would need much more current

[kefsound]

...and it will also get warmer if it wasn't hot enough.

[debrouillard123456]

You like you coffee salty?

[dickofdead]

coffee is a big shit...he's like cocaine!

[bilzoo2000]

since you have the proper seasonings, after a while the heat generated from the current through the water will warm you up a nice soup.

[TheLangfords]

Never mind "clockwise" and "anti-clockwise", what about "turnwise" and "widdershins"?

[robrancid]

no .. its all about Slitherin and Gryffindore

[Daisubu]

lol

[KelseyMFStalker]

naw dudes its hgujdmdksidm & jsjiwssiwlaoajsn thats what we say in ghnshbdstvfgajnb8diwe!

[bradsommers]

Yep, we Americans say counter-clockwise, not anti-clockwise.

[luis11fer94]

[puckcreep]

¿Por qué diablos no importa

for all wonering i said why the hell does it matter

[BIasphemy]

aprendan a hablar...

[bestSVMS]

i dont think the magnent does anything

[TheLangfords]

Without the magnet, the water wouldn't move. Try it and see.

[BowHunt1229]

why?

[gvcam09]

does the pepper effect it or is that so you can see the current?

[oskay]

>does the pepper effect it or is that so you can see the current?

It's just for so you can see the water move. :)

[RyuDarragh]

And I hope no one thought the tech in "The Search for Red October" was sci-fi :D

[Xxero0]

if its so simple, why cant i pronounce it?

[enyceckk101]

TO XXERO0

if its so simple, why cant i pronounce it?

Cause u need more education

[Xxero0]

honestly, im ahead of my class (9th grade) and my brain works at college level. i cant pronounce it right off the back, but after a few minutes of glancing at it i can. try pronouncing this:

pnumonicultramicroscopicsilico­volcaniconiosis

and now give me the deffinition.

[enyceckk101]

hmm thats a term when people mine .. and they get black lungs

[Xxero0]

close. its the black lung disease. not just, they get black lungs. but hey, most people would look at that and say, "fuck you." so, ya. =)

[enyceckk101]

hahah

[Xxero0]

btw, how old are you? and do you have any college degrees? cause im actually very suprised that you knew the definition to that. theres like a 1 in 10000 chance of that.

[enyceckk101]

im in college right now ( 2nd year )

In New york

[TrickyHank]

nice

[anarki2004]

yeah, I know this is from like a year ago...w/e. pneumonoultramicroscopicsilico­volcanoconiosis is really not that obscure of a word. Neither is antidisestablishmentarianism..­.and for that matter floccinaucinihilipilification. Just big words people toss around to create the illusion of intelligence. Its great that you're smart and what have you, but your post here makes you sound like a jackass.

[howisdiscool]

so if i used a car battery..?

[JakeManes]

WHy doesnt everyone just go to the website instead of blabbering about total bullshit, and making yourself look stupid?

[supersandor]

Wow, I didn't know the forces were strong enough to swirl liquid from electrolysis like that! Or is it just a really strong magnet? Now that I think about it, that does seem about right. If the magnetic field lines were up and down, with the two electrodes front and back, the force is of course perpendicular to the both of them, which makes it go left or right between the terminals, which makes it swirl around them. Great way to stir the coffee if you don't mind getting 20000% USRDA of copper...

[willifton]

it has to do with the diamagnetic properties of water?

[phxfreddy]

Its the current flow through the water in the presence of a magnetic field.

[CiReReBoT1928]

that was weird...

[super1commenter]

i tried it, it dosen't work

[ChazWeisbeck]

did u put a magnet under the dish??

[super1commenter]

duh

[ChazWeisbeck]

wierd

[blkwlf0]

did the battery work? did you really use a magnet and not a round peice of metal? washer*ahem*?

[super1commenter]

it is a magnet

[mmpalha]

does that work with any liquid?

[chadtobias]

the water has to have some kind of electrolyte, like salt.

[mmpalha]

thanks!!

[Mindcrime121]

I love these vids. They are simple and should get kids interested in science and physics. Beats the HELL out of the droaning and text book crap in schools.

[Starcross42]

I teach physics in a school and I couldn't agree more!

[808moparskate]

you are right it is very boring in school but if they were to do this like this it mike acually be fun

[pituzofi]

u r so fucking right... if I had been introduced to science this way i would be a lot more interested in it than i am now

[ShadowWhiteHawk]

Instead of starting off with studying cientist's work and blah blah blah, every class should start with something along the lines of this:

"BEHOLD CHILDREN, THE POWER OF PHYSICS!"

*performs some awesome experiment*

Then children get all jumpy asking "HOW DID YOU DO THAT!?!?" and you teach away!

[skierplaterandy]

ahh i wish my teacher would do that shit...

[crispexi]

My high school science teachers did that. They would make a fireball or something to that effect the first week of classes.

[addmoreice]

my chem teacher walked into class while everyone was talking popped open a container of a high solution of hydrogen peroxide then walked out...and the smoke POURING out freaked some kids out. it was cool.

[MyDogSnorez]

dude, i want my teacher to do that. shes making us build strucktures that can stand a "earthquake" (shakey table thing) and it is made out of marshmallows and unkooked spaghetti. it is BORING! watching my cat chase its tail is more amusing. (and i know it already is)

[sneakynessss]

This is what teaching should be like, but isn't.

If that doesn't impress a child, then that child is broken, and should not exist.

[irontoad123]

Does the water spin anti clockwise in Southern hemisphere?

its easy for me to find out

post your answer

[havemercybabe]

it has NOTHING to do with where u r.

yr 9 physics....electromagnetic fields.

[arthur15091990]

no, it mostly depends on sink shape.

[retrogamer500]

The Coriolis effect has nothing to do with it. And I have been to the southern hemisphere, toilets spin the same way. The Coriolis effect is minimal! A cyclone is more than 1,000 km in diameter and lasts for more than a week. Your toilet is less than a meter and drains in a few seconds. Arthur is right, it is the shape of the sink/toilet that affects the direction of rotation.

[TooManySnakes]

And if they don't believe that, tell em mythbusters busted it.

It's certainly easier to just calculate the behavior as a Lorentz force problem in this case.

[Tutchmydog]

lol look at the big picture and you can create larger more helpful device gj.

[Ninja9191]

The proces is: electrolism, you can clean water with that :P

dude science fair is in a month what should i do with magnetism

?

[oskay]

>dude science fair is in a month

Only a month and you haven't picked a topic yet?

[joaqsangar]

i mean i have one but i dont know if we can do it so i have to have a back up what should i do?

[Dragonfire7666]

Through electrolosis the water also contains copper sulfate. Just passing knowledge, I flip burgers for a living.

[blahdob]

cool! i never knew that would happen.

[pimpachu]

What happens if electrodes are put in sideways- as in insulated at entry point then bent; Would we see linear surface flow?

[oskay]

The flow is only circular because of the shape of the vessel-- you can certainly make linear flow a few different ways.

[pimpachu]

I meant something more like... if one electrode was placed high and another placed low; parallel to the ground in a way that wouldn't allow interaction of the parts of the wire that are perpendicular to the ground with the water. What would happen then?

[joliteal]

This shold be teached at schools! It is not too complex, and it is amazing.

[drainoftheage369]

Not teached, taught. Had to point that out :)
