Lava Lamp in a Centrifuge

[sAcRoSaNct17]

It looks even cooler 0_o

[TheZombieLibrarian]

That's a hell of an erector set.

[Monstoday]

I'm interested in measuring the G force on roller coasters and fairground rides. What type of phone and what phone app were you using?

[blakereed92]

43 seconds in... WE GET IT, YOU BUILT SOMETHING COMPLICATED!

SHOW THE SPINNING ALREADY!!!

[HUGOVANTA]

lets just casually build a centrifuge in the middle of your living room.. nice!! good effort (Y)

[CatalinaThePirate]

This rawks!  XD

[clouseinthehouseee]

Someone has alot of time on their hands! Good job!

[TommtheDrummer]

Very cool :D

[PumpManufacturers]

nice show

[2MeterBONG]

Meccano rulez!

[polarstar75]

Im AMAZED.. how long did it take you to build this thing??!!

[phil538]

haha, thats fantastic!

I hope you were standing well back and wearing a lab coat for that.

oh, and for rescuing that guy from jail, I take may hat off to you sir.

[toejam1200]

What we got here Mr Scientist !

[chicomilo]

What the Hell is that. You have way too much time on your hands. You built an erector set centrifuge to spin a lava lamp to see what it would do. That is totally useless. You are my hero! I love IT! Im subscribing

[BloodprinceDC]

Did u say made of meccano?

[xboxhackingportal]

Thank you for letting me know that I do NOT have too much free time on my hands. LOL

I'd love to have half of that free-time you have.

[skipplet]

1:16 Coriolis effect?

[Odo987]

@skipplet Not quite. Early in the spin cycle while the centrifuge is still accelerating the counter-clockwise rotation is just momentum (liquid wants to be a rest, but lamp is being spun). However this damps out soon after a stable 3G is reached. Then at the end of the video the liquid starts a weak clockwise rotation. This is the Coriolis effect!

[HCNguyen86]

Nice project!

[MrPoof15]

what did you make this out of? i wanna buy the kit so i can build my centrifuge electrification generator

[themadscientest]

gave ma a boner in the awsumness of that thingy

[element2310]

Thats an insane use of mechano, but nicely presented well done!

[DigitalEchoFox]

Cool. I think you should do it at night, with the lights off.

[dariuslloyd]

Nice job. What is the song??

[ponkkaa]

#1 Great video and sweet piece of engineering.

#2 YOU HAVE WAY TOO MUCH FREE TIME.

Well done.

[quasarinstruments]

Very nice video. Impressive work building the centrifuge.

[xenonmorph5]

the nexus can show u gravity force??? awesomeeeee!!!!!

[espasimo]

It's not entirely accurate, as the wind from swinging around would cool off the "lava" making it work better.

[Odo987]

@espasimo In practice it takes two hours for the lava lamp to warm up to its circulating state, so it has massive thermal capacitance. I doubt that 60 seconds of wind would have much of an effect. But your point is valid.

[skate2spellgirl]

I don't want to go to Jupiter

[danimal511]

seems like a lot of work.

[GiovanniC91]

Looks like a Lava Lamp on Jupiter is BADASS!

[Jazza159]

dude thats allot of meccano!!! Awesome though

[RoboTekno]

Erector Set! XD

[Leviathan2k]

This is something one normally would only see on Mythbusters. Awesome.

[aadamm]

lava lamps are a lot cooler on Jupiter!

[Zeppo3]

It's things like these that show the human ingenuity and perseverance to find out things that makes humans Great!

[jocax188723]

you, sir, are awesome.

[jthmdomestic]

What the hell is this song? I want it.

[sebek23b]

As you can see it will work if it does not freeze at - 152k.

[rcarvell]

Sir, I salute you.

[bakerman4444]

haha...awesome!

[horrgakx]

In any gravity it will still behave this way because the forces are equal on all of the liquid inside it.

[rincewind1966]

Nice use of the Nexus One there! I award you the prize for most perilous place to put an N1

[TimbergoSpielbergo]

Why would gravity affect the operations of a lava lamp? Everyone knows that the force of gravity acts equally regardless of mass.

[avgurim]

@TimbergoSpielbergo

I think you turned the issue upside down...

The MASS hasn't changed. The GRAVITY "changed" (temporarily).

And so the WEIGHT of the same MASS (lava lamp) increase for the duration of the circular travel.

[Gh0sty]

The answer is no a lava lamp wont work on Jupiter as there is no where to plug it in. Kewl experiment though!!!

[LuminoHSR]

no explosion -.- :D

[htnhrd]

it's just fluid's mechanics come'on!

[Ganiscol]

And the living room also survived! Excellent!

[TheMawnkey]

I love you, Internet. I love you so much. :-D

[schoschie]

You, sir, are crazy. Great :)

[mrlazy187killa]

damn that wuz clever

[Sqrrl101]

So, you were curious about something and decided to build an extremely dangerous-looking device to test it experimentally?

You have my admiration, sir.

[BattlingTube]

This video has been entered into the 'Top 10 Technology Videos of the Week' battle at BattlingTube website.

[RuudJH]

OMG it forms the image of Satan eating a donut!!

Amazing.

[ShadowUMP]

soooo no?

[Pitviper70]

Yes it will. The rotation of the centrifuge induces eddys in the oil that are disturbing the flow. But generally, you can see up and down motion of the wax.

[bluebalute]

What a cool geeky experiment. I liked the view of the camera viewing the room as the centrifuge turned and a very nice touch was having the app. show the G-force.

[RiddickTheKiller]

Nice experiment.

Riverdance? LMAO

[skittle68]

So was this an experiment for a college class or something? Or just for fun?

[wease1]

You're applying the gravitational field from the side, not the bottom. This experiment is not exactly valid.

[qed100]

Consider this: If the force were toward the Lamp's side, how would you expect the lava to behave? I'd expect it to flow to the Lamp's side and form a puddle. But the puddle was right where it always is, in the Lamp's base.

It means the force wasn't toward the side. It was to the Lamp's base at all times, even at high RPM. To see why, read some more posts.

[StinkFingerr]

Hey, looks like my old erector set!

[dextor123]

simply amazing, nice meccano work, thx for this

[skittle68]

Having the lava lamp standing upright means the the exta force simulating the gravity is applied to the SIDE of the lave lamp. So this simulates whether a lava lamp would work on Jupiter, laying on its side. Hmm. You would think the people who were smart enough to build this contraption (which I for one, could not) would be able to figure that out.  Unfortunately, if it were on its side like it should be the heat that makes the lava lamp work wouln't be aimed right. Lose:Lose :(

[Odo987]

As can be seen in the video, the payload container swings outwards automatically so that the lamp is always correctly pointed 'down'.

[DracoAleksander]

I guess you didn't notice that the capsule containing the lava lamp is on a rotating axis, so it adjusts its relative "down" to wherever the largest force is. No problem, though, since you already said machines aren't your forte.

[qed100]

@skittle68

Two things:

[1]- Your complaint has been discussed already in this thread. Read and learn.

[2]- If you don't know how to read, then watch the video more carefully. The Lamp is in a hinged cradle. Lose.

[whisper4132]

@skittle68

The lava lamp is on a swivel, so that it's bottom is always pointed to where the greatest acceleration. You should have picked that up from the camera shots that gradually turned as they sped up. FAIL

[FluxTheorem]

@skittle68 lol you are dumb

[skittle68]

I guess I didn't look far enough down in the comments to where this was addressed, and I've looked closely at the video a few times now, and it's pretty hard to tell the lava lamp is on a swivel axis. That makes this experiment much cooler though.

[dravidr007]

@skittle68 idiot

[Tamponfeast666]

@skittle68 shut the fuck up. this vid is about animal porn

[geomonicdotorg]

@skittle68 Actually, buoyancy acts in the direction of acceleration, so for centripetal force applied from the centrifuge to simulate increased gravity, the bottom base of the lamp should be faced outward, not inward, or on its side, with the top of the lamp aimed inward, directly toward the axis of rotation. The lamp as a whole will still respond to the force of gravity acting on its side, but negligibly when compared to the 6 or 7 g's felt opposite the axis of rotation.

[Digeridude]

I award this no less than five sciences.

[slackpad]

Well done, sir!

[choreforthelost]

FOR SCIENCE!

[JNish]

Or you could have just figured out that lava lamps work based on different densities of water and wax and gravity doesn't affect density... Nice contraption though, I would have been worried it would become unbalanced and smash into your bookcase.

[qed100]

@JNish

In this demo the value of g plays almost no role in the density of the water. But g does determine how the fluid pressure changes with depth, and therefore the buoyant force that generates convection. Consider the lava lamp falling freely, weightless. There's no pressure differential and no buoyancy. The lamp doesn't do anything. As it turns out, gravity does makes a difference. Jupiter's stronger surface gravity enhances the lava-ness of the lamp.

[choreforthelost]

@JNish With something as complicated and as intricate as this, plus his clear knowledge of electronics and basic physics, I'm fairly certain the guy took weight differences into account...

[mrblifil]

@JNish wyagoddabeeyahata?

[elpppa]

Umm.. Where's the lava lamp's power cord?

[qed100]

@elpppa

On Odo987's website he explains that the Lamp is wired into a standard cylindrical, 1/4-inch-diameter audio plug. The plug stands vertically in the middle of the machine, and its cylindrical shape allows it to swivel within a cylindrical power connector that's plugged into the wall.

[mcforge]

brilliant experiment

oh, and, everybody get a N1, it makes a great G meter :))

[svandamme76]

probably better to measure the G forces by using a calibrated spring, and a fixed weight...

[karansb]

niceee one man this is definitely FTW!!!!!!!!!!!!

[rodylermglez]

This is a crazy idea... AND I APPLAUD IT! 8D

[Hemulen40]

& then pls put it in  da micro oven . ( :

[502502]

advertising for the phone...

[MrTurdburgler1088]

@502502 shut up steve jobs!

[MrTurdburgler1088]

ok whip it out.

[thearaban]

looks fun

[silkyjueves]

thats so sick its made out of an erector set!

[metaldragon680]

Wouldn't it make more sense if the lava lamp was parallel to the floor instead of being vertical? I would imagine that it being vertical the extra g-force put on the lamp would be put on the side of the lamp and not drag the "lava" downward as gravity naturally does.

[Odo987]

The payload cradle swings outwards automatically so that the lamp is always pointed 'down'.

[pumpeduese137]

which can be clearly seen from the onboard perspective ;)

thx, cool vid

[nakeddraughtsman]

@Odo987 That is too clever :)

[Outlookhazy]

@Odo987 it swings out, but shouldn't it be allowed to tilt backwards too? it seems the "lava" is pooling on one side of the glass, and swirling in a strange pattern

[tlongj]

@metaldragon680 In a centrifuge the g-force is going in an outward direction. So to have the lamp go parallel with the force of gravity (created by the centrifuge) would be the only way to simulate the increased gravity of a place that has increased mass, such as another planet. Damn, don't kids study science anymore these days?

[ole9421]

I think i just got "geeked".

[yibb83]

awesome!

[franksters08]

lava lamp looks better on Jupiter lol :)

I want one of those new nexus one phone

[ryokaizero]

but why does it work? its like the G force didn't effect the fluid in the the lava lamp.

....

interesting...

[CloggedLacrimalGland]

Well, that was lame.

This video shouldn't have went too long if you hadn't shown off your fucking centrifuge.

And, the end? NOTHING!!!

What a waste of time, both yours and mine.

[lemmyliquor]

Does a fertilizer spreader work on Uranus.....?

[IMAKEYOURWIFESMILE]

Oh I didn't know I clicked on the Nerd channel

[conker3685]

Cool stuff.

[Jnod]

Dude! awesome!

[romanowski83]

jupiter..huh

[icelez]

where do you get those gears 90 degree ones

[IconProductionz]

FUCK NERDSSSSS

[sl2k4u]

did it work...?

[ZanderMander]

Haha a nexus :p

[MeganK987]

you have too much time on your hands. :/

[rubbershoes32]

@MeganK987 and your on youtube watching videos like this. whos to say that you dont either ^_^

[MeganK987]

thats not even bad, I mean so are you, if you obviously saw this, but I mean really, this guy built a fricken contraption in his own house.. about a lava lamp... hahahah.. I don't mean to hate.. buttt..

[TripLeSh0t]

lol. Advertising the Nexus One more eh? I'm buying 2 of them because of this video. I love it.

[Rillmeddy]

Kinda random but ur machine looks like a sex machine.

[JFTKproductions]

very cool

[jordan47473]

5/5

[SandraBullcocked]

I'm a bit unsure if this is the best use for a centrifuge. On the flip side this has been the best use of Lord of the Dance music in a video.

[jnrolf]

10/10 Just for the set up.. thats a lot of effort!

[aznlilhero]

what's the point of that? no trollin' seriously wondering lol

[tommyle5]

i wish i was a nerd =/

[blackchriswhitechris]

bodacious.

[werido55]

pretty cool

[RjTheGenius]

That's really awesome.

[eLLriDe420]

i masturbate when bored, this man builds giant metal things that nobody really cares about, but then again, they sort of do care about it. you know?

[Tex259]

I've got nothing to say about this video.

[m16mang]

Oh, I thought there was going to be boobs...

[killerfocker]

gay fucking retarded, if u wanna show off ur nexus one, u fail

[uCaNtCme11]

oh yeah im sure he built all that and made this whole video to show off his phone. fucking retard

[manoogianation]

you're dumb as fuck

[killerfocker]

@uCaNtCme11 lol ur the dumb fuck, of course i was being sarcastic.. why so serious? jus wanted to point out that this shit is craptastic

[Smartlack]

Erecto sets rock

[anava84]

can i have that machine?

[joekillerdude68]

@PandamoniumMedia FUCKIN SPAMMER

[atikokanite]

Nobody gives a shit queer

[riverlifeva]

sweet......can you build me a fucking machine;)

[HarryandKermit]

FAKE AND GAY

[AMart2300]

posting raywilliamjohnson quotes on every video you see that has nothing to do with what ur saying isnt funny

[HarryandKermit]

whatever you are FAKE AND GAY

[Odo987]

Use FedEx.

[VVVic411]

FUCKING USELESS

[Tony3821]

FOR SCIENCE!

LETS DO ITT!!!!!!!!!

[Maziyar]

good job.

everything is the same

results are in

same.

...

damn what a prick

( me )

lol.

[stavrosteve]

Somebody has way too much time on their hands. Kudo's, it's where some of the greatest inventions come from.

[whorebucks]

go cure a disease or something

[pagloota]

I love science

[matttitaly8]

holy shit!

[afaustino22]

i like how he does this indoors. nice..

[MachShot1337]

One word:

SCIENCE!

[RobotProductions09]

that was so intence!

[JLsoft]

"up" would be towards the center of the centrifuge...

[feleris]

Beautiful! How fast this centrifuge goes?

[twigon]

@feleris over 9000 rpm

[feleris]

thanks

[captBLOTTO]

its over 9000!

[twigon]

@captBLOTTO what? 9000!?

[captBLOTTO]

@twigon vegeta!!!! what does the scanner say about the lava!!!?!?!?!

[NFS104]

wow it does kinda

[Moesyzslak]

get a girl, a job, a life! come on!

[Ivan1993N]

you sir need that

[allaplomb]

@Moesyzslak: You do realize that this IS having a life. I think it's awesome. :)

[adriansalamandre]

Can you do one with someone walking unsuspectingly into the room with a tray full of cakes and ginger ale?

[iiWolf]

@adriansalamandre haha you would think of that

[JH4DS]

Awesome : This guy.

[DanielBass16]

cool!

Wow awesome. Can
