The Briggs-Rauscher Iodine Oscillator

[SpankGod]

I'd froth significantly too if someone tried to neutralize me.

But in all seriousness, think about your own bodies for a second. We each consist of millions of chemicals that oscillate in complicated ways. That's how our nervous system functions, that's how we stay alive. In my opinion, we are a trickier cup of chemicals by far ;-). This is cool too! It's just not so rare to find oscillating chemical reactions when you enter the world of biology.

[BKMillMan]

What is making that thing spin in the bottom of the glass?

[SpankGod]

@BKMillMan Fucking magnets... how do THEY work?

[akolozvary]

If only you could mix a drink that does the same thing.

[dreamsn2]

Salt is salty.

[kyle028]

Did this in high school, SO BOSS.

[Levifriend01]

What sort of black magic is this?!?!

[DShephard91]

When the change occurred I half expected it to explode for some reason.

[KalEl600rr]

FUCK CHEMISTRY, i hate it i hate it i hate it so much i hate it more than physics

[renesrn]

Glorious

[watchabadger]

Makinbacon stfu are you really that dumb -_-

[tkent2009]

That is so cool

[makinbacon855]

all hes doing is pouring clear koolaid mix in u cant see the top DUH idiots

[6KING6PITBULL6]

This guys a meth cook

[gforcegravina7]

Equilibrium reactions are the coolest

[carlhileman]

I want one

[cheong4life]

I was too excited when the clear turned slowly back into blue to care that it wasn't supposed to do that.

[adityamenon90]

Make sure the beaker doesn't explode when you try to recreate this experiment children =)

[semsemsam]

Does it change color if you throw on it on someone's face?

[cjjfolan]

Science Fuck Yeah.

[makinbacon855]

FAKE AND GAY

[adityamenon90]

@makinbacon855 no-one asked for your introduction.

[6buster]

You're an idiot.

[Chemguy91]

@makinbacon855 this is actually a well documented reaction, sorry your failed HS chemistry

[prizim]

@makinbacon855 you are clueless.

[mmmitch643]

I WANT TO DRINK ITM

[squishmael]

So my chemistry-fu stopped at 11trh grade chem class...but how can this process be applied to any real world scenarios? (hopefully all good applications)

Awesome vid though, thank you so much for sharing!

[geofftubeyou]

Pretty neat. Enjoyed video.

[Sthrudel]

Can you drink this? Would shit change color? That would be pretty awesome.

[MrJp0502]

KILL THE WIZARD

KILL HIM

[MrClayweed]

i saw this on mr. wizard



[ThomasRuschke]

The Wadsworth Constant does apply: Reaction starts at around 1:50

[SeraphBJD88]

@EnderDio Lol!

[connor2444]

ITS ALL WAVES MAAAAN

[philogos0]

drink it.

[bjkjf76]

You should have said that the three potions shown at the beginning were divine gifts from God, and that the reaction when you mix the three is the basis of all of Time. Come up with a few more stories, start a cult and profit like the Scientologists.

[watchmendis]

what kind of black magic satan worshipper are you????

[TheWhiteStripes3]

nuhhh, God did it!!! =B

[alcfae]

WITCH

[emperor0013]

Awesome. I think I saw this as a child on Bill Nye the Science Guy.

[EnderDio]

We should cook meth. Hit me up, i know the streets.

[sdflksdfkfh]

Boring

[BalliSkate]

go to 1:45 and watch the all in the backround... doesn't look real to me.. except his camera is just focusing but i wont buy it til he uses a real camera with not so slow focus...

[squarebearable]

@BalliSkate really?.....

[hugochonshum]

now show us how to make meth

[frahniesuperstar]

Wadsworth...



[arrozhombre]

Mmm yes, quite.

[GrizzlyAmish]

CRAP, I blinked!

[dom214]

I was pretty amused when the color returns after settling, sort of like the reverse of titrating a solution.

[Stuyboyz]

"It gets pretty mad when you try to neutralize it." Completely understandable. :)

[mattblair92]

Cool shit starts at 1:15

[ayinozendy]

Question sir, where does it get its pigment? I've always wondered...

[NickyTheHack]

Ahh the classic The Briggs-Rauscher Iodine Oscillator

[21wakko12]

... I love science...

[richd506]

A fish swimming in there would be really confused...

[noATM1]

Walter White

[Micahlopl]

Awesoooooooooome



[CyberDruidtheModGod]

wow

[SardonicNihilist]

Needs more dubstep

[Grubz5]

Sniper learns how to turn jarate into oil and back again. Jara--NOPE! OIL!

[MrExcitingusername]

Fucking WOW!

[TheVark675]

SCIENCE!

[Thesexymexi1900]

Free Lava Lamp!

[SuperKawaiiCupcakes]

this seriously blew my mind.. this is sooo cool! I found this on reddit... Lol

[xmultify]

@SuperKawaiiCupcakes Same haha were you watching the thing about corn starch and water first?

[youpickmyname3000]

Amazing



[nklimek]

Is it possible cork the bottle once you get it to the point that shaking it clears it, but letting it set reverts it to blue? As long as its sealed properly, that would be a pretty neat desk toy.

[mrhomescientist]

@nklimek Unfortunately no, eventually the thiosulfate would finish dissolving and would run out. There is another demo called the Blue Bottle, though, that does exactly as you describe! Do a search on it, hkparker has a good video about it. It'll run out eventually of course, but lasts for a very long time.

[greenbooksamazon]

@mrhomescientist @nklimek I know of a similar but more fascinating oscillating reaction - a fractal reaction!

The Belousov Zhabotinsky Reaction (search on youtube)

I wonder if this can be corked and marketed as a power-free lava lamp?

[lso5027]

@mrhomescientist I was about to call bs on this till I saw "Blue Bottle".

[SENSIBLECHEMIST]

0.77M H2SO4?? are you saying it won't work with 0.8M H2SO4???????!

[Axiss360]

The first time I saw this, I thought you cut the video when it turned black/blue.

[prozacgod]

Could you imagine seeing this for the first time. OMG I want to see this happen, in like a 30 gallon tank ;)

[hayjude99]

Can the Sodium Thiosulfate be the pentahydrate, because that's all I can seem to find easily. Or is that what you're using anyway?

[mrhomescientist]

@hayjude99 Yeah that's all I use. You're just mixing it back into water anyway, so anhydrous is unnecessary.

[hayjude99]

@mrhomescientist Exactly what i figured, cool

[Oskar3855]

Can the malonic acid be substituted with any other more easily available acid? Also does it have to be KIO3 or does KI suffice?

Anyway, really awesome video.

Thanks!

[mrhomescientist]

@Oskar3855 Hey sorry for the slow reply. I don't think any of those substitutions can be made. According to the paper I list in the description, you need malonic acid and at least the iodate ion. Feel free to experiment though, there's a couple different versions of this experiment!

[DoktorKlawonn]

The cloudy precipitate @ 8:20 is manganese hydroxide or carbonte depending on what you've used to neutralize the mixture.

[chemicalsymphony]

What happens if you don't stir the reaction with a stir bar?

[2Lazy2ThinkOfSomthin]

To revive the 'dead mixture' you can add a pinch of sodium hydroxide and a splash of high concentration H2O2 and a bit of crushed ice to stop the H2O2 from decomposing from heat and the iodine from subliming. Can revive it 2-3 times but it's too dilute after that, caution with the lye because like thiosulfate it gets angry. ;-)

[xd1248163264]

I think that cloudy solution may actually due to the decomposition of thiosulfate in acidic environment. Anyway, nice video and interesting reaction!

[elementguy27]

cool vid!

[asmathyder]

nice.........really interesting chemistry :)

[nodariel]

Amazing video :)

[hkparker]

Nice!!

[ferret0rouge]

very nice =]

[coolliger]

neat!

[myst32YT]

Very cool!!! Thanks!!

[BorderCityBandit]

very cool.

[Aranwu]

awesome this is so cool to see this reaction on HD :D
