I love you

This video went viral on Budapest

Hello there,

I'm going to be running a stand for the RSC at BT young Scientists in Dublin and I’d like to show this. Is it possible for the solutions A, B and C to be prepared in advance and are they safe enough to transport? Also is this OK to be done without fume hood ventilation? Is there any way to make is last longer than about 5 minutes?

Kind Regards,

Sonia Olejarz

Great video, great explanation. Thank you from Rio de Janeiro/Brazil.

[pannfredrikaka]

Jcool! ust a shame it only goes on for 5 minutes.

[militantmindset]

amazing thanks for sharing

I tried out differant methods of measuring/recording oscillation periods for this reaction once for a project: it worked fine in general, but a temperature probe I used showed almost no fluctuations in temperature. Was it something I effed up on, or should their be little change between oscillations?

this is justin beieber's anti-puberty potion.

[gotztago]

iQue brillante! Sin duda, quimica es magico :)

[jordandaniels7]

Could you please post your procedure, or maybe a link to one that is the same as yours?!

PS, If youre going to try this, make sure you use the boiling water, it doesnt work otherwise.

[mrhomescientist]

Amazing video! I'm going to try this myself in the near future, it's an extremely interesting reaction. Your explanation was excellent. My favorite part was actually right at the end, when it looked like the thiosulfate had cleared it up, but then the iodine came back with a vengeance :) Keep up the great work!

[agentdarkboote]

Like if you're here from nano =D

[actor2120]

you are very talented! well done! you deserve more views on this!

[xCaleb774x]

haha did you have to pour everything in so slowly? I need to pee now.

[JBJohnstone]

Hi, thanks for this video.

I am studying this reaction for a chemistry investigation, and am having some trouble dissolving Potassium Iodate.

At the moment, I have had it in about 50C water on a magnetic stirring plate for about 1hr45 and have a pinkish solution with lots of sediment.

Should it take this long?

How can I make it dissolve faster?

[haoyuan93]

well u need hot water to rapidly dissolve potassium iodate.boiling or close to boiling water is recommended.

[goldeneye7100]

Magnifique

[MOURISOUITIROU]

わお。

[kingkongtiger]

Interesting

You may add the equations for one who is interested in

[howard18plus]

lol sick

[chrismckormick]

When the camera first panned over to the third container I thought it was going to be a jar of mayo.

[cdl81596]

hahaha me too

[mozo25]

why does it change color?

[makuserusukotto]

The video said exactly why it changes colour. You need to pay attention more.

[Peterditaa]

the good old iodine clock experiment. i read bout that today in one of my römpp books^^

[arande3]

Wow sweet!

[CWSSje]

crap!! that last bit of reaction before you get the clear reaction is sooo alike the hollow -ichigo hierachy in the anime "Bleach"  it kicks ass man. damn good science is FUN

[tounssi1990]

stfu

[jdyson0287]

Bravo! The only version of this reaction I've seen on youtube that actually demonstrates the oscillating nature of this reaction i.e. the 'clock' part. Finally somebody understands why the reaction has this name!

[sockpuppetsfromhell]

interesting

[sciencoking]

4:04 oh this is how they make coke! :PPPPPPP

4:23 sodium thiosulfate owns!

4:33 wtf iodine owns back o_O

[dbc616]

See, chemistry is fun!

[EarlRausch]

Very nice. Well done

[chandlerbeckhoff]

dear mabakken,

your vids are awesome!what is that magnetic stirrer you use in all your vids called im tired of using glass ones they always break on me!

[cantaloup3]

Awesome video! Very well done.

What were the initial concentrations (dilutions) of the chemicals you used?

[adriankocian]

HI mabakken! =)

i would like to ask you when you add some new videos:) I can´t wait anymore :D:D You should add basic things as filtration or filtration at low pressure using Buchner funnel:) Thanx :D

[adriankocian]

Sorry, I haven´t known it. So I hope you like Budapest. You can visit SLovakia. Exactly trnava. :D You can visit me :D

[Pyrotrons]

Incredible video. Make sure you tag this right, so people can find it. I think your tags are a little too narrow right now...very few people are going to search for those terms. Use something like "chemical science experiment color change lab burn fire explode..." you get the picture ; )

[Basco36]

I like doing this reaction.

[derkozten]

E X C E L L E N T ! ! !

I've never seen this reaction so clearly, until now. The "blue incoming" is so sharp... it almost looked fake, as if a completely different blue beaker were put between the "transparent beakers" shots.

Of course, there is no actual fake at all. Brilliant!

[mabakken]

Thank you very much, derkozten. =)

[derkozten]

Do you know of a website where BROR (Briggs-Rauscher...) is well explained?

I'd really aprecciate it.

[davidkoster]

Super video!

If you have time,can you make a video about the synthetis of 3 nitrophtalic acid ?

I want to make that,but it's not really easy.

[mabakken]

Thank you =)

I have the time, but unfortunately not the chemicals needed. As I specialize in inorganic chemistry, o- Xylene and Napthalene is not available to me as of now. I would need these chemicals to make Phthalic anhydride, but if you have this chemical, it is only a matter of a nitration. If you want the details, PM me.

I'm sorry I couldn't be of more help =)

[andreichikachika]

great job!

[smiles76239]

Amazing as usual! 5/5

[AstroliteG]

Great video! 5*!! :) We did this at school once!
