  • 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!

  • Thank you very much, derkozten. =)

  • 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.

  • 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 =)

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

  • 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.

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

  • 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.

  • iQue brillante! Sin duda, quimica es magico :)
