More details in full description. Dr Sam Tang adds hydrogen peroxide to pyrogallol, formaldehyde and luminol. Chemiluminescence is caused by molecules being formed with some of their electrons in a higher energy level and then losing that energy as light. In the first stage, pyrogallol (1,2,3-trihydroxy-benzene) reacts with hydrogen peroxide and formaldehyde to generate singlet oxygen (O2 with the electrons paired together). This then converts to triplet oxygen (O2 with two electrons unpaired -- see our video of magnetic oxygen) with a weak emission of red light. The reactions also generate heat, which is why the temperature goes up and it's the liberated oxygen gas which causes the bubbling. Then the luminol reacts by losing N2 from the molecule to form an excited state product to emit blue light. You can see that with all of these reactions going on at the same time, it's not easy to write down what's happening in just a few simple equations.

Learn more at http://www.google.com/chromecast NOTES 1. Music by Alan Stewart - Alan played the music in one take while watching the video for the first time! Alan: http://www.youtube.com/user/AlanKey86 2. The ethanol demonstration was intended to show the liquid would burn without damaging the object we doused. We chose a currency note because everyone is familiar with it - knows what is made from, feels like, etc. And they would know it is not a trick substance. There was no intent no cause any damage - just educate and entertain. You can bid on the $50 in our charity auction... http://www.ebay.co.uk/itm/380797103246 3. The Potassium Nitrate - which also didn't go the plan - was designed to reveal a message on the paper - you should still be able to see it! (periodic videos loves to share all our demonstrations with you - even when they don't quite work or fail completely - you can learn much from so-called "failures") 4. The video was filmed in Neil's fume hood - where else?
