A other nice reaction is the chemiluminescence of luminol in alkaline DMSO (dimethyl sulfoxide)  which is here  http://illumina-chemie.de/chemofluoreszens-des-luminol-dmso-naoh-systems-t3116.html described.  bombjack Here are my synthesis trials (sorry, partly in German; but with pictures and some links to “English speaking” pages ):

I hope people don't feel the need to change their voice just to sound more "authoritative" -- that's just plain silly.

Also, is it possible to slow the rate of decay by freezing the mixtures? Probably not, and I realize they'll always decay, but I can't help wanting to experiment.

I had no idea what was in the glass tube that activated the fluorescent dye. Now I know that it's the same thing that makes me glow. Thanks for clearing that up.
