The glow light is made of two parts which when mixed together create the chemical reaction which makes them glow.
4 g sodium carbonate
0.2 g luminol
0.5 g ammonium carbonate
0.4 g copper sulfate pentahydrate
approx. 1 litre of distilled water.
50 ml of 3% hydrogen peroxide.
This is all I could find.....

First you need a diphenyloxalate, such as
bis(2,4,6-trichlorophenyl)oxalate

Secondly, you will need Hydrogen Peroxide. You can get 30% H2O2 in the haircare section of the pharmacy. It is used to bleach hair. This is whats in the glass vial inside the lightstick that you break in order to start the reaction. Apparently it is a dilute solution of hydrogen peroxide with sodium hydroxide (lye, you can get that at the hardware store)

Third, you will need a chemiluminescent dye, choose one based on the color you want:
Blue: 9,10-diphenylanthracene

Green: 9,10-bis(phenylethynyl)anthracene
http://www.sigmaaldrich.com/catalog/search/ProductDetail/SIAL/264199
Yellow: 1-chloro-9,10-bis(phenylethynyl)anthracene
(aka Rubrene)

Orange: 5,12-bis(phenylethynyl)-naphthacene
(aka Rhodamine 6G)

I'm afraid I don't know the exact proportions or concentrations needed for optimal results. I'm also not sure if it is an aqueous solution, or some other solvent but the lightsticks are usually touted as non-toxic so it can't be anything too exotic. Anyway, thats part of the fun of experimentation. Figure out what works best.

Capture some fireflies and put them in a jar!
