"I wondered what this would do" - now we BOTH know... I bought a $1 "White/Blue" Glow stick at the local dollar store, and carefully cut the top off, pouring out the liquid into a test tube. I then took the internal glass tube with the other liquid (which normally breaks mixing the two inside the stick) and put it in another test tube, carefully breaking the glass and extracting the chemical. I then cleaned up the mess (the inside of the now empty glow stick) and the fraction of a drop left in the broken glass, with a paper towel (thus mixing "A" and "B"). I then went into a dark room with my Casio Exilim Z40 set to macro (about 6cm), roughly spread out the "dirty" paper towel, and took a 2 second exposure at equiv 200 ASA (makes it grainy). Post-processing consists solely of hitting the "balance" key in my "VuePrint" image browser, which increased contrast and brightness a bit. It reminded me of stars - and after all Stars are "self illuminating" when photographed, as was the subject of this photograph.
