Fracto-emission of light

    if you stick elastic tape to glass or to itself, walk into a dark room, let your eyes adjust, and then peal the tape off, you see faint blue light
    why does this happen?

    Perhaps the glue in the tape is slightly fluorescent?

    I read something about a potential, oxygen in the air being broken up, and an electron jumping the gap.. but I don't get why there would be a difference in electric potential or where the energy to ionize oxygen comes from (if this is even what they meant by "broken up"...)

    I tried to look up how adhesives work but apparently its a mystery, there are only models and theories (the bad kind of theories)
