I'm sure they have already figured out that if you just walked around a terminal with a water bottle full of hydrated pureed seaweed and a little syringe to spray it, every EDT machine in the zip code would go crazy. Or they could just paint a little watercolor stripe on random bags. Watercolor manufacturers add glycerol to keep the paints from drying too fast. Glycerol, which is the proper name for glycerine will trigger an EDT machine.
