Have you ever caught someone drinking straight out of the milk carton? Does saliva wash back into the milk carton from your mouth when you take a drink? ScienceU campers tested for the amount of bacteria in milk samples when they drank directly from the carton ("backwash") and when they used a glass (the "control").
