I remember in my biology class our teacher showing us the dreaded lung pictures, it made the act of smoking even less appealing. However, I remember from Jamie Oliver's Food Revolution he showed what was truly in the McNuggets. At first the kids were disgusted but then Jamie fried them up and asked who wanted one, all the kids raised their hands excitedly. I could see this work but we would need some truly powerful images. To bad we couldn't get a group of kids to sit through Food Inc.
