Sally Davies, a New York-based photographer -- and decades-long vegetarian -- took a McDonald's Happy Meal home six months ago to see if what she had read online about a school teacher with a 12-year-old McDonald's burger could possibly be true (spoiler alert: it is). Davies' friend claimed the food would mold or rot within 2-3 days and that the story of the 12-year-old burger was nothing more than a tall tale.
The Happy Meal stopped smelling of anything after only a couple days, and the only change that really seemed to occur was that it essentially plasticized. "At six months old, the food is plastic to the touch and has an acrylic sheen to it. The only change that I can see is that it has become hard as a rock," Davies told the Mail.
