Looking almost as fresh as the day it was bought, this McDonald’s Happy Meal is in fact six months old. Photographed every day for the past six months by Manhattan artist Sally Davies, the kids meal of fries and burger hasn’t any signs of mould(霉菌) or decay(腐烂).

Sally put the Happy Meal on a shelf in her apartment and watched it with increasing shock. Even her dogs stopped trying to steal a free tasty snack.

“I bought the meal on April 10 this year and brought home to see how it changed,” she said. “I chose McDonald’s because it was nearest to my house, but the project could have been about any other fast food. The first thing that shocked me on the second day of the experiment was that it no longer gave out any smell. And my dogs stopped circling the shelf.”

Sally expected the food to go mouldy after a few days. In fact, Mrs. Davies’ surprise turned to shock as the food still had not shown any signs of decay after two weeks. “It was then that I realized that something strange might be going on with this food that I had bought,” she explained. “The appearance of the food did not change as the weeks turned to months. And now, at six months old, the food is plastic to touch. The only change that I can see is that it has become as hard as a rock.”

The experiment has brought her amusement rather than fear. “Maybe I would be frightened at seeing this if I were a meat eater.” she said.
