HAPPY MEAL EXPERIMENT, KEEPING A HAPPY MEAL FOR 12 YEARS UNCHANGED

"The results? "The only change that I can see is that it has become hard as a rock," Davies told the U.K. Daily Mail.

She proceeded to photograph the Happy Meal each week and posted the pictures to Flickr to record the results of her experiment. Now, just over six months later, the Happy Meal has yet to even grow mold. She told the Daily Mail that "the food is plastic to the touch and has an acrylic sheen to it."

Davies -- whose art has been featured in numerous films and television shows and is collected by several celebrities -- told The Upshot that she initiated the project to prove a friend wrong. He believed that any burger would mold or rot within two or three days of being left on a counter. Thus began what's become known as "The Happy Meal Art Project."

"I told my friend about a schoolteacher who's kept a McDonald's burger for 12 years that hasn't changed at all, and he didn't believe me when I told him about it," Davies told us. "He thought I was crazy and said I shouldn't believe everything that I read, so I decided to try it myself.""
