This week, news about a New York City photographer, Sally Davies, shocked and rocked the world.

She bought a McDonald's Happy Meal which include a burger and fries on 10 April (six months ago) and until today, the food still looks edible without any moulds.

The first thing which crosses our minds is what the hell did the fast food contain? Preservatives? Or some secret which McDonald's did not disclose to the public?

Miss Davies placed the Happy Meal on a plate and left it untouched for half a year. She snapped pictures of it daily and posted the photos online. You just have to Google "sally davies mcdonalds" and you can see them for yourself.

Some people started suspecting the fast food chain while others suspected the woman who carried out the experiment. I believe that it was a genuine project since there are news of other similar experiments.

Is it miraculous or what? Maybe you can try it out yourself at home.
