Fast food test

Have you ever wonder what's in that McDonald's hamburger? Ever wonder how and/or why you can leave out for months on end and it will never spoil? Do the test and buy a hamburger and set it out and see how long it will stay on the counter without spoiling. Kinda scary...right? Now rush right out and get that happy meal and don't forget your "diet soda" because after all you are watching what you eat.
