Does this make you hungry? Burger King touts "no preservatives" by showing Whopper turn moldy

Food companies like to tout their freshness to consumers, and often brag of their lack of preservatives or additives in their food. Now Burger King is showing just how preservative-free their signature Whopper hamburger is -- with a video that isn't exactly appetizing.

The 34 day time-lapse begins with a fresh Whopper, carefully presented with fresh mayonnaise, ketchup, lettuce, tomato, pickles, onions and meat. Then the video accelerates and shows the lettuce wilting, mold sprouting on the meat, vegetable, and bread, until it ends as a decidedly un-appetizing fuzzy, greenish lump.

The spot ends with the words "the beauty of no artificial preservatives."
