McDonalds' "Food"vs Real Food

I have a son that is a junk food junkie.  I mean, he would choose any fast food restaurant over a home cooked meal ANY DAY and EVERYDAY!  So I am going to do a little experiment, one I have seen the pictures from before(so I guess I am stealing the idea), but I want to experience it first hand in the hopes of curbing the monster within him.  Here goes:

First, the McDonald's hamburger.  Regular, nothin' special about it.  Ketchup, mustard, little chopped onions, pickle, what they call "meat", and a bun.

 Now the real hamburger, ketchup, mustard, little chopped onions, minus the pickle, 100% pure beef, and an organic bun.

They will be kept in identical containers on my kitchen counter for however long it takes to show some major degradation.  I labeled them and dated them.  This started on the 22rd of March.

I have been thinking of doing this for a while and the bread I needed finally went on sale at a time when I was contemplating the experiment.  When my neighbor brought the McDonald's hamburger over(bought on his way home from work. Thank you, Mark!), my junk food monster came running in and exclaimed " Is that for ME???"  Dear Lord, he is disappointed I am wasting this burger on an experiment!  The next morning, he said "Can I have it now?"  After learning it had sat out all night on the counter and would continue to do so until it rotted, he didn't want it anymore. 

My kids have watched most of Food Inc. and Sweetie Pie is not a fan of fast food anymore.  The Junk Food Junkie(otherwise known as The Rocket) on the other hand is only mildly deterred.  Zman is indifferent, and S just rolls his eyes.  My work is cut out for me...

I will be posting pics(I will try for weekly) on the progress of the experiment.  My hypothesis is that the regular hamburger, made of real food, will degrade(rot) faster than the McDonald's hamburger, because of the lack of preservatives in the ingredients.  My hope is that my Junk Food Junkie and his father will learn something about the "food" they love so much, and it will be burned on their minds, so as to never forget it. 

Is that too severe?   Naaaaa
