This thing has popped up again and again over the years.
"McD's burgers don't rot!"
As one of you pointed out, usually, an experiment needs to have a control.
When you test something, you need to have another set as well.
Control: The control is a particular sample that is treated the same as all the rest of the samples except that it is not exposed to manipulated variables.
-----------------------------------
I find this fella's experiment much more in line with scientific requirements. He charted, measured measurable changes to the burgers such as weight etc.

Despite that, it is still flawed experiment.
Because the burgers are not prepared from the same place, the same way.
----------------------------------------
If you want the McD's burger to rot, just put it in a zip bag, then leave it on your desk. I bet you it will grow molds.
If you watched Morgan Spurlock's Super Size Me(The guy used himself as an experiment by eating lots of McD everyday to prove it was bad), just put the burger in a jar, and cap it with a lid. It will grow molds.
If it wasn't food, it won't mold. Whether it was in a zip bag or a jar. But it does.
So, it shows that it just needs the right condition. It needs enough moisture.
More reading if you have spare time and why it doesn't turn bad, not because it is 'not food'.
