We've all heard the story about the MacDonald's burger that will not rot. Apparently because of the evil preservatives in them. Well, someone decided to test this theory by using eight different types of burgers including home made ones and different types of MacDonald's burgers to see which burgers would and would not rot, and then explains the most likely reason why the MacDonald's burgers do not rot. (I'll give you a hint, it's not the evil preservatives*) Go read the whole thing, it's well worth the time.
Hattip to Blunt Object.
* Don't worry there's plenty of other reasons not to eat MacDonald's (the horrible taste for instance), it's just that the 12-year old burger isn't one of them.
