Long before Supersize Me or Fast Food Nation, Matt Malmgren was making interesting discoveries about fast food. In 1989, the trailing edge of the mullet era, he bought two burgers — he ate one and put the other in his pocket, intending to eat it later, but subsequently forgot about it. A full year passed before he pulled his old jacket out of the closet again, rediscovering the burger — and to his surprise found it still looked and smelled the same as a new one. It hadn’t decomposed.
When he told his friends about it, they didn’t believe him, so he repeated the experiment, several times over…. Today he has the world’s largest burger museum. All perfectly preserved with a chemical cocktail that discourages (much smarter) animals and insects from eating them.
