It's gray. It's bubbly. It piles up several feet thick. It pulsates like something alive. Worst of all, scientists still don't know what it is, just that it's filled with weird bacteria that have no right to be there. It contains poisonous gases like hydrogen sulfide. Most notably, it's extremely rich in methane, which, as anyone who has been drunk enough at a party to try to light a fart knows, is super flammable. So what happens when a spark lands on the foam?
An hour at 350 degrees becomes six seconds at 4,000 instead?
Pigsplosion. The foam and all the shit blow up. Blue fire tears across the foam, melting plastic and metal. The blast rips apart the pit and the barn. Shit, foam, flame, and hog flesh meld together, and the pigs die by the thousand.
These hog shitfernos are a new phenomenon, and no one's quite sure why they've started now. They could have something to do with the pigs' diet, mash left over from making ethanol fuel. We might have created the conditions necessary for the crazy new bacteria to thrive. But once you've blown up your pigs, there's not much point in wondering why it happened. You just scrape up the crisp pork and put it on toast. Bacon's bacon.
