Did you know that liquid nitrogen kills zombies? Ok, I know technically zombies are dead already, but this nitrogen stuff sure does work. It kinda just freezes them in their tracks! I’m talking, no more eating brains or scratching and biting. Nothing, just a zombie popsicle. Now I know why I see so many canisters of liquid nitrogen just hanging around on the streets of New York. We are just extra prepared for the zombie apocalypse.
