PAGE, AZ (CNN) - There's a chicken sandwich floating above Earth.
Kentucky Fried Chicken sent its spicy "zinger" sandwich to the edge of the atmosphere Thursday.
The fast food chain partnered with Arizona company World View Enterprises on the ad campaign.
The sandwich is sitting on a high-altitude balloon, and is expected to stay aloft for four days.
The sandwich is at an altitude between 50,000 and 80,000 feet.
