The team at BuzzFeed bought 7 cheeseburgers from different restaurants. They put them in glass jars to see how they would look after one month. They bought burgers from McDonald’s, Burger King, Wendy’s, Carl’s Jr., Jack in the box, In-n-out, and Umami Burger. Check out the video to see how they look after 30 days.
