We’ve all seen the photos of the McDonald’s burgers that still look the same after 10 years. Well, Burger King is going a different route. To show consumers that their newest Whopper doesn’t have any artificial preservatives in it, they have just released a time-lapse video of the popular burger as it slowly grows mold over the course of 34 days.

While some may think the idea of watching a burger slowly rot as gross, it’s admittedly effective at driving home the point. Now the question is whether or not fans will want to eat a Whopper after watching it turn into a science project before their eyes.

The beauty of real food is that it gets ugly. that’s why we are rolling out a WHOPPER® that is free from artificial preservatives. isn’t it beautiful? #NoArtificialPreservatives BURGER KING® is rolling out a WHOPPER with no artificial preservatives, which is currently available in more than 400 restaurants in the U.S., and will reach all restaurants in the U.S. by the end of 2020.
