Every weekday, we recommend a podcast related to a movie or TV show you can watch at home: For decades, people have been fascinated by crop circles. What started out decades ago as simple shapes, has evolved into complex geometric patterns. Crop circles appear overnight but to this day, nobody knows how they form. For more episodes like this one, subscribe to Unexplained Mysteries on Spotify. Also, check out the film Signs, which is now available to stream!
