I was a cohost on this Peeranormal episode on Crop Circles.
Crop circles are well known — patterns that appear in fields of crops when certain areas of the field are compressed. Investigators have long noted how the stalks are bent uniformly, without visible damage. This episode of Peeranormal takes a look at some of the sparse academic peer-reviewed research on crop circles to discuss if they are man-made, created by an unknown natural force, or something paranormal.
