Remember when triangles, electromagnetic fields, and strange encounters were just part of a word problem? Well, in this week’s episode, Lily and Chase test their knowledge on all the above, when they discuss the strange and unexplainable occurrences that take place at the Zone of Silence (Zona de Silencio), located in the northern center of Mexico. Afterwards, Chase makes history fun again for Lily when he discusses the paranormal side of Christopher Columbus’s voyage.
