When does Weird but True! return?

The Engelman siblings explore "weird but true" things about a broad-range of subjects. They interview experts and travel to locations such as crime labs, amusement parks, and the Everglades to find answers to their questions. Inspired by the National Geographic book series of the same name, much of its style and heavy use of paper models created by the Engelmans are continued from their earlier National Geographic short video series Nature Boom Time.
