A Flux 2 response device is seen among Wyoming Valley Ghost Tours selection of paranormal investigation equipment at the Albright Memorial Library in Scranton on Thursday, March 11, 2021. The pyramid-shaped device is used by paranormal investigators to try to get answers to yes-or-no questions or other questions with two possible answers. A light on either side at the top of the pyramid activates as an indicator of an answer. Wyoming Valley Ghost Tours has partnered with the Scranton Public Library for a history tour and paranormal investigation in April.
