This week we explore the bizarre true story of an invisible barrier inside a 3M manufacturing plant that workers could feel as they walked through a doorway. It sounds like science fiction, but it was actually caused by massive static electricity fields generated during high speed film production. We dig into the physics, the engineers who investigated it and the other strange static related stories that make this one of the most surprising manufacturing mysteries ever to happen inside 3M.
