We're searching for truths about ancient civilizations, history, hidden knowledge, technologies, mysteries and curiosities, we may not have heard.
磁场观察膜 Magnetic field viewing film, It is a translucent thin flexible sheet, coated with micro-capsules containing nickel flakes suspended in oil.[1] When magnetic lines of force are parallel to the surface of the carrier sheet, the surfaces of the flakes are reflective, and appear bright. When lines of force are perpendicular to the sheet, the flakes are edge-on, and appear significantly darker.[2] When the film is placed on a magnet's pole, the latter case applies. https://en.wikipedia.org/wiki/Magnetic_field_viewing_film
