The Complex Mechanics of Pyramid Doors

Were the pyramids closed for good when construction was done, or was there a door that allowed the initiated to access the internal passages? And if there was a door, how would such a door have worked and still kept the pyramid internal passages fairly concealed? Today we go deeply into this problem and along the way we tackle the psychology of pyramid defense, mechanical principles of pyramid door operation and concealment techniques. I even built a miniature cutaway of the Bent Pyramid's northern passage to help illustrate my points. I hope you enjoy this video and let me know in the comments if you want more models of complex pyramid parts, because I will keep building them anyways!!
