![]() And in 2006, a team of scientists including Sir John Pendry developed a sort of proto-invisibility cloak that was able to manipulate the electromagnetic spectrum using artificial materials, designed to exhibit light-bending properties not found in nature. The military tech space is understandably intrigued by camouflage that actively adapts to the background. There have also been plenty of legitimate, non-hoax attempts at invisibility cloaks and related tech. ![]() If a person or vertical object stands in a dead spot of a vertical lens, then the light doesn’t hit them-they become essentially invisible. Instead of continuing in a straight line, the light is slowed and redispersed at different angles, creating spots where the light no longer passes through (Cramer calls these “dead spots”). The plastic lenses refract the light as it passes through. It looks like a magic trick, but it’s just science. Turn it horizontally and the other pencils disappear, while the vertical pencils jump back into sharp focus. When the lens is oriented vertically, all of the vertical pencils become blurred to the point of invisibility. This gif (which recently made the rounds on Twitter) shows a stacked grid of colored pencils through a lenticular lens. And definitely not the entire visible spectrum,’” he says. ![]() But you definitely can’t do two frequencies at the same time, if one is red and one is blue. “Physicists were saying, ‘well we know we can bend light at one specific frequency. According to Cramer, physicists were skeptical that something like this was possible. What Cramer realized is that a clear sheet of these lenticular lenses can bend the full spectrum of visible light (it can also bend near infrared, near ultraviolet, and thermal spectrums).
