@sally.0115: High temperatures in October, but we survived the heatwave at Disneyland! No crowds and wait times were about 5 to 15 min. #disneylandcalifornia #heatwave #anaheimcalifornia #october #southerncalifornia

What you are watching is how US soldiers literally disappeared in plain sight during the Vietnam War, and the detailed explanation behind this camouflage technology is genius jungle warfare engineering. The soldier you see vanishing under the leaves is using a technique called natural camouflage and the Ghillie suit principle. In the dense jungles of Vietnam, the Viet Cong mastered the art of becoming part of the forest floor. They did not use high tech gear, they used science. They covered themselves in decaying leaves, mud and branches that matched the exact color temperature and texture of the forest floor. The human eye detects movement and outlines, not color, so by breaking up the human silhouette, the brain completely ignores the shape. The US Army later adopted this and created what is known as the leaf suit. The material science behind it uses jute and burlap strips that mimic how light scatters through foliage. When a soldier lies perfectly still, his body heat is also trapped under the damp leaves, which reduces his infrared signature. This is why in the video you can walk right past him and not see him until he moves. The mechanism is called disruptive coloration, the same trick tigers and chameleons use in nature. This tactic was the reason ambushes in Vietnam were so deadly. A whole squad could be lying 5 feet from a trail for hours, breathing slowly, invisible. This everyday science of survival and military engineering shows how understanding human vision can make you vanish without any technology at all. #vietnamwar #camouflage #militaryhistory #junglewarfare
