If something hits you on the head while you are wearing this safety helmet, its soft flexible inner layer will instantly turn into a rock-hard shock-absorbent material. The helmet is lined on the inside with a material that is soft and flexible under normal conditions, but which "locks" instantaneously, becoming hard and shock-absorbent, if the helmet is subjected to impact or blows.
