A tool for condensing breathing water until it turns into drinking water
Ships often crash onto barren shores, and sailors go out and find nothing but sand, salt water, or hard rocks. An American invented a very simple tool that anyone who wants to avoid thirst places on their mouth. When breath comes out with water vapor in it, this vapor condenses in the container and turns into water, just like what happens in the heat when the outside of a cup gets wet with water that has condensed. As the amount of vapor condenses, the thirsty person drinks it, and their thirst decreases. A Bedouin in the caravan can put this tool on his mouth at night, and in the morning he drinks what has condensed from his breath and would not feel thirsty.
