Curious kids ages 4–10 will meet the Nabataeans, the clever desert traders who grew fabulously rich from camel caravans, learn why the giant "Treasury" holds no treasure at all, and uncover the genius trick that let thousands of people live in a place where it almost never rains. A true story of cleverness, curiosity, and one of the New Seven Wonders of the World. Turn your imaginations ON!
