After reading The Wonderful Night of the Museum, you must know that many scenes are taken at the National Museum of Natural History in the United States, such as talking stone people, moving elephants, and so on. So you can't miss this museum when you come to Washington, not only because it's free. Before I came here, I always thought it must be very big, but the fact is not so. The natural part is not much. Instead, what attracts me is the ore and jewelry part. For the first time, I know which minerals gold, platinum, copper are extracted from, and then I am amazed by 1000 carats of diamonds. It's definitely worth a visit.
