"Kate McGroarty won "A Month at the Museum," an intriguing contest at the Museum of Science and Industry in Chicago. The prize was 30 days and 30 nights living in the museum. For her, it was more than entertainment. During the day, McGroarty frequently accompanied schoolchildren to science learning labs. She wrote about her escapades and posted photographs on social media sites. At night, she investigated the exhibits by herself before falling asleep in them. She slept on a huge hamster wheel one night and inside a German submarine from World War II on another. At nine thirty each morning, she would watch the museum come to life when the coalmine whistle blew as the museum opened for business."
