What better weapon than the human brain? The human brain was Mrs Twartski's and Wiezenslowski's domain. The children who were used were the castaways of the United States government, like dogs abandoned and a vet's office. Mrs. Twartski read the letter out loud, slowly and carefully enunciating every word in her thick Polish accent. The German scientists were looking for children who could learn quickly, were between ages four and twelve, and could withstand being famished without dying. Deutschland were paying dollar $50,000 per subject. Everyone in living room exactly Mrs. Twartski and all my aunts let out a huge "Ahhh". My sister's and my eyes grew wide because we had no idea what this meant or why the adults were so excited. Then my sister's eyes narrowed as if she knew something that I didn't yet, as if she had just figured something out.
