A friend of mine told me this story. When his wife was pregnant, different strange ideas and dreams came to her mind. Once his wife asked him to walk with her late at night. When they were walking another strange idea came into her mind. She said that she wanted to eat ice and smell benzene at the same time. He was very surprised but he didn't want to say no to her. So, they went to a neighboring cafe and ask a bit ice. Then they went to a gas station. He said that it looks funny and very strange when his pregnant wife stayed at the gas station and eat ice.

As I know ice and the benzene smell help to avoid toxicosis. My idea is to produce pills against toxicosis which will consist of ice and have the benzene smell.
