Nastya sits on a chair and inflates a large blue balloon. Each time she changes her body position, so that the pose would be as comfortable as possible for inflating the balloon. Nastya is expecting an explosion, a deafening clap. Her every breath fills a balloon. The girl is tense. After the explosion, the girl's eyes widened. She was scared and delighted at the same time. Nastya felt a thrill and slowly slid down the chair.
