"This Friday we'll have the yearly Egg Drop Challenge," said our science teacher, Mr. Baker. "You can work alone or with a partner."

　 My friend, Cassie, and I smiled at each other. We always worked on projects31_.

　 The　 32　　 of the Challenge was simple—to build a protective container to keep an egg from breaking when　 33　 the stadium wall.

　 I made my sandwich that afternoon while waiting for Cassie.　 34　 the butter cream gave me an idea.

　 "That looks like egg drop soup, Laura," Cassie said. She was holding her Egg Force One. My 47 _ raced. Had she won? I looked at her basket　 48

　 "My egg bounced 　 49 _," she explained, pointing to a broken shell.
