Can an egg fall off a four-story (四层的) building without breaking? Can a person who weighs 90 kilograms stand on top of eggs without breaking them? Can a cooked egg fit inside a small bottle? Students at the High School Affiliated to Shandong University tried to do all of these things. On March 22, they did 17 different experiments (实验) using eggs. This was part of their winter holiday science project, which was themed around eggs. Students learned about different subjects, such as physics and chemistry, as well as improved their problem-solving abilities. TEENS
