１９８２年笔者在物理课外活动中组织过一次全校性的“落蛋”比赛．当时要求将新鲜的鸡蛋经包装以后，从教学楼二楼的高度释放，落至水泥地面上，以鸡蛋完整不破作为评选标准．到了１９９０年又将此比赛冠以“鸡蛋撞地球”的美名，比赛的难度和规则更趋完善，要求从五楼 １８． In 1982, the author organized a school-wide “falling egg” game in a physics extracurricular activity. At that time, the fresh eggs were packaged and released from the height of the second floor of the teaching building and fell onto the concrete floor. In 1990, the competition was crowned with the title of “Egg Hits the Earth”. The difficulty and rules of the competition have become more perfect, requiring the fifth floor.
