比赛的第一个环节是“气球传递”挑战。规则看似简单，却极大地考验着同学们的协作与默契。每个班级选出十位同学站成一列，他们的任务是将装满水的气球从队首开始，依次向后抛传，最终让完好无损的水球落入队尾的水桶中。这个环节的关键在于，传递全程只能向后抛，这意味着每一位同学都无法看到身后队友的位置，只能凭借彼此的信任和默契来完成。

随着裁判一声令下，第一颗水球被高高抛起，在空中划出一道道略显“紧张”的弧线。有的队伍配合默契，水球在同学们手中平稳传递；而有的队伍则稍显慌乱，水球在中途不幸“牺牲”，溅起一片惊呼和笑声。这个环节充满了悬念，因为大家辛苦传递成功的每一颗水球，都将成为下一回合狂欢中的“专属武器”。这不仅是一场竞技，更是为接下来的激情释放积蓄力量。

当传递环节结束，真正的狂欢正式拉开序幕。同学们手持着在第一轮中赢得的水球，并纷纷亮出自带的各式水枪，操场瞬间变成了一个充满欢声笑语的战场 。大家的目标不再是赢得比赛，而是尽情地享受“玩水带来的快乐” 。

同学们迅速组成联盟，运用各种战术：有的负责正面吸引火力，有的则迂回包抄，声东击西 。水流在空中交织，水球在人群中绽放，陌生的隔阂在清凉的水花中瞬间消融 。更令人惊喜的是，校长和老师们也全身心地投入到这场水仗中 。他们或是手持水枪与同学们“对战”，或是在混战中被“围攻”，师生之间亦师亦友的关系在这一刻得到了最生动的体现 。每个人的脸上都洋溢着兴奋的神情，衣服早已湿透，但心中满是酣畅淋漓的快乐 。

The first segment was the "Water Balloon Relay." Though the rules seemed simple, they greatly tested the students' coordination and tacit understanding. Each class selected ten students to form a line. Their task was to pass water-filled balloons from the front to the back by tossing them backward, ultimately landing intact balloons into a bucket at the end of the line. The key was that every toss had to be made backward, meaning no one could see where their teammates stood—relying entirely on trust and Coordination.

At the referee’s signal, the first water balloon was tossed into the air, tracing a somewhat "nervous" arc. Some teams worked in perfect sync, passing balloons smoothly down the line, while others were less coordinated, resulting in balloons "sacrificing" themselves mid-air, accompanied by bursts of surprise and laughter. This segment was full of suspense, as every successfully passed balloon became a "exclusive weapon" for the next round of fun. It was not only a competition but also a buildup to the excitement that followed.

Once the relay concluded, the real happy began. Students armed themselves with the water balloons they had earned in the first round and brought out their own water guns, instantly turning the playground into a joyful battlefield. The goal was no longer to win, but to fully enjoy "the happiness that playing with water brings."

Students quickly formed alliances and employed various tactics: some drew attention head-on, while others flanked or distracted. Water streams crisscrossed in the air, balloons burst among the crowd, and any sense of unfamiliarity melted away in the cool spray. To everyone’s delight, the principal and teachers wholeheartedly joined the water battle. They either "fought" students with water guns or found themselves "surrounded" in the chaos, vividly illustrating the bond between teachers and students as both mentors and friends. Everyone’s face glowed with excitement; clothes were thoroughly soaked, but hearts were filled with sheer joy.
