今天，爸爸让我做一个有趣的实验，就是把一根筷子放到一个装满水的的杯子里。
Today, my father asked me to do an interesting experiment, which is to put a chopstick into a cup full of water.
“爸爸，大事不好了。筷子弯了。”
"Dad, it's not good. The chopsticks are bent. "
爸爸笑咪咪地说：“其实，筷子并没有弯。这是一个光的折射现象。以后到中学，学了物理就知道了。”
"In fact, chopsticks are not bent," he said with a smile. This is a refraction of light. I will know when I learn physics in middle school. "
真是一个有趣的现象。
It's an interesting phenomenon.
