有趣的实验—纸杯烧水

今天，我和爸爸妈妈合作做了一个有趣的实验—纸杯烧水，准备的材料有：打火机及一次性纸杯各一只，半杯清水和一根蜡烛。

today, i did an interesting experiment with my mom and dad - boiling water with paper cups. the materials we prepared were a lighter, a disposable paper cup, half a glass of water and a candle.

我们首先用打火机点燃蜡烛，让蜡油滴在桌子上，将蜡烛固定住，然后把装了半杯清水的纸杯轻轻端着移到火苗上，并开始记时。刚开始我探着脑袋从上往杯子里瞧，呀，杯子里竟然象点了盏灯似的亮堂堂的。我又从下往上看，杯底却是黑乎乎的，什么也看不清。

we first light the candle with a lighter, let the wax oil drop on the table, fix the candle, and then move the paper cup with half a cup of water gently to the flame, and start to record the time. at first, i looked into the glass from the top, ah, the glass turned out to be as bright as a light. and i looked up and down, and the bottom of the cup was black, and i could see nothing.

大约过了五分钟，我感觉握纸杯的手有点微微发热，就伸出一根用指试了一下水温，水已经有点了烫了，估计有二十度左右。这时，我不由自主的担心起来，“杯底会不会被烧破呢？”，“水会不会从破洞里漏出来呢？”。我继续一边心翼翼地端着杯子，一边仔细观察着杯底的变化。时间一分一秒地过去了，我感觉手都麻木了，心情也越来越紧张。大概又过了二分钟，我看见水好象要开了似的冒出了一个个细小的泡泡，好像一粒粒晶莹剔透的珍珠从水里冒了出来。不过我担心的事始终没有发生，我终于松了一口气，把杯子从火苗上移下来，使劲地顶了一下杯底，“呀！”我尖叫了一声，原来是杯底上的“黑墨水”粘在了我的手上，黑乎乎的一片，但杯子却完好无损。

after about five minutes, i felt that the hand holding the paper cup was slightly hot, so i stretched out a finger to test the water temperature. the water was a little hot, estimated to be about 20 degrees. at this time, i can't help worrying, "will the bottom of the cup be burned？" "will the water leak out of the hole？". i continued to hold the cup with my heart and wings, while watching the change of the bottom of the cup carefully. as time went by, i felt my hands numb and my mood became more and more tense. about two minutes later, i saw that the water seemed to be about to open, like tiny bubbles, like crystal clear pearls coming out of the water. but what i was worried about never happened. i finally took a breath of relief, moved the cup down from the fire, and pushed the bottom of the cup hard. "ah!" i screamed. it was the "black ink" on the bottom of the cup that stuck to my hand. it was black, but the cup was intact.

“咦，这是为什么呢？”，虽然我不知道这其中的奥秘，但这次快乐的体验让我体会到了科学的奥妙是无穷无尽的。

"why, eh？" although i don't know the mystery, this happy experience makes me realize that the mystery of science is endless.
