12 Getting Launched

CHAPTER TWELVE GETTING LAUNCHED Endothermic reaction (noun). This is a chemical process that absorbs heat. When you mix vinegar and baking soda together, you have an endothermic reaction. This is because it takes a bunch of energy to break up the baking soda and vinegar molecules. It's sort of like how it takes more energy to pull apart stacked LEGOs than to collect them from two separate piles. "ROLLS OF TOILET PAPER?" said Jeremy, his eyebrows raised in surprise. "That's the special material? Man, I should have bet on myself." "Who would have thought toilet paper makes the rockets really fly?" I fished out another roll from a package under the supply table.

第十二章发动吸热反应（名词）。 这是一个吸收热量的化学过程。 当你把醋和小苏打混合在一起时，就会发生吸热反应。 这是因为分解小苏打和醋分子需要大量的能量。 这有点像拆开堆叠的乐高积木比从两堆分开的乐高积木中收集它们需要更多的能量。 “几卷卫生纸？”杰里米惊讶地扬起眉毛。 “这就是特殊材料？” 伙计，我应该把赌注押在自己身上。” “谁能想到厕纸真的能让火箭飞起来？”我从桌子下面的一个包裹里掏出另一个面包卷。

"TP is essential," said Jeremy, who balanced the roll on his head. "Especially because the rolls make nice hats." "Ha ha," I said. "The toilet paper is for little fuel packets of baking soda," said Tala, pulling off a sheet. "You put a tablespoon of baking soda in the middle of one square. Then cut off a piece of string and tie the corners of the toilet paper up into a mini package." Phoenix strolled over. "It looks like a little sack of flour for dolls. So cute." I glanced over at Birdie, who was busy decorating her rocket with perfect stars. "So they're fuel packets," I said. "The baking soda mixes with the vinegar to form a chemical reaction that changes the internal pressure to make the rocket go up into the sky." "Exactly," said Tala. "You got it!" She did her happy dance. The twist, kick, twirls, then claps and snaps. I did it, too. Because I really wanted to feel upbeat. "Happy dance!" we both cried. "We have to make our rocket launch extra happy," I said, hoping that Birdie would hear me and maybe it might start to nudge a smile out of her. Memito tossed up his rocket and caught it. "If you want it to be fun, you're going to need snacks."

“TP是必不可少的，”杰里米说，他把纸卷顶在头上。 “尤其是因为面包卷可以做成漂亮的帽子。” “哈哈，”我说。“卫生纸是用来装小苏打的小燃料包的，”塔拉说着，扯下一张纸。 “你把一汤匙小苏打放在一个正方形的中间。 然后剪下一根绳子，把厕纸的四角绑成一个迷你包。” 凤凰走过来。“它看起来像一小袋装娃娃的面粉。 太可爱了。”我瞥了伯蒂一眼，她正忙着用完美的星星装饰她的火箭。 “所以它们是燃料包，”我说。 “小苏打与醋混合，形成化学反应，改变内部压力，使火箭升空。” “没错。”塔拉说。“你说对了！”她高兴地跳起了舞。 扭动，踢腿，旋转，然后拍手和折断。 我也这么做了。因为我真的很想感觉乐观。 “快乐的舞蹈！”我们都叫道。 “我们得让我们的火箭发射格外开心，”我说，希望伯蒂能听到我的话，也许这会让她露出一丝微笑。 梅托掷出他的火箭，接住了它。 “如果你想让它变得有趣，你就需要零食。”

"I was thinking we could make snow slushies," I said. "Too cold." Grimacing, Memito shook his head. "I was thinking more like going to Brewster's Coffee Shop. They have Bunsen burners where you can roast marshmallows and make s'mores." He licked his lips. "Melted chocolate, marshmallow, and graham crackers. I'm getting hungry just thinking about it. Do you think Ms. Daly will let us go there after the rocket launch?" "Maybe," I said. "Will you ask?" Memito put his hands together. "It's your idea," I said. "You should get credit." "I don't care about credit. I just want to go to Brewster's. And she's more likely to say yes if you ask. Please," he said. "Yeah, Kate," said Jeremy. "You know how much Ms. Daly loooooves you." I shot him a look. Then I proceeded to march toward Ms. Daly, who was still in the back of the lab going through our supplies. As I walked on the tile floor, Memito cried, "Kate, stop!" "What did I do?" I asked. "You were about to step on a crack. Which would, you know, break your mother's back. And your mom is the principal." I whipped around and stared at him. "You don't believe that, do you?"

“我在想我们可以做雪水，”我说。 “太冷”。梅托做了个鬼脸，摇了摇头。 “我更想去布鲁斯特咖啡店。 他们有本生灯，你可以在那里烤棉花糖和做s'mores。” 他舔了舔嘴唇。融化的巧克力、棉花糖和全麦饼干。 光想想我就饿了。 你觉得火箭发射后戴利女士会让我们去那里吗？”“也许吧，”我说。 “你会问吗？”梅托双手合十。 “这是你的主意，”我说。“你应该得到表扬。” “我不在乎信用。 我只想去布鲁斯特酒吧。 如果你问她，她更有可能答应。 求你了，”他说。“是的，凯特，”杰里米说。 “你知道戴利女士有多爱你。” 我看了他一眼。然后，我继续向她走去。 戴利，他还在实验室后面翻看我们的补给。 当我走在瓷砖地板上时，梅托喊道：“凯特，停下来！”“我做了什么？”我问。 “你差点踩到裂缝。 那样的话，你知道的，会伤到你妈妈的背的。 你妈妈是校长。” 我猛地转过身来盯着他。 “你不相信，是吗？”

"Pretty much. Sort of. Yeah. Anyway, the rocket launch is on the thirteenth, so I don't want to make it worse." "What are you talking about?" I said, starting to panic. "We're having the rocket launch the weekend before winter break. Which is far away." Glancing up from her clipboard, Ms. Daly said, "Actually, Kate, Saturday the thirteenth is the last Saturday before winter break. That's when we agreed to have the rocket launch." My throat tightened. I guess I hadn't checked the calendar. The thirteenth was Liam's birthday party. At eleven a.m., just like the rocket launch! "What am I going to do?" I shrieked. "That's the same time as my brother's birthday party!" "I guess you can't do rockets with us," said Birdie. No. That couldn't happen. I just had to figure out a way to do both!

“差不多。排序的。是的。 总之，火箭发射是在13号，所以我不想把事情搞得更糟。” “你在说什么？”我说，开始恐慌起来。 “我们将在寒假前的那个周末发射火箭。 那是很远的地方。”她从写字板上抬起头来瞥了一眼。 戴利说：“实际上，凯特，13号星期六是寒假前的最后一个星期六。 那时我们就同意发射火箭了。” 我的喉咙发紧。我想我没有查日历。 第十三次是利亚姆的生日派对。 上午11点，就像火箭发射一样！“我该怎么办？”我尖叫起来。 “那和我哥哥的生日聚会是同一时间！”“我猜你不能和我们一起做火箭，”小鸟说。 否。这是不可能发生的。我得想个办法两全其美！
