11 Something to Do with Pressure

CHAPTER ELEVEN SOMETHING TO DO WITH PRESSURE Boyle's law (proper noun). This law says that the pressure of a gas goes up as the volume of its container gets smaller. Just like if you squeeze one part of the balloon (like a dog leg or monkey tail), the size of the balloon decreases and the pressure increases. If you squeeze the dog leg really hard, the pressure will increase so much that the balloon will explode! POP! OVER BY THE SUPPLY TABLE, Elijah and Memito were arguing about the secret material that would make our rockets really soar. And I realized I hadn't figured it out yet either. All I knew is that it had something to do with pressure. And right now, honestly, I was feeling a lot of that. "Oh, I have to do something!" I said to Birdie, who glanced back at me with a confused expression. Heading to the middle of the lab, I explained, "I've got to make an educated guess." I stopped in front of the supply table. "If all the supplies are here, one of them should be the special material," I said, looking over at Tala for

第十一章与压力有关的波义耳定律（专有名词）。 这个定律说气体的压强随着容器的体积变小而增大。 就像如果你挤压气球的一部分（如狗腿或猴尾巴），气球的大小会减小，压力会增加。 如果你用力挤压狗腿，压力会增加很多，气球会爆炸！流行!在供应桌那边，以利亚和梅托正在争论让我们的火箭真正飞起来的秘密材料。 我意识到我也没有弄明白。 我只知道这和压力有关。 而现在，说实话，我感觉到了很多。 “哦，我得做点什么！”我对伯迪说，它也带着困惑的表情瞥了我一眼。 走到实验室中央，我解释说：“我得做一个有根据的猜测。” 我在供应桌前停了下来。 “如果所有的物资都在这里，其中一个应该是特殊材料，”我说，看着塔拉

confirmation. "You're right." Tala gave a thumbs-up. "It's definitely right here." Jeremy flipped a coin into the air. The streak of purple in his blond hair flopped in his eyes. "I bet which one of you would get it right." He pointed at Memito and Elijah and then me. "I said you, Kate." "You shouldn't bet." I shook my head, but privately I felt a little happy about it. And surprised, since sometimes in the past, Jeremy wanted me to lose, whether it was a pickup game of soccer or the science fair. Memito scooped up a plastic water bottle. "How about this?" Tala shook her head. "It's essential but not a secret way to make the best rocket ever." "The nose cone? Right? That's it?" asked Elijah. "Nope," said Tala. "How about the sequins?" piped up Birdie, who was standing a bit farther away from the table than the rest of us. My heart gave a little squeeze of happiness. She sounded almost like her regular self. "Sequins are just decoration," said Tala. "Decoration is essential." I nodded at Birdie's nose cone with its glittery swirls.

确认。“你说得对。” 塔拉竖起大拇指。“它绝对就在这里。” 杰里米把一枚硬币抛向空中。 他金色头发里的那缕紫色在他的眼睛里闪烁。 “我打赌你们俩谁能做对。” 他指了指米托和以利亚，又指了指我。 “我说的是你，凯特。”“你不应该打赌。” 我摇了摇头，但私下里我对此感到有点高兴。 而且很惊讶，因为在过去，有时杰里米希望我输，无论是足球比赛还是科学展览。 Memito舀起一个塑料水瓶。 “这个怎么样？”塔拉摇了摇头。 “制造有史以来最好的火箭，这是必不可少的，但不是秘密。” “鼻锥？”对吧?以利亚问。 “不，”塔拉说。“那亮片呢？”比我们站得远一点的伯蒂尖声问道。 我的心感到一阵幸福。 她的声音听起来几乎和平常一样。 “亮片只是装饰，”塔拉说。 “装饰是必不可少的。” 我对着“小鸟”闪闪发光的鼻锥点了点头。

"Exactly. I mean, can you imagine going to a play without a set or curtains or costumes?" said Avery. "It would be so humdrum," she over-enunciated as if she were onstage. "What do you think, Kate?" asked Jeremy. "I mean about the special material?" My eyes swept over the materials. The heaps of bottles, colored paper, corks, little sequins, ribbons, and glitter for decoration. "I think it's the cork," I said. "Because it seals the bottle to build up pressure, which produces the thrust." "Good science," said Tala. "But still, no." That's when Jeremy walked to the table, picked up a roll of toilet paper, and wrapped some around his neck. "I have no clue what it is," he said. "But look at me; I'm a mummy!" "Actually, he's much more than a mummy," said Tala. "Jeremy has the answer."

“没错。我是说，你能想象没有布景、没有窗帘、没有服装就去看戏吗？”艾弗里说。 “那太无聊了，”她说得太清楚了，就好像她在台上一样。 “你觉得怎么样，凯特？”杰里米问。 “我是说那种特殊的材料？”我的眼睛扫视了一下材料。 成堆的瓶子、彩纸、软木塞、小亮片、丝带和闪闪发光的装饰品。 “我想是软木塞的问题，”我说。 “因为它密封了瓶子，从而产生压力，从而产生推力。” “好的科学。”塔拉说。 “但还是不行。”这时杰里米走到桌边，拿起一卷卫生纸，在脖子上缠了一些。 “我不知道这是什么，”他说。 “可是你看看我；我是木乃伊！”“事实上，他不仅仅是一具木乃伊，”塔拉说。 “杰里米知道答案。”
