头脑风暴，英语怎么说？

Jessica在北京学汉语，她的中国朋友要是遇到了不知道用美语怎么说的词，就会来请教她。今天是逸华要问的：头脑风暴。
Jessica: Yihua! your presentation was awesome! I'm really impressed!
YH: 谢谢你 Jessica! 做得好，可不是我一个人的功劳！我们小组成员坐下来，来了一次头脑风暴！所以演示才这么成功。
Jessica: 头脑风暴？What's that?
YH: 就是大家坐下来一起讨论，集思广益呀！
Jessica: Oh! I think I know what you are talking about! You guys had a brainstorming session.
YH: Brain, b-r-a-i-n, 大脑； storm, s-t-o-r-m, 风暴。加在一起，brainstorm 就是头脑风暴喽！
Jessica: Exactly! Brainstorm basically means to put your heads together in order to come up with good ideas.
YH: put someones' heads together，把头放在一起！引申出来就是集思广益。就像中文里说的，三个臭皮匠，赛过一个诸葛亮。
Jessica: That's right! 对了，吴琼的生日快到了，Let's put our heads together and figure out what we can give her for her birthday.
YH: Good idea! 我知道，吴琼特别标新立异，所以啊，这生日礼物也得有创意才行。
Jessica: I know how picky she can be... But we can do it! Let's think outside the box and see what we should get him.
YH: Think outside the box? 到盒子外面去找？
Jessica: It basically means to break out of your normal ideas and be creative.
YH: 这个说法形象！Think outside the box! 跳出条条框框去想，就是有创意。集思广益，一定能找到有创意的想法。
Jessica: There you go! Now tell me what you've learned today!
YH: 第一，头脑风暴叫做：brainstorm；
第二，集思广益，可以说：put ones' heads together；
第三，创造性思维，叫think outside the box。
