小时候玩纸飞机的时候,我们都要朝它的尖头处哈一口气,听大人说这样能让纸飞机飞得更高更远。是这样吗?我都上初三了,学到的科学知识好像还是不能解答这个问题。 When we were playing with paper planes as a child, we all had to take a breath toward its pointed tip. Listening to adults said this would allow the paper plane to fly higher and further. Is it? I am on the third day, learned science knowledge still can not answer this question.
