13、到舱体就会飘到半空中，咳嗽一声就有可能后退好几步。,在宇宙飞船里走路更有趣。人稍一用力碰到舱体就会飘到半空中，咳嗽一声就有可能后退好几步。为了能平稳地走路，航天员都穿鞋底带钩的鞋子，好牢牢地钩住带网格的地板。,洗澡,在宇宙飞船里洗澡可不是一件容易的事，从喷头喷出的水总是漂浮在空中。为了解决这个难题，科学家把淋浴室做成一个密封浴桶，或是一个密封浴罩，在淋浴室下边安装吸管，它可以把喷头喷出来的水朝一个方向吸。另外，宇航员还需要把双脚固定起来，否则水一冲，就得翻跟头。,这是一种特殊的淋浴器。,18 太空生活趣事多,睡觉,喝水,走路,洗澡,太空生活是如此有趣，亲爱的同学们，请说一说你收集到的太空中还有哪些趣事。,拓展：,太空授课.mp4,如果现在你是一名宇航员，请你向大家介绍你在太空的生活。,大家好，我是太空宇航员（ ），要想在太空安稳的睡觉，我必须( ）；要想在太空喝水，我必须( ）；要想在太空平稳的走路，我必须( ）；要想在太空洗个澡，我必须( ）。,你看，在太空中生活，是不是很有趣？,
