第四步 妙笔成篇 If I went to travel in space, there would be a problem I might be faced with: how to eat and drink in outer space. I would have to take all my foods with me if I went to space travel, but in outer space, the gravity is so weak that the food will float around if it is solid. I must make sure that it is specially made as liquid space food. It could be put in a tube and then I would be able to suck it more easily. Perhaps I would use a straw to eat it. It can prevent the food from floating away. Only in this way would the problem be solved. I might have a happy visit to space in that way. I will have a try in time.
