Today, my mother and I went to Hangzhou Science and Technology Museum. When I got to the door, there was a sea of people, so I couldn't squeeze in. Fortunately, the tour guide bought us tickets in advance.

On the first floor, we saw the ocean, the blue earth and the moon, and many, many magical things. I wanted to play spacewalk, but there were too many people waiting in line. On the second floor, I saw the magic door. As long as I answer the question correctly, the door will open, we can get in and out, and finally we can get out of the maze. We also watched the science corridor, robot performances and so on. On the third floor, I practiced running, long jump, spinning windmill and so on. Time is limited, and there are still many things to play. My mother said to come back when I had time. I like the scientific secrets of the Science and Technology Museum very much.
