Walking into the museum, there is a bright hall in front of you, and colorful ribbons are hung on the top of the hall, which is so beautiful. Robots as tall as adults perform on the piano. It's a little low, but it's nice. There are time tunnels, space travel, simulated worlds and space shopping. ...
I found the name "just visiting" very interesting as soon as I named it. Time tunnel is a circular pipe. Yao and I walked hand in hand through this horrible tunnel, surrounded by red, green and yellow dots, which made me dizzy. Walking in it is like falling down, and the body seems to rotate involuntarily with the surrounding walls. How interesting! Although it was only a few seconds, it impressed me deeply.
Then we played with sound waves and saw it. Yao and I shook the rope and twisted the button. I saw the rope swinging in wavy lines. Oh, that's what invisible ultrasound looks like. This time, I opened my eyes. Later, we played many projects. I'll believe that when I see it. If you have time, please visit it yourself.
I visited the Beijing Science and Technology Museum today, which increased my knowledge and was really rewarding.
Sorry, that's all I found.
