Visits are free, except for the children's area (children's area is suitable for children under 8 years old). Every current limit written in the public account is reserved from the public account before going. But no one checked the QR code of my appointment when there were many people (it is estimated that it will be checked). You must wear a mask when you enter, and the bag must pass the security check. There is a map at the door to get one. There is a reminder that it is forbidden to eat in the exhibition hall. At noon, there are box lunches and various snacks at the gate. The box lunch is 15 yuan apiece and the amount of dishes is normal. The restaurant is also written on the map. But I didn't find it. On the stool in the hall, there were a lot of food at noon. The food seller said that he would let the food in (but I didn't enter, I went back to the car to eat). The items inside can be experienced for free, except for some affected by height and weight, there are prompts next to it. For example, the propeller power principle, limit the height of 140 ㎝ or more (legs short enough), weight below 100kg. The fatter one should be prepared in my heart. I *** catty, the first 15 seconds of the beginning of the squat. Although the propeller turned, I didn't move my silk. It was embarrassing and thinking quickly. Because I was too fat, I needed more power. I immediately turned on the mammoth mode. Finally, it started to move.. There are simulation tornadoes, simulation hydropower, simulation submarines, simulation lightning, etc., all kinds of small experiments that can be experienced, generally queued up for a person to be my turn, there is no feeling of wasting time. I originally planned to watch a movie, but later I didn't see something. Next time I go to see it, the price of the movie ticket is different. Write ✍🏻 next time I go.
