Shenzhou 16 astronauts Jing Haipeng, Zhu Yangzhu and Gui Haichao taught space science popularization in orbit, and the three doctors took the national teenagers into the new classroom - Mengtian Experimental Module, to show the students the work and life scenes of Mengtian Experimental Module.

Afterwards, the astronauts demonstrated the spherical flame experiment, the wonderful "ping-pong" experiment, the momentum conservation experiment and the gyro experiment to the students, and interacted with the ground classroom.

In class, I learned that the flames that candles burn on the space station are approximately spherical, and the candles do not burn as fully as the ground, and the temperature of the flames is lower and blue. Subsequently, the astronauts played a "table tennis friendly match" on the space station, and when using ordinary rackets, water balls were glued to the rackets; And using a racket made of towels, the water balloon not only did not absorb, but bounced off.

The astronauts also demonstrated the momentum conservation experiment and explained the collision phenomenon of the center of mass of steel balls in microgravity. The class also reproduced the "space turn", astronaut Gui Haichao used a rotating metal gyro to turn around in space.

Five on-site classes were set up in Beijing, Inner Mongolia Alashan League, Yan'an, Anhui Tongcheng and Ningbo, Zhejiang, with about 2,800 student representatives participating in the on-site activities. At the same time, students from all over the country watched the live broadcast of "Tiangong Classroom" in real time in the classroom, and simultaneously conducted experiments to explore the fun of science.
