The second lesson of "Tiangong Classroom"
The lecture will officially begin today (March 23) afternoon
Shenzhou XIII crew astronauts
Zhai Zhigang, Wang Yaping, Ye Guangfu
Space lectures on the China Space Station
Space experiments, full of dry goods
Come and review
Space "ice and snow" experiments
Looks like an "ice hockey" is actually a "hotball"
In the "four seasons like spring" Chinese space station
Wang Yaping made a crystal clear "ice ball"
- Crystallization of liquid balls
What's the principle behind it? Poke the video
Liquid bridge demonstration experiment
Build a bridge with liquids in space
Ground gravity environment
The surface tension of the water is insignificant
So in the microgravity environment of space
How strong is the surface tension of the liquid?
Watch the astronauts build a bridge with liquid
In the space station
Do water and oil naturally layer?
On the ground, water and oil are mixed and naturally delaminate
Oil on top, water on bottom
So in the space station
The answer is no
Watch the video to see why
The ice pier is in space!
Become a small teaching assistant of "Tiangong Classroom"
Space parabolic experiments
Here comes a special teaching assistant: the ice pier
Throw ice piers in space
Will it fall down like on the ground?
Give it a try and you'll find out!
Many netizens said
"Envy the retirement life of the ice pier"
What is it like to shed tears in space?
Heaven and Earth Interactive Session
A classmate asked a question
What is it like to shed tears on a space station?
It is stretched very long in the corner of the eye like jelly
Or did it jump out and become one by one?
Let's see what the astronauts have to say
After watching these experiments, netizens directly called out magic
I am full of yearning for space
"The train of thought has opened!"
"The space physics class was so interesting"
