This is a lesson about space taught by astronauts to Chinese primary school students. There are no deep questions but it is very interesting. I don't know what you are arguing about.
This is a Chinese astronaut giving a lesson to the children of the earth in space, but it seems that we adults find it more interesting.😂
On Earth, due to gravity, when a candle burns, hot air rises and cold air falls, so the flame takes on a cone shape. In space, due to zero gravity, the gas spreads in all directions, so the flame takes on a spherical shape.
Man I can't praise more for those video. This is what will sparkle and ignite the flame of science to young generation.
The number of armchair scientists here who seemingly believe they have a better understanding of physics than those involved in conducting this experiment is hilarious

I love this, every nation, every new astronaut marvels at the same things, simple physics experiments, I fully expect to see them playing with water bubbles next. They did the water bubbles first 1 year ago.
The biggest drawback of the internet is that it gives ignorant and foolish people the opportunity to irresponsibly express their delusions.
They made their own space station and they are on it. This is the biggest thing!!
Since there is no up and down from space. The flame went in every direction which formed a spherical shape. That's crazy to know.
Chinese astronauts are very cool! thank u for the video!
looking at the comments its only Americans that are offended that Chinese scientists make classroom videos for Chinese kids in grade school. How dare the Chinese stimulate STEM >:(
Pretty neat, never seen this before. The candle almost suffocates in its own exhaust.
无意冒犯，但这里的评论很有意思。这也许颠覆了我的认知：大多数西方成人的科学常识，比不上中国小学生。
Hot air doesn't rise in microgravity. That's why the flame is a sphere.
Love all the china hating comments.
Man all of the flat earthers and people who think space travel is fake are going to have a tough time with this one. They'll just have to blurt out "That's just CGI!" like they always do.
我喜歡所有批評中國技術的留言 偉大的美國發射火箭失敗無數次沒有人提到 中國失敗一次被無限放大。這就是中國飛躍式發展的原因，因為只能成功不能失敗！ 中國的技術或許在30年前是在進步階段，但今日的中國，很多技術連偉大的西方國家也沒有，歡迎到中國親眼看看而不是在家中用手機在網上批評中國的成功。
In zero gravity, there is no convection to drive combustion so the gasses have to diffuse through the wall of flame. Early Apollo designs used 100% Oxygen in the capsule with the understanding that lack of convection would limit any fire. But they still used 100% Oxygen during ground tests with gravity and tragically killed the crew of Apollo 1.
As long as the air breathing in the space station is about the consistency on Earth, we don't need much concerning of an explosion.
