Recently, some foreign netizens raised questions about a scene in "Tiangong Classroom" and used it to question the authenticity of the space station. They even suspected that the above video was shot in a studio on Earth.

"Why doesn't the water float?" Foreign netizens were jealous again and even questioned Chinese Space Station as "fake".

Recently, some foreign netizens raised questions about a scene in " Tiangong Classroom ", questioning the authenticity of space station , and even suspected that the above video was shot in a studio on Earth.

said this for two reasons. First, why didn’t the water cup float in the weightless environment of the space station? Second, why didn’t the water in the water glass spill out?

At first glance, what this netizen said seemed to make sense, but after seeing the response from professionals, I realized that the foreign netizen was taking it out of context.

Many professional aerospace agencies responded to this. The water cup did not float because it was fixed for the convenience of teaching; the water remained in the water cup because of surface tension .

If you patiently read the teaching process of and Wang Yaping , you will not have any doubts. Because after Wang Yaping picked up the water cup, he pushed it gently with his hand, and the water cup floated in the air and started spinning.

Now, the crew of Shenzhou 14 has entered the space station to work. At this time, foreign netizens raised such doubts. I don’t know if they are unintentional or intentional.

No matter what, let’s take root in the underlying technology, follow our own path, and let others envy us!
