SOUNDBITE (Chinese): CHEN DONG, China's Shenzhou-14 astronaut 3. various of the capillarity effect experiment STORYLINE: How does the capillarity effect work in space? Take a glimpse of the experiment conducted by Chinese astronauts. This is part of the third live class from China's space station held Wednesday. SOUNDBITE (Chinese): CHEN DONG, China's Shenzhou-14 astronaut "In the thinnest tube, the liquid rises first and reaches the top quickly. The process will take more time in the other two tubes. Unlike the experiment on Earth, in the microgravity environment in space, the surface tension of the liquid is much more obvious. This will drive the liquid to continuously rise and eventually reach the top of the tubes. Now the liquid in the thickest tube has risen to the top, too.
