Fun experiments A bridge of water It's hard to build a "bridge" with water on Earth. But in the space station, with little gravity (重力), it's quite easy! Wang Yaping first made two water balls on two plates, and then she tried to let them touch each other. Next, the plates were gently pulled apart, and the water between them didn't break. It became a "bridge"! Oil-water separation If we mix oil and water in a bottle on Earth, they will quickly separate because they have different densities (密度). Gravity brings the water down while the oil stays on top. However, if you do this in the space station, with little gravity, the oil and water will blend (融合) together. |
Students talk about the lecture | |
![]() Zhang Kexin, 13, Beijing | I did the "oil-water separation" experiment years ago, on Earth, of course. So, I know that the oil and water will separate easily. But they don't separate in the space station. That is amazing!The lecture ignited my passion (热情) for going to space one day. I want to study how to grow vegetables and fruits in space so that astronauts will never need to worry about food. |
![]() Zhang Hangming, 14, Tianjin | The experiments really shocked me!They helped me better understand the knowledge behind them. Also, it's the interesting experiments that made me fall in love with science. From now on, I will study hard and have fun, since studying can be so fun! |
