| - | A glass tube with a sealed top is filled with water and mounted vertically. The bottom end of the tube is immersed in a beaker of water and a short segment of the tube is heated. Investigate and explain the periodic motion of the water and any vapour bubbles observed. | + | Take a vessel and pour some granular material into it, for example, rice. If you dip e.g. a spoon into it, then at a certain depth of immersion, you can lift the vessel and contents by holding the spoon. Explain this phenomenon and explore the relevant parameters of the system. |
| - | 将一个玻璃管（顶部密封）中灌满水并垂直安装。玻璃管底端浸在盛有水的烧杯中，对玻璃管的一小段进行加热。研究并解释水和观察到的气泡的周期性运动。 | + | 取一个容器，并倒入一些颗粒状物质，如大米。如果把勺子浸入其中，并达到一定浸入深度，你就可以通过勺子举起该容器及其内部颗粒物质。解释这一现象并探索系统的相关参数。 |
