Bonus 你知道嗎
Taipei 101 has a big steel ball that acts like a giant pendulum. It counteracts movements of the building that could be caused by earthquakes or high winds.
台北101摩天大樓內設置了一個巨大鋼球，其作用像是一個巨大的擺錘，用來減緩建築物因地震或是強風所引起的晃動幅度。

Further ideas 進階點子
Try shaking the cardboard up and down. How do the rings react now? When the rings move, are they always the same shape? How about if you shake the cardboard back and forth? Try making some more rings out of stiffer paper. Add them between the first set of rings. How are the two sets different?
試著上下搖晃硬紙板，看看這些環狀物的反應是如何？當環狀物移動時，它們的形狀是否都保持不變？如果來回搖晃紙板，又會有什麼變化呢？試著用較硬的紙張多做一些環狀物，並將它們放到第一組環狀物間。這兩組環狀物有什麼不一樣的反應呢？
Science Journal 科學日誌
What do you know about earthquakes? In what directions do they make the ground move? How do your "buildings" react to earthquakes? Is the reaction always the same? Why do you think that is? Do you think you feel an earthquake more if you are in a short building or a tall building? Is that always true?
你對地震了解多少？地震的搖晃方向是如何？你做的「建築模型」對地震反應如何？反應總是都一樣嗎？你為什麼這麼覺得？你覺得地震在矮的建築物裡感覺比較大，還是在高的建築物裡感覺比較大？真的總是這樣嗎？
