🦎 壁虎不用膠水，是怎麼在牆壁和天花板上行走的？

How do geckos walk on walls and ceilings without glue?

🧠 好奇問題：壁虎腳上明明沒有膠水也沒有吸盤，為什麼可以穩穩貼在牆壁和天花板上走動呢？

🎧 這一集在聊什麼：這集節目要帶大家發現壁虎腳掌的秘密，原來牠們腳底長著數十萬根微細毛髮，末端還分出上百個更小的微細分叉。當這些細毛緊緊貼在物體表面時，彼此產生的微小吸引力合在一起，就能支撐壁虎的體重，不需要黏液就能牢牢抓住牆面。科學家還模仿這個特殊的結構，做出不用膠水也能黏住物體、而且能自我清潔的神奇人造材料。

👦👧 適合誰收聽：適合國小生收聽，也很適合爸媽陪孩子一起聽、一起討論。
