“完了，已经被出题老师看到了……”物理老师：“谢谢，已收藏~”

近日，有同学在打篮球间隙休息时，为了不让篮球滚动，把四个篮球摞在一起，却没想到四个篮球一起“长脚”了！

中科院物理所评论道：“很好的sp3杂化轨道。”

Students across China have gone viral for turning everyday classroom objects into creative, physics-inspired contraptions.

During a basketball break, several students stacked four balls together to keep them from rolling away — only to watch them unexpectedly move in unison. The moment prompted a witty response from the Institute of Physics at the Chinese Academy of Sciences, which joked that it was "a perfect example of sp³ hybridization".

据了解，原子轨道在成键过程中，有一种增强成键能力，使体系更加稳定的趋势。受这一趋势的驱动，出现了杂化轨道。与未杂化的s轨道或p轨道相比，sp3杂化轨道在成键时能够更有效地重叠，生成的共价键更加稳定。

有网友表示：“我有某种不详的预感，不久就会出现在卷子上。”

还有网友表示：“已经做到这个题了。”

Online reactions quickly followed. Some users predicted that such scenarios could soon appear in exam papers, while others said they had already encountered similar questions.

除了无意间“触发”的“压轴题”，还有的同学主动创造物理“压轴题”。

近日，有同学用13把椅子+1张桌子搭出了悬浮感拉满的“力学奇迹”。

评论区热闹非凡，中科院物理所率先赶来：“请给出图中结构的受力分析。”

In a separate case, a student used 13 chairs and one table to construct a seemingly gravity-defying structure, sparking heated discussion in the comments section. The institute again joined the conversation, humorously challenging viewers to analyze the forces acting on the setup.

物理老师：“谢谢，已收藏！”

A physics teacher also weighed in, saying the example had been saved for future teaching use.

还有不少同学分享起了自己创造的“力学奇迹”。

一支笔能写作业，一摞笔能“盖大楼”，一把尺子三支笔，还能做出巧妙的平衡装置。

还有老师拍下学生纯手工打造的“高档机械装置”，网友纷纷惊叹：“他居然会用液压与气压传动！”

More students have since shared their own creations, ranging from delicate balancing setups made with pens and rulers to intricate handmade devices resembling mechanical systems powered by air and fluid pressure.

同桌随手制作的“百变线球”令人目瞪口呆。

草稿纸+胶水=能开的锁。

还有同学用极简版工具给课桌桌肚安排上了“卷闸门”。

你的学生时代里有哪些“脑洞”大开的瞬间？
