“完了，已經被出題老師看到了……”物理老師：“謝謝，已收藏~”

近日，有同學在打籃球間隙休息時，為了不讓籃球滾動，把四個籃球摞在一起，卻沒想到四個籃球一起“長腳”了！

中科院物理所評論道：“很好的sp3雜化軌道?！?/p>

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".

據了解，原子軌道在成鍵過程中，有一種增強成鍵能力，使體系更加穩定的趨勢。受這一趨勢的驅動，出現了雜化軌道。與未雜化的s軌道或p軌道相比，sp3雜化軌道在成鍵時能夠更有效地重疊，生成的共價鍵更加穩定。

有網友表示：“我有某種不詳的預感，不久就會出現在卷子上?！?/p>

還有網友表示：“已經做到這個題了?！?/p>

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.

除了無意間“觸發”的“壓軸題”，還有的同學主動創造物理“壓軸題”。

近日，有同學用13把椅子+1張桌子搭出了懸浮感拉滿的“力學奇跡”。

評論區熱鬧非凡，中科院物理所率先趕來：“請給出圖中結構的受力分析。”

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.

物理老師：“謝謝，已收藏！”

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

還有不少同學分享起了自己創造的“力學奇跡”。

一支筆能寫作業，一摞筆能“蓋大樓”，一把尺子三支筆，還能做出巧妙的平衡裝置。

還有老師拍下學生純手工打造的“高檔機械裝置”，網友紛紛驚嘆：“他居然會用液壓與氣壓傳動！”

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.

同桌隨手制作的“百變線球”令人目瞪口呆。

草稿紙+膠水=能開的鎖。

還有同學用極簡版工具給課桌桌肚安排上了“卷閘門”。

你的學生時代里有哪些“腦洞”大開的瞬間？
