在「天鵝湖」第三幕，黑天鵝成功完成那似乎無止境的連續旋轉，以一個腳尖上下移動，不停不停地旋轉了 32 次。這個叫 單足趾尖旋轉／fouettés 的動作是怎麼可能做到的？ Arleen Sugano 闡明了這個著名芭蕾動作的物理原理。

The legendary fouetté from "Swan Lake"—32 rapid-fire spins on one foot—looks like sorcery but relies on precise physics. Each turn demands a careful balance of momentum, torque, and the strategic movement of arms and legs. The dancer’s elevated leg acts as a storehouse for momentum, transferring energy back and forth to keep her spinning. What appears effortless on stage is actually a masterclass in conserving angular momentum against the drag of friction.
