Green Powder in the Spinning Drum- 適合中級的英語短篇故事

A faint hum rolled from the small hand-crank rotor each time Lyra turned it. Thin metal fins inside the clear drum began to spin. The freshness of crushed mint rose through the gaps. Grant leaned closer to check the evenly cut portion of leaves resting on the turning tray. The two friends worked in the quiet observation corner. Jars, coils of copper wire, and a wide glass lens lined the shelves. Pale morning light touched the polished brass, and a cool draught brushed their sleeves. A wooden wheel, fixed below the drum, pivoted on a single steel pin. Each rotation nudged a tiny gear that counted the rounds. Grant waited beside the window, his fingers hovering with brief hesitation before adding another herb sample. The motion wanted balance, yet the added weight threatened wobble.

The moment Grant released the new leaves, the drum wobbled and a loose screw started to unwind. Lyra caught the handle before the gear stalled. She twisted her wrist the opposite way to slow the spin. The weight still dragged one side downward, while the remaining momentum pressed outward. She shifted her grip, lowering the handle and letting the wheel reel forward with shorter strokes. Grant steadied the frame by pressing two knuckles against the wooden rim. Their combined adjustment evened the orbit, though the tray now carried a thin spiral of scattered mint. A surprised puff of powder marked the unexpected twist. A hidden seed pod split under the force and painted the inner wall green. Neither of them tried to collect the dust; they only watched the drum glide at a steady pace. The cracked pod hovered against the glass. The handle drifted back and forth without another drop in rhythm.

每當萊拉轉動那只手搖轉子，輕輕的嗡鳴聲就在空氣裡流動。透明圓筒內的金屬薄片開始旋轉，碎薄荷的清新香氣從縫隙飄出。格蘭特俯身觀察放在旋轉托盤上的均勻葉片份量。兩位朋友在安靜的觀察角落裡忙碌。架子上排著玻璃罐、銅線圈和一片寬大的玻璃透鏡。清晨微光落在拋光的黃銅上，涼爽氣流拂過他們的袖口。木質輪子固定在圓筒下方，依單一鋼針支點轉動。每一次旋轉都推動一枚細齒輪計數。格蘭特站在窗邊，指尖因短暫遲疑而懸在空中，隨後放入另一份草本樣品。旋轉想要保持平衡，但新增重量開始讓圓筒晃動。

格蘭特一放手，新葉落下，圓筒便搖晃起來，一顆鬆動的螺絲開始鬆開。萊拉在齒輪停住前抓住把手。她反向扭動手腕以減慢旋轉。重量依舊拉低一側，而剩餘動能向外推。她改變握法，降低把手，讓輪子以較短的行程前行。格蘭特用兩指關節抵住木框，使結構保持穩定。他們的調整讓軌道重新均勻，不過托盤上已出現散落薄荷所形成的細螺旋。意外的粉末雲突地升起，標誌著轉折。一枚隱藏的種莢在離心力下裂開，將內壁染成綠色。他們沒有收集粉末，只是看著圓筒以穩定步調滑行。裂開的種莢停在玻璃內側。把手前後擺動，節奏再未失衡。
