The Stone Hidden by the Volcano- 適合中高級的英語短篇故事

Morning clouds drifted apart above the playground, leaving clean light over the science tables. Darius set his model volcano in the centre of a blue tarp and wiped clay from his fingers. The cardboard cone had been painted by hand and covered with damp soil for extra texture. Warm air carried a faint smell of vinegar, and bubbles fizzed inside a hidden flask under the cone. A small pressure gauge, borrowed from the physics room, jutted out near the base, its needle hovering at zero.

He planned a showy fountain, yet the first switch produced only a tired hiss and a thin ribbon of foam. The needle barely moved, so he tightened a stopper with the edge of his thumb and added another spoon of baking powder. When he tried again, the gauge jumped, then froze; something blocked the narrow tube leading toward the crater. He shook the cone gently, hoping loose grit would slide aside, but the blockage stayed in place. He glanced at the surrounding environment, checking that no other projects were too close. A sudden pop sounded beneath the tarp, and warm liquid sprayed through a hairline crack near the bottom panel.

Escaping foam washed away soil and uncovered a smooth stone figure the size of his thumb, shaped like a silent guardian. He crouched, turned the model sideways, and let pressure escape until the gauge dropped to a safe number. The cardboard walls sagged, yet the small figure remained upright, as if keeping watch over the messy experiment. He had practised the demonstration many times at home, but nothing in that experience prepared him for this debris. The cone now leaned against spare boards, and pinkish foam pooled around the tiny stone figure.

操場上方的雲層散開，透出的陽光照在科學展的桌子上。達利烏斯把他的火山模型放在藍色防水布中央，並抹去手上的黏土。那個紙板錐體是他親手塗色，再覆上濕土讓表面更像真實地形。溫暖的空氣帶著淡淡的醋味，錐體下方的隱藏燒瓶裡泡沫嘶嘯。借來的微小壓力計突出在底部，指針停在零的位置。

他打算噴出壯觀的泡沫，但第一次開關只發出疲憊的嘶聲，流出細細的白沫。指針幾乎沒動，他便用拇指邊緣把塞子擰緊，又加了一匙發泡粉。第二次嘗試，壓力計猛然一跳後就停住；連接火山口的細管被什麼堵住了。他輕輕搖動錐體，希望鬆動的細砂能滑開，但堵塞依舊。他環顧四周的環境，確認其他作品沒有靠得太近。突然，一聲輕爆響在布下傳出，溫熱液體從底板的微裂縫噴射而出。

逸散的泡沫沖走土層，露出一枚拇指大小的光滑石像，形似無聲守護者。他蹲下身，把模型側轉，放走多餘壓力，直到指針降到安全範圍。紙板壁雖然下陷，那小石像卻依然直立，仿佛在守望這場凌亂實驗。他在家練習過無數次，卻從未有這種經驗帶來的意外驚喜。此刻錐體斜靠在備用木板旁，粉紅泡沫正圍著小石像匯聚。
