课文

Soap bubbles look magical, but they’re actually very fragile films of water sandwiched between two layers of soap molecules.

肥皂泡看似神奇，实则是夹在两层肥皂分子之间的极薄水膜。
The outer and inner surfaces pull inward due to surface tension, which keeps the bubble round and thin.

内外表面因表面张力向内收缩，使泡泡保持圆润与纤薄。
When a finger or dust touches it, that local area loses balance and the water layer drains instantly.

手指或灰尘一触即破，局部失衡导致水膜瞬间流失。
Evaporation also thins the film from within, especially in dry or warm air, making rupture more likely.

蒸发也会从内部变薄液膜，尤其在干燥或温暖空气中，更易破裂。
Adding glycerin or sugar to homemade bubble solution slows evaporation and increases flexibility.

自制泡泡液中添加甘油或糖可减缓蒸发、增强韧性。
Light bends differently through the changing thickness of the film, creating those shimmering rainbow colors.

光线穿过厚度不断变化的液膜时发生不同程度的折射，形成 shimmering 彩虹色。
Even gentle air currents disturb the delicate force equilibrium, causing early collapse before full formation.

就连微弱气流也会破坏脆弱的受力平衡，导致泡泡未完全成形便提前破裂。
Scientists study bubble physics to improve medical ultrasound contrast agents and food texture engineering.

科学家研究泡泡物理，以改进医用超声造影剂和食品质构工程。
