在许多粘性液体中产生的气泡上升到液体-空气界面，并在那里停留一段时间，然后爆炸和消失。这种气泡的寿命取决于将气泡与大量空气分离的半球形液体膜的变薄动力学。在这里，由两个单独的润湿板所限制的气泡的寿命进行了实验研究，间距，粘度和气泡尺寸的变化。虽然薄膜不是半球形的，但它具有非平凡的形状，一个相对简单的流体动力学模型解释了观测结果。
Air bubbles created in many viscous liquids rise up to the liquid-air interface and stay there for a while before exploding and disappearing. The lifetimes of such bubbles are governed by the thinning dynamics of the hemispherical liquid film separating the bubble from bulk air. Here, the lifetime of bubbles confined by two separated wetting plates is experimentally studied as the distance apart, viscosity, and bubble size are changed. Although the film is not hemispherical but takes a nontrivial shape, a relatively simple hydrodynamic model accounts for the observations.
