在某些准静态过程中，当干泡沫中的面的面积接近于零时，Plateau的规则规定必须存在不稳定性。这比一般想象的要微妙得多。我们认为，它通常是先发制人的，也就是说，不稳定性出现之前，一个不稳定的多重顶点形成。模拟Plateau线框实验的实验和计算支持了这一观点。
When the area of a face in a dry foam approaches zero in some quasistatic processes, Plateau's rules dictate that there must be an instability. This is more subtle than generally supposed. We argue that it is generally pre-empted, that is, the instability arises before an unstable multiple vertex is formed. Experiments and calculations which simulate Plateau's wire frame experiments support this view.
