Abstract
In this Letter we study the evolution of a two-dimensional soap froth. We present experimental evidence for the existence of a limiting scale-invariant distribution of the number of sides in a bulk froth at long times. We also discuss the apparent failure of the hypothesis that all internal angles in a froth are 120° and the absence of many-sided bubbles at long times. We also suggest a mechanism to explain the observed exponent describing the rate of area growth.Keywords
