We study the dynamics of the meniscus rise of a liquid contained in a narrow gap between a flexible film and a solid wall. We show that the meniscus rises indefinitely expelling liquid from the gap region, and that the height of the rising front h(t) increases with time as , while the gap distance e(t) decreases as . These results are consistent with the experiments of Cambau et al. (EPL, 96 (2011) 24001).
