Abstract
A water film (thickness e) between two hydrophobic solids is metastabl e. If contact is established (over an initial disc of radius R(0) > R , where R is a certain nucleation size), the dry path expands (up to a size R(t) at time t), and the rejected water forms a rim (of width l (t)) around the patch. We predict R(t) approximately t3/4 and l(t) app roximately t1/2. Typically, over 5 x 10(-3) s we expect R(t) approxima tely 1.6 mm.
