Abstract
A film of water deposited onto a hydrophobic glass surface is metastab le and dewets the surface by nucleation and growth of a dry spot. For a film thickness of the order of e approximate to 500 mu m, the spot g rows with a constant velocity, of the order of 20 cm s(-1). The spot i s surrounded by a rim which collects the liquid and by waves that prop agates at a velocity comparable to the rim velocity: the rupture of th e film is inertial and is coupled to capillary waves.
