"Witrynasure. The drop can follow two successive deformations se-quences prior to impalement. First, the fakir drop remains on top of the asperities of the rough surface and increases its curvature as the drop evaporates. Then, impalement is locally nucleated by a defect and lead to the growth of a partly impaled region below the drop where the liq- " - Impalement of fakir drops
