Wrapping with a splash: High-speed encapsulation with ultrathin sheets

Abstract

It's a wrap Whether an object has a regular or irregular shape, wrapping it with a thin film can be challenging. Kumar et al. released droplets of oil above thin polymer sheets floating on water (see the Perspective by Amstad). With sufficient impact force, the polymer wrapped around the droplet with near perfect seams. The shape of the resulting enclosed drop depended on the shape of the sheet initially placed at the air-liquid interphase. Science , this issue p. 775 ; see also p. 743
