Outline
A compound drop consisting of a water core and a silicone oil shell impacts on a hydrophilic glass substrate. Remarkably, the oil shell acts as a lubricating layer upon impact, promoting either full or partial rebound of the inner water drop from the glass substrate, even when this glass substrate is completely hydrophilic. Additionally, a cavity is formed in the center of the spreading water core. When the water core retracts, this cavity collapses and a sharp vertical oil jet is ejected at high speed.

The diffusion-driven growth of a foam ball in supersaturated liquids. Under normal gravity conditions, a bubble cloud grows by diffusion, however this process is interrupted after a few milliseconds when the bubble cloud starts a buoyancy-included rising motion. On the other hand, under micro-gravity conditions bubbles grow by pure diffusion.
We want to express our thanks to the judges for the awards.
