Chemistry Emulsions consist of droplets of one liquid that are held inside a second liquid, where the two liquids do not normally mix. Haase and Brujic show a simple method to make emulsions in which multiple layers of droplets can be trapped inside each other. By varying the concentrations of oil, a polar solvent, and water, they can get up to five layers of inner droplets as the ternary mixture is dripped into a water solution containing surfactant. It is also possible to fuse droplets to give larger, stabilized droplets with ordered internal structure. Angew. Chemie. Int. Ed. 10.1002/anie.201406040 (2014).
