# chem: how to quickly wrap droplets with a splash to stabilize emulsions

<< Whether an object has a regular or irregular shape, wrapping it with a thin film can be challenging >>

<< The quick and simple solution Kumar [Deepak Kumar] has found is a huge advance, and once he mastered it and identified the most important parameters, he found he could get adventurous and make different shapes. "We show that we have made cubes and a tetrahedron, for example" >>

<< If you want to add complexity, you could put a layer or a pattern on the inside of the wrapping, or you could add a window to make it slightly leaky. Once you know how to do the technique, it's not fussy. >>
