Droplet Manipulation In article number 2100178, Fernando Benito‐Lopez, Lourdes Basabe‐Desmonts, and Vahid Nasirimarekani show that the interaction between an oil‐based ferrofluid and a drop of water results in the formation of a ferrofluid ring around the drop of water. The ring behaves like a soft matter dipole, disappearing once the magnetic field is removed. The set takes the shape of a cupcake and allows precise movement of the drop on a surface, even on inverted surfaces.
