Interactions of colloidal particles can be tuned over a wide range. Truly long-range interactions (like gravity) are possible through solvent flow. In this work we demonstrate that colloidal ion reservoirs produce such flows that are well-described as a conservative potential, predicting the dynamics and structure of clusters of a few particles ("molecules").
