Using interferometric imaging, we find different behavior for a levitated hydrogel sphere. Curvature inversion is observed briefly just after deposition, but quickly gives way to a steady state with no inversion. We show the essential role of vaporization in shaping the underbelly of the hydrogel, where changes due to direct mass loss are more significant than the balance of vapor pressure and elastic forces."}],"scopus_import":"1","fulldoi":"https://doi.org/10.1103/m7gr-2t6j","type":"journal_article","arxiv":1,"month":"05","status":"public","OA_type":"hybrid","intvolume":"       113","citation":{"apa":"Diaz Melian, V.
