In contrast, vaporizable soft solids, e.g., hydrogels, have been shown to exhibit persistent bouncing - the elastic Leidenfrost effect. By carefully lowering hydrogel spheres towards a hot surface, we discover that they are also capable of floating. The bounce-to-float transition is controlled by the approach velocity and temperature, analogously to the &quot;dynamic Leidenfrost effect.&quot; For the floating regime, we measure power-law scalings for the gap geometry, which we explain with a model that couples the vaporization rate to the spherical shape. Our results reveal that hydrogels are a promising pathway for controlling floating Leidenfrost objects through shape."}],"volume":121,"date_updated":"2021-01-12T06:49:27Z","publist_id":"7927","oa_version":"None","type":"journal_article","doi":"10.1103/PhysRevLett.121.048001","_id":"126","publication":"Physical Review Letters","language":[{"iso":"eng"}],"acknowledgement":"We acknowledge funding from the Netherlands Organization for Scientific Research through Grants VICI No. NWO- 680-47-609 (M. v.
