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.","lang":"eng"}],"date_created":"2018-12-11T11:44:46Z","intvolume":"       121","publication":"Physical Review Letters","article_number":"048001 ","date_updated":"2021-01-12T06:49:27Z","quality_controlled":"1","date_published":"2018-07-25T00:00:00Z","year":"2018","day":"25","publist_id":"7927","author":[{"orcid":"0000-0002-2299-3176","first_name":"Scott R","full_name":"Waitukaitis, Scott R","last_name":"Waitukaitis","id":"3A1FFC16-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Kirsten","full_name":"Harth, Kirsten","last_name":"Harth"},{"last_name":"Van Hecke","first_name":"Martin","full_name":"Van Hecke, Martin"}],"extern":"1","acknowledgement":"We acknowledge funding from the Netherlands Organization for Scientific Research through Grants VICI No. NWO- 680-47-609 (M. v.
