  text: The Leidenfrost effect occurs when a liquid or stiff sublimable solid near
    a hot surface creates enough vapor beneath it to lift itself up and float. 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 "dynamic Leidenfrost effect." 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.
