G.W. is grateful for the financial support from China Scholarship Council (201704910870) and postgraduate research group in Newcastle University. We also thank the anonymous reviewees, who corrected a couple of faulty analysis in our initial manuscript and helped us rule out more in-depth deformation analysis.

N2 - We derive a model entirely from first principles to explain the Leidenfrost self-propulsion phenomenon in a quantitative way, where the deformable nature of the liquid has been taken into account. Experiments show a good agreement with our model, suggesting this model supersedes the limited scaling analysis previously given in the literature. Our annular ring design enables liquid droplets to reach high terminal velocities, up to 0.42±0.04 m/s, which is potentially beneficial to energy harvesting and flow chemistry applications.
