  Although a hydrophobic microtexture at a solid surface most often reflects
rain owing to the presence of entrapped air within the texture, it is much more
challenging to repel hot water. As it contacts a colder material, hot water
generates condensation within the cavities at the solid surface, which
eventually builds bridges between the substrate and the water, and thus
destroys repellency. Here we show that both "small" (~100 nm) and "large" (~10
\mu m) model features do reflect hot drops at any drop temperature and in the
whole range of explored impact velocities. Hence, we can define two structural
recipes for repelling hot water: drops on nanometric features hardly stick
owing to the miniaturization of water bridges, whereas kinetics of condensation
in large features is too slow to connect the liquid to the solid at impact.
