A computational technique to analyze how water vapor condenses on a surface patterned with an array of tiny pillars has just been developed. Calculations carried out using this technique reveal that water droplets preferentially form either on top of the pillars or in the gaps between them, depending on factors such as the height and spacing of the pillars.
