This study was designed to investigate the possibility of using visible surface features to decrease the amount of time a droplet remains in contact with a hydrophobic surface. Hydrophobic and superhydrophobic surfaces have long been a focus for scientists studying fluids. However, a majority of studies have focused on surfaces with hydrophobic properties rooted in their chemical makeup or other features invisible to the naked eye. In this study, the contact reduction induced by a simple needle protruding from a hydrophobic surface is investigated.
