Work lead by Lorenzo Botto and Rafael Castrejón-Pita has been featured in a piece on Physics Today.

Water-repellent clothing is designed to keep water droplets out while letting humidity escape.Hydrophobic fabric meets both requirements, but in striking a balance between them, it fails to repel water completely. When and how that failure occurs is the subject of a new study led by Lorenzo Botto and Rafael Castrejón-Pita at Queen Mary University of London. The researchers treated nylon fabric to make it hydrophobic, and then they used a high-speed camera to record how the droplets—made of water and glycerol—behaved as they struck the fabric.
