BYU mechanical engineering professors Julie Crockett and Dan Maynes study superhydrophobic surfaces, or surfaces that are extremely difficult to get wet. In layman’s terms, it’s the most extreme form of water proof. In their lab they’re analyzing how water beads up or bounces off the superhydrophobic surfaces they are creating by etching microscopic ridges or posts onto CD-sized wafers.
