Biomimetic replicas of superhydrophobic lotus and taro leaf surfaces can be made using polydimethylsiloxane. These replicas faithfully reproduce the microstructures of the leaves' surface and can be analyzed using contact angle goniometry, self-cleaning experiments, and optical microscopy. These simple and adaptable experiments were used to develop a novel general chemistry laboratory exercise, designed to introduce students to the current fields of materials science and biomimetics, and reinforce concepts such as intermolecular forces and surface tension.
