In the MicroExplorers club we studied how water reacts with various structures in nature. We looked at elephant ear plant and how its structure makes it super hydrophobic (really afraid of water). This is called the lotus effect. See previous posts about the students discoveries and the lotus effect.
Following the lotus effect investigation, one of my students wondered if Coco, our class gecko, also had super hydrophobic skin since water seemed to roll off of him whenever we sprayed the cage. Coco agreed to allow us to spray him with water and we found that his skin is super hydrophobic. It even maintained its super hydrophobicity after it was shed.
