Have you ever had the misfortune of having your product – whether it is a brand new shiny smartphone, a chic headphone, or your survival torchlight – go kaput on you due to exposure to moisture? Perhaps, you’ve had one of your devices get spoilt.

I believe you must have noticed during the summer months, beads of moisture forming on leaves early in the morning – that is before sunrise – due to dews. Did you stop to think about why the water didn’t soak into the plants? Or what property of the leaves that makes it possible for the water to form those small balls of moisture and roll of the surface?
I am curious also about the behavior of these materials when placed under wet conditions and decided to investigate. The result is this article.
