Is a nanoscale hydrophobic bowl wet or dry when dissolved in water? It turns out that the answer depends on the architecture of its rim. A molecular host decorated with four methyl groups around its rim pointing inward, rather than up, has now been shown to expel water from the bowl, making it dry and sticky.
