Although the solid fraction was very low (∼0.02%), this surface could support a drop of water under a pressure of 234 Pa. Supporting Information Detailed facts of importance to specialist readers are published as "Supporting Information". Such documents are peer-reviewed, but not copy-edited or typeset.
