Morphological clues to wet granular pile stability : Abstract : Nature Materials
When a granular material such as sand is mixed with a certain amount of liquid, the surface tension of the latter bestows considerable stiffness to the material, which enables, for example, sand castles to be sculpted

水の表面張力が砂を支える。そうか、こういうすごくシンプルなことさえ、予測しようとすれば大変なんだよね。これが地すべりの解明につながったりするんだろうなあ。
