A copper‐rich cereal : Superhydrophobic copper particles show a very large Cheerios effect and rapidly self‐assemble into robust sheets on the surface of water. These sheets can support objects (including water drops, see photo) placed on them, even though the irregular geometry of the particles means that they contain macroscopic holes.
