A reflection on the “Grotthuss mechanism” of proton transport observed in nonporous single crystals by L. R. Falvello, G. J. McIntyre, M. Tomás et al. in their Communication on page 13463 ff. The pirouette shows the rotation of water molecules, one step in the mechanism, and the grand jeté leap is a metaphor for proton hopping along the water wire, the other step. The backdrop shows two strands of the polymer in the crystal, whose unit cell outline provides a 3D frame for the scene.
