It is known that space behaves like a 3D rubber sheet, when mass is present, and bends. Gravity can be explained by the curvature of this bending.
Water forms a highly flat surface that also behave like a rubber sheet due to surface tension, be it in 2D. Water striders use the elastic property to propel themselves. The crystal-like aligning of the water molecules at the surface does not go too far to the inside, and soon gives way to the random motion. Thus the skin depth of water is only a few molecules thick.
If this similarity could be taken further, what would be the skin depth of space?
