One could speculate, for example, that long ago the Peep population was located in an industrial area (one of the long-standing Peep mysteries is that they seem to be unusually well adapted to urban areas, while Peep populations in the wilderness are more sparse). Acetone is miscible with water and serves as an important organic solvent in its own right, in industry, home, and laboratory. On the other hand, CuSO4.5H2O and CuSO4 do not dissolve at all.
