My students are often blown away by the revelation that water is in fact a mineral that happens to be liquid at room temperature. (Just as mercury is a metal with a seriously low melting-point.)

It's a molecule, a substance and the unversal solvent, but a mineral? I've never heard that. Although, under extremely high presure hydrogen can act as a metal, but that doesn't make it one: liquid metalic hydrogen. And I do love Rocky Road ice cream. Water is a mineral?

". . .you want to cool your ice cream so quickly that the crystals don't have time to grow." This is what happens with extrusive igneous bodies. Exposed to the surface, they cool very rapidly, so crystallization is minimal and the rocks are aphanitic (fine-grained). @1: By definition, minerals are solids.

You didn't have to know what you were doing to be able to tell if somebody took their time with the ice cream, because those ice crystals grow quickly. Glad to know I can now add Rock Manufacturing to my résumé.
