1. A method for determining properties of an object having a surface that transitions from a substantially fluid state to a substantially solid state, the method comprising:

  • producing motions in the surface of the object during the substantially fluid state without touching the fluid;

    collecting time-varying signals responsive to the surface motions produced during the substantially fluid state; and

    calculating a value for at least one substantially solid state property of the object based on the time-varying signals collected in the substantially fluid state.
