1. An apparatus for use in a method of detecting change of viscosity to occur in a medium, comprising:

  • (i) a receptacle to contain an amount of the medium, said receptacle including a planar base and a bounding wall upstanding from said base(ii) a structure, and means mounting said receptacle on said structure for rotation of said receptacle with respect to said structure about an axis of rotation normal to the plane of said base, said structure and mounting means being such that said planar base lies at an inclination to the horizontal,(iii) drive means on said structure coupled to said receptacle for rotating said receptacle with respect to said structure,(iv) a ball of greater density than said medium positioned in said receptacle and supported by said planar base and said bounding wall for rolling along said base and wall as the receptacle is rotated.
