Patent ID: 7353693

Claim:
An evaluation apparatus for scientific phenomena, comprising: a substrate of a planar shape in whose surface a plurality of long grooves having a cross-sectional area of not more than 1 mm 2 are formed; a plurality of liquid reservoirs formed in the substrate, the plurality of liquid reservoirs each of which has a vent and is 5 to 15000 mm 3 in capacity; and a cover plate which is disposed on the surface of the substrate in close contact therewith and enables a plurality of minute channels to be formed in the substrate by covering the long grooves, wherein: one end of each of the plurality of the channels joins in at a single meeting point and the other end of each of the plurality of the channels communicates with one of the plurality of liquid reservoirs; and when the substrate and cover plate are erected while keeping the substrate and cover plate in close contact with each other so that one or more of the plurality of liquid reservoirs are in a higher position over any other liquid reservoir and liquids are put into the liquid reservoirs in said higher position such that the liquids flow down the channels and the state of the liquids flowing down the channels can be visually recognized.
