Scientific phenomena evaluation device, diffusion velocity measurement experimental device, and manufacturing method of the device

A manufacturing method of a scientific phenomena evaluation device, comprising:

• forming a first reservoir in a surface of an inverted mold;
• forming a plurality of second reservoirs in the surface of the inverted mold around the formed first reservoir;
• forming a plurality of channels in the surface of the inverted mold through which the formed first reservoir radially communicates with the formed plurality of the second reservoirs;
• applying a resin material to the surface of the inverted mold;
• curing the resin material;
• and
• releasing the cured resin material from the inverted mold to form a base plate,
• wherein the formed plurality of the channels have different sectional areas of 1 mm2 or less, and wherein scientific phenomena in the formed plurality of the channels are visually perceivable.
