Here, the video and the final image of an experiment are presented:

Description of the experiment: Two round bottom flasks on the left side contain wine, white wine with 12% ethanol (solution S1) and white wine with 12% ethanol and 4% methanol (solution S2). Two experimental Cleardrink™ devices are ready to test the samples for adulteration with methanol. In the left device, plain white wine (S1) is inserted into the R vial and the device is capped. In the right device, adulterated white wine (S2) is inserted into the R vial and the device is capped.

Reactions of the samples with the materials of each R vial begin immediately after the insertion of the samples. In the right device, the initial structure of the R vial's material begins to breakdown, due to the violent conversion of methanol to carbon dioxide gas.

Eventually, results of the each Cleardrink device are visible while observing the D vials. The device on the left side provided a negative to adulteration result, since the initial pink color of the D vial was preserved. In contrast, the device on the right side provided a positive to adulteration result, since the initially pink solution of the D vial has permanently lost its color and is colorless.
