The portable tester can determine whether alcohol is watered down or mixed in with another substance.

Contaminated alcohol and its consumption resulting in death is a problem around the world and therefore Kenneth Suslick and Zheng Li of Illinois University have decided to create device that could help to identify counterfeit alcohol.

The tester has 36 dyes, that change color depending on components in the liquor, whereby the partial oxidation of the fluid improves the response of the sensor.
In the experiment, the scientists were able to recognize 14 types of liquor and also determin alcohol that was watered down, even by only 1%.
