Since this is the land of beer lovers, the Ear cannot resist passing on an AtlasObscura.com story about a Czech brewery’s devotion to the purity of its product (http://tinyurl.com/crayH2O).
To ensure that they are using the cleanest water possible, the brewery has hired five new employees in an unusual experiment. Actually, they are crustaceans. Crawfish, to be exact.
The little critters have been outfitted with infrared sensors on their backs that monitor their heart rates and movement. Some of the water flowing into the brewery vats is diverted into a tank containing the crawdads, and if the heart rates of three or more climb, and they start moving around too much, a computer lets the brewers know there’s a problem with the water within three minutes.
What’s next? Crawdad heart monitors. Na zdravi!
