To this day, many people are still convinced by cash, and many arguments and counterarguments can be listed for its use. One of the most convincing arguments is that it is very dirty, which was recently proven with the help of a microscope.
Recently, the cash was examined under a microscope, and the creators of the video revealed a shocking fact: the payment instrument was colonized by bacteria and other pathogens. Samples were taken from metal and paper five hundred, and then cultured on different media. One was nutrient, that is, food nutrients, and the other was on blood agar plates, on which various fungi and bacteria can appear.
In the case of the banknote samples, one or two bacteria grew on nutrient agar, but almost the entire agar plate was covered. On blood agar, the number of bacterial colonies was much higher, and fungal colonies also appeared.
In the case of the metal currency, two dominant bacterial colonies formed on the nutrient, while one colony formed on the blood agar. However, in the latter case, according to the creators of the video, it could be a problem of superinfection, because there was no growth where the sample was drawn on the agar plate, only on the sides of the petri dish.
