Air-dry your hands by shaking them or use an electric hand dryer?
American TikTokeur Lucas Dallin wanted to answer this question by conducting the experiment himself.
Wearing protective gloves and equipped with samples collected from Petri dishes, he toured the public toilets of a service station, a cinema and a store, to demonstrate that these devices found almost everywhere, are veritable breeding grounds for bacteria.
The samples were then placed in an incubator for three days to observe the growth of the bacteria.
And the results are edifying.
All of the samples subjected to the forced air of the hand dryers are filled with questionable color stains.
There is a whole menagerie inside: viruses, microbes, fungi... The hand dryer turns out to be the least hygienic method.
On the contrary, natural drying, shaking hands or with a paper towel remains the best solution.
