In an effort to save the environment, public restrooms have begun offering electric hand dryers in place of paper towels. But dryers actually harvest bacteria from the bathroom, which is then transmitted onto hands, according to a shocking video and research conducted by an amateur scientist. That means that after washing your hands to cleanse away germs, electric dryers may just be making them filthy all over again. Amateur Scientist Dallin Lewis conducted his own experiment by placing petri dishes underneath hand dryers in various public restrooms. After letting the bacteria marinate in an incubator he compared his collected samples with a control dish that was meant to mimic someone’s hands air-drying without the use of the air blower. While the control test — or air-drying method — showed no bacteria growth, he discovered noticeable white patches on the petri dishes that were held under electric hand dryers, indicating substantial bacteria growth.
