The popular video’s initial caption said, “No one was hurt. Never attempt this at home. A stunning 10.8 million views were racked up by the video.
A different TikToker, @phonesoap, attempted a comparable experiment with Petri dishes. He also collected air samples from a control dryer that “simulated” shaking his hands dry, in addition to the air samples from the various dryers.
@phonesoap left all of the Petri plates in an incubator for three days in the air dryer video. The hand dryers from the same public restroom as the “control” dish, a gas station, a theater, and a shop all displayed bacterial growth.
