The TikTok profile Devon Science, managed by scientist Ruth, published a study that went viral online, showing why people should not use hand dryers in public restrooms.
Ruth placed a Petri dish under a hand dryer to capture the particles dispersed while it was in operation. She then performed the same procedure with another dish, collecting particles from the air.
She let the dishes rest overnight before showing the results. The dish with particles from the restroom showed significant bacterial and fungal growth, while the dish with particles from the air was nearly clean.
“This is why I don’t use hand dryers,” she said while drying her hands with paper towels. Over 4.7 million people have watched the video. Some users suggested shaking their hands in the air to avoid using too much paper.
