Watch and cringe: Here’s how much ‘invisible’ toilet water sprays into the air after you flush

Scientists have demonstrated how toilet water sprays when we flush — carrying potentially dangerous germs into the air — in a series of experiments. “But once you see these videos, you’re never going to think about a toilet flush the same way again. The toilet itself was the same kind commonly seen in public bathrooms: a lidless unit accompanied by a cylindrical flushing mechanism. The experimental setup did not include any solid waste or toilet paper in the bowl, and there were no stalls or people moving around. The disconcerting results shed fresh light on just how many particles end up in the air and what size they are.
