At this point in your life, chances are good you’ve mastered basic potty training skills. But there’s one golden rule we don’t all follow in the bathroom: Closing the lid before we flush the toilet.

Maybe you’re a little bit lazy, or maybe you don’t think flushing with the lid down is a big whoop. But have you ever thought about what really happens when you pull that lever with the lid wide open?

The article goes on to state the following:

“You get a good spray out of the toilet area,” explains Charles P. Gerba, a professor of microbiology at the University of Arizona. “When droplets come out of the toilet, it looks like the Fourth of July.”

It’s something called “the aerosol effect”: Instead of colorful sparklers erupting in the sky above you, you’re showered with fecal bacteria and viruses.

According to the report, many germs stay in the toilet bowl after you flush and “simply glom onto the porcelain interior of the bowl.”

When you flush the rush of water into the bowl creates “an aerosol” Jason “The Germ Guy” Tetro, author of “The Germ Files: The Surprising Way Microbes Can Improve Health and Life (and How to Protect Yourself From the Bad Ones)” explains.

“When this happens, any microbes deposited into said toilet may be sent into the surrounding environment.”
