"The Hunger Games" star Jennifer Lawrence refuses to wash her hands after using public restrooms after a school experiment proved her theory that sinks are a hotbed for killer germs.
The actress admits her eighth grade science project almost shut down her school because she uncovered the filth in the toilets.
She tells Rolling Stone, "I had this theory that hand washing is overrated. And it was true: The bathroom door had the same bacteria as the toilet seat, and the sink was the dirtiest part - it was dirtier than the toilet handle."
