Teacher's Bread Science Experiment Shows Why Washing Your Hands Is so Important

By

It's flu season, and the Centers for Disease Control are reporting widespread influenza activity in 23 states. But if that's not enough to make you wash your hands regularly, there's also plenty of stomach bugs that will make you feel pretty miserable throughout the festive period.  

To show her students why washing your hands is so important during the winter months, teacher Jaralee Annice Metcalf decided to run a little science experiment. "We did a science project in class this last month as flu season was starting," Metcalf explained in a Facebook post.  

"We took fresh bread and touched it. We did one slice untouched. One with unwashed hands. One with hand sanitizer. One with washed hands with warm water and soap. Then we decided to rub a piece on all our classroom Chromebooks."

The results were pretty disgusting.
