It’s that time of year again when the fear of germs comes rushing back along with cold and flu season. The best way to stay safe and ward off those germs is with good old fashioned hand washing. One teacher conducted an experiment to prove why washing properly is so important and everyone needs to see these results.

For every parent who has eyeballed those so-called washed hands and made your kids wash them again, there is finally some vindication thanks to behavior specialist Jaralee Metcalf and teacher Dayna Robertson. The duo shared a class experiment they conducted on germs. “We did a science project in class this last month as flu season was starting,” Metcalf wrote in a Facebook post which has since gone viral.

“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,” she continued.

The results of the experiment are visually stunning and pretty much speak for themselves. Germs are no joke, but proper hand washing can go a long way to protecting you, as the piece of bread touched by washed hands clearly indicates. Even hand sanitizer proved unable to stave off germs the way washing with soap and water does.
