    Learning how to properly wash your hands is a valuable life skill, and one that’s often reinforced in school. Getting kids to understand why, however, can be a challenge. Third grade teacher Marvilyn Lyons and Donna Gill Allen, a health occupation teacher, in Gray’s Creek, North Carolina, showed just how important this is—in a disgustingly memorable way.

    Lyons introduced the lesson to her 3rd graders and Allen shared it in a now-viral Facebook post. “To all my teacher friends this is the grossest yet coolest experiment,” Allen wrote. “I did this while teaching about germs and how they spread.” To start, there were three slices of bread: one that was the control; another clean; and the other dirty. She placed the control piece in a bag while wearing gloves. Afterwards, Lyons washed her hands and put the clean slice in its own bag. Finally, she prepared the dirty slice by having every kid in the class touch the bread; it too went in a sack.

    Over time, the germs on the dirty slice of bread began to grow. Eventually, it lived up to its classification—and then some—by turning green and moldy. (The other slices fared much better.)

    While a memorable science experiment for kids, now hundreds of thousands of adults in the world can picture it every time they need to wash their hands.

    Teachers Marvilyn Lyons and Donna Gill Allen recently introduced a 3rd grade class to a cool science experiment that shows the importance of hand washing.

    After having all the kids in her class touch a single slice of bread, she let the germs spread and it grow moldy over time.

    It’s a disgusting—yet effective—way to remind you to wash your hands!
