To avoid getting sick, two classroom educators show their students the importance of washing hands.

Teacher Dayna Robertson, 38, and behavior specialist Jaralee Metcalf, 23, conducted their special class to educate students in a month-long experiment designed to show how germs from hands can spread.

Metcalf shared the results on Facebook two weeks ago, and her post has been shared 64,000 times and got 17,000 likes.

“We did a science project in class this last month as flu season was starting. 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 wrote.

Students touched the pieces of plain bread with dirty hands, washed hands with soap and water and after using hand sanitizer. Then, they sealed the pieces in plastic bags and let them sit for three to four weeks.

The results: “This is so DISGUSTING!!!” Metcalf wrote on Facebook.

At the end of the experiment, a piece of bread wiped on Chromebook computers became fully black, while the one touched by dirty hands left with two large patches of yellow and green mold beginning to turn black. The slice touched after using hand sanitizer had a big patch of mold growing on the side.

“If the bread had been exposed to air and moisture, the experiment may have gone faster,” Metcalf told Parents. “The bread that was very clearly exposed to different germs grew mold quicker. And ones touched by clean hands plus the soap and water ones were not exposed to the germs that cause the mold growth to quicken.”

According to the behavioral specialist, it is proved that hand sanitizer is not a good choice for washing hands.

“As somebody who is sick and tired of being sick and tired of being sick and tired. Wash your hands! Remind your kids to wash their hands!” she wrote on Facebook. “And hand sanitizer is not an alternative to washing hands!! At all!”

It is a good lesson that students didn’t take lightly, Robertson told Today.

“The students all thought it was gross,” Robertson told the outlet. “They have really turned their hand-washing around [since the experiment]. They realized that sanitizer doesn’t cut it, and they’ve got to do soap and water.”
