Teacher's clever lesson on germs makes ALL her students wash their hands

This is so clever.

Getting your children to remember to wash their hands can be difficult.

They've got so many other things to worry about like playing on their iPad for the eighth hour of the day and ignoring you when you ask them to clean their room.

Well, one US teacher has found a way to make sure all of her students wash their hands - through a clever experiment to show how quickly germs can spread.

In a post shared on Facebook, Donna Gill Allen detailed her trick to what she calls the "grossest but coolest experiment."

"You use three pieces of bread. You let all the kids see you put a piece of bread in a baggy with a glove on hence "controlled" then you wash your hands and put a piece of bread in a baggy for "clean" last but definitely not least you pass a piece of bread around and let every kid in class touch it then you put it in a baggy and label it "dirty." Watch how the bread changes over time due to germs."

Donna also included a photo of the three bread slices.

The "dirty" bread did indeed change alright.


Donna finished her post by saying that the experiment taught her students how important it is to wash their hands.

The teacher's post has been liked over 70,000 times by mums, dads, other teachers, and people who are simply impressed by her clever visual experiment.

According to the CDC, many diseases and outbreaks spread due to contaminated hands.

It is also estimated that if everyone in the world washed their hands regularly, almost one million deaths per year could be prevented.

The centre recommends introducing gel hand sanitizers to classrooms to fight infection amoung students.
