Have you ever wondered how many germs are lurking on your laptop?
Or what happens when you dont wash your hands?
EducatorsJaralee Metcalfand Dayna Robertson conducted an experiment, found through theC.S.
One slice (the control) was left untouched.
In addition, a piece of bread was rubbed on all of their classroom laptops.
They then left the bread alone for a few days to watch how the slices reacted.
The results of the experiment will remind you that you shouldalwayswash your hands.
Even hand sanitizer, which we might think as a substitute for hand washing, showed evidence of mold.
But the most disgusting outcomesby farwere the bread slices touched by unwashed hands and wiped on the computers.
The unwashed hands had yellowish mold spread across its surface with some green patches starting to show.
The laptop slice was even worse and had turned almost completely green.
And in Metcalfsnow-viral Facebook post, it is reminding people from around the world to do the same.
The teachers and their students each touched four slices of bread in different states of cleanliness.
One piece of bread was untouched and was the control for the experiment.
Especially the piece that had been rubbed on classroom computers.
