Experiment Shows How Much Germs Your Computer Collects | Men's Health Magazine Australia

This Experiment On Germs Will Have You Cleaning Your Laptop ASAP

From hair elastics to sponges, phones to water bottles – we’re pretty across the products that house a surprising amount of festy germs thanks to a bunch of “YOU WON’T BELIEVE HOW GROSS [INSERT ITEM] REALLY IS” articles.

But guess what y’all, we’ve got another shocker thanks to the results of a classroom experiment that have gone viral.


Yes, tech-savvy students from the US were shown exactly how germy their devices are with a simple test involving slices of bread. 

Teacher Jaralee Annice Metcalf (who was fed up with always being sick) and her class took five slice of bread, one of which wasn’t touched by bare hands, one that was touched by unwashed hands, one that was touched by washed hands, one was touched by washed and disinfected hands, and one was rubbed on laptops they use in class. 

The slices were place in zip lock bags and left for three weeks. 

In the end, the bread that touched the laptop was by far the most mouldy.

Jaralee posted the results of the experiment on Facebook to tell parents to remind their kids to wash their hands properly with soap and water.

“We did a science project in class this last month as flu season was starting.” she explained. “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! And hand sanitiser is not an alternative to washing hands!! At all! This is so DISGUSTING!!!”
