This teacher’s gross classroom experiment shows what happens when you don’t wash your hands, and I think I’m gonna be sick

If you’re someone who has ever skipped washing their hands, then one teacher’s in-class science experiment could shake you to your very core.

Elementary school teacher Courtney Lee Simpson shared one of her simpler, yet more disgusting classroom experiments, which endeavors to teach kids about the importance of washing their hands — but the scarring image may very well have taught a few adults a thing or two, as well.

The experiment involved slices of bread in plastic bags, each of which had been exposed to varying amounts of germs.

Courtney’s Facebook caption reads:

To all my teacher friends this is the grossest yet coolest experiment. I did this while teaching about germs and how they spread. 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. It is so cool and a great way to teach the importance of hand washing 🙂

Judging from the photos, it’s pretty clear what the takeaway is: dirty hands are pretty much akin to mounds of mold. (I’m editorializing, but you get the point.)

NO THANK YOU. Please keep those moldy bread hands away from me forever.

So, if your kids ever whine about having to wash their hands, this might be a useful little experiment to conduct at home. Not only does it have that kid-appealing gross-out factor, but it’s certainly disturbing enough to make a hand-washer out of even the most slovenly among us. (Maybe.)

An earlier version of this post attributed the experiment to the wrong teacher, we regret the error.
