DIY experiment shows the power of hand washing over sanitizers
This was a wonderful elementary school classroom experiment that their teacher (Jaralee) helped her students perform. It shows how dirty our hands remain unwashed, merely sanitized, and when washing with soap and water.
No surprise here. Only soap and water keeps your hands as clean and germ-free as possible.
Here's some pictures and more details from another article about her experiment.
But the next picture is the one that got this writer's attention:
One interesting thing is that specimen #5 — the “hand sanitizer” slice — turned out to have a lot of bacteria too. So this is a clear example that hand sanitizer can’t replace proper hand-washing with soap. Jaralee shared the results of the project on Facebook to tell parents teach their kids to wash their hands well and this simple project immediately spread to hundreds of other schools and families. The hand sanitizer slice shook us a little! How about you?
And this is from her facebook post:
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.
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 sanitizer is not an alternative to washing hands!! At all!
This is so DISGUSTING!!!
**All the students touched each piece (of the touched pieces)**
**Results took 3-4 weeks because of preservatives**
**It was plain white bread**
** Editing again to clarify: The control piece wasn't fresh when we took this picture. It just wasn't ever touched with naked hands and it was moved immediately from the bread bag to the zip lock baggie (every piece of bread here is from the same loaf and same day)**
**They're freezer ziplock bags meant for raw meat and they're sealed tight**
**We do sanitize our Chromebooks, obviously we did not do that for this experiment 🙄**
**We are an elementary school. Not a fancy CDC lab, so relax a little and WASH YOUR HANDS**
🚨🚨 Again! This is an elementary school classroom experiment, try not to get upset! 🚨🚨
**I am in no way trying to make Google Chromebooks look bad, all laptops have germs, the amount is based on the person/people using them and not the brand (can't believe I need to specify this)**
**It is just plain soap. Not antibacterial or anything fancy**
**You're all entitled to your opinions. But they may be deleted**
