Example #3, the “dirty hands” slice, was covered in spectacular mold growths one month later and didn`t need any additional explanation.

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? How do you teach your kids that they need to wash their hands properly? We’d be happy to hear from you in the comment section below!
