    How fitting for these kids who are growing up in corona virus times! This looks really simple to do but has a very effective and powerful message. Love it.

    As a nurse, I am always trying to teach my kids about germs! This is a perfect way to clearly illustrate it 🙂 Even before the coronavirus, I was preaching “WASH YOUR HANDS” all the time, lol.

    1. Thank you for reading my blog post. It’s an honor this experiment is nurse approved <3

    I’ve been trying to talk with my daughter about all the invisible germs everywhere.

    Ha, WOW I had no idea the water, pepper and soap would do this…. I guess you learn something new everyday, even when you are a parent! Writing this one down to do with my youngest this week, she’s kind of a germophobe already, she will get a kick out of this.

    We played this for my girls. We are always trying to stress the importance of washing your hands, especially before you eat or if you touch your face. Now we are extra cautious due to covid.
