3 people minimum are needed. Take one tablespoon of vegetable oil per person and get it all over your hands. Then take 1 teaspoon of cinnamon per person and rub that all over your oily hands. The cinnamon represents germs which you normally can't see.
Now one person washes their hands in cold water only. One person washes their hands in warm water only. The last person washes their hands in warm water and soap.
here are the before....
and after pictures.
The results were that person who washed in cold only stayed pretty germy. person who washed in warm water only got somewhat clean. Person who washed in warm water with soap got almost completely clean.
A good science experiment and hand washing lesson all in one!

Cool! I love it!
Very neat. I've heard of using glitter too but cinnamon would smell so much better! ;-)
I must do this! What a great way to teach the value of washing hands....I sense a fun activity coming on.
Jodi - I'm so glad to have you living a more leisurely pace again and blogging.
