This story is simply amazing. Kudos to Dayna Robertson and Jaralee Metcalf from Discovery Elementary School in Idaho Falls. In one experiment they were able to articulate what many of us in the cleaning industry have been preaching for years. Well Done!!

Two educators in Idaho Falls teamed up to create the most simple, yet shockingly visual lesson for their students on the benefits of proper hand washing. Teacher Dayna Robertson from Discovery Elementary School teamed up with behavioral specialist Jaralee Metcalf to conduct this simple experiment. They had students touch pieces of white bread according to their hand cleanliness, then placed the bread in sealed plastic bags for 30 days.
