Loon Tube: A Teacher’s Simple, But Brilliant Way To Demonstrate Soap’s Effectiveness

A teacher name Amanda Lorenzo has gone viral with her demonstration on the importance of soap.  She put ground pepper in a bowl of water and told her students the pepper represented a virus.  Then she had a student dip her finger into it. The pepper didn’t move, although some of it stuck to the girl’s finger.  So she had the girl dip her finger into some soap. Then she had the girl dip her soapy finger BACK into the original pepper water and when she did, the pepper spread out to the opposite sides of the dish and her finger had no more “virus” on it.
