A Teacher's Brilliant Way to Demonstrate Soap's Effectiveness - Video

A video has been making the rounds of a teacher showing her students the importance of soap. She used ground pepper to represent a virus, and then put the pepper in a bowl of water. She had a student dip a finger into the “virus water.”

The pepper flakes didn’t move, but they DID stick to the girl’s finger, so she had the girl dip her finger in soapy water to clean it off. Then the girl put her soapy finger into the “virus water” . . . and this time the pepper spread out to the opposite sides of the dish, and her finger had no “virus” on it.
