Teacher's Awesome Way to Demonstrate Soap's Effectiveness

A teacher name Amanda Lorenzo has gone viral with her demonstration on the effectiveness 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, but some of it did stick to the girl's finger. So she had the girl dip her finger in soap. Then she had the girl dip her soapy finger back into the virus 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 The kids sound astonished and I don't blame them, I thought it was cool too!
