Hand Hygiene and Germ Prevention

Gabby, a graduate student, explains the importance of understanding germs, focusing on viruses and their replication process. She demonstrates how germs spread using a glow lotion and emphasizes the importance of hand hygiene. A second demonstration shows how soap effectively removes germs, highlighting the dual nature of soap molecules. The video aims to educate viewers on preventing the spread of viruses, especially during the coronavirus pandemic.
