Washing your hands is simple and it's one of the best ways to prevent infection and illness. But these Chiles high schoolers found out that if it's not done right, the germs will still linger.
Students were given gel to put on their hands, which highlights germs in orange under a black light. Then the ninth graders washed their hands and returned to the black light.
"I normally thought I wash my hands really well, but apparently not because it was quite disgusting," said Ashley Lucas, a 9th grader at Chiles High.
"I couldn't believe it was like all on the backs and in between my fingers and on the backs of my hand," said Fred Heery, a 9th grader at Chiles High.
Teachers usually cover this lesson later on in the school year, but this time they're teaching it now in wake of the H1N1 virus. "Letters went out as far as the vaccinations for H1N1 and now is really the time to cover this with the spread of the virus right now going on. We wanted all the students at the school to be aware of this now," said Susan Harris, a teacher at Chiles High.
And teachers are confident this dramatic lesson will leave a lasting impression. "I will be opening doors with my back. I'm scared to touch them now. It's kind of, it's a scary thought, because you hear about people getting sick and dying," said Cassidy Canova, a 9th grader at Chiles High.
As students leave class, educators hope they'll start spreading good hand-washing techniques, not germs. "I'm going to be sure to get between my fingers and under my fingernails whenever I wash my hands. And just sneeze into my arm and wash hands more often and don't touch things that are dirty," said Jordan Maurl, a 9th grader at Chiles High.
Health officials say to be sure your washing your hands long enough, sing the ABC's twice and scrub your arms too.
