This film is a horrible nightmare for any kid with even a hint of germaphobia. I had a hard enough time getting through a day of school without thinking about all the gross people around me. I remember when this information did dawn on me and it was not through some inky smudge demonstration. It was a film that showed how far a sneeze and cough could go in slow motion. From that moment on, I was very aware of everything I was touching and I am still a little nutty about it nowadays.
The takeaway from this film, like so many hygiene education films? People are disgusting.
