For my teacher/school nurse friends: the importance of handwashing-- Glitter Germs! Put it on the teacher's hands, and then have everyone, including the teacher, shake hands with everyone. Notice how the "germs" spread!
A lovely graphic from the Word Health Organization. They say that "Washing your hands properly takes about as long as singing "Happy Birthday" twice".If it were me, I would use my towel from step 10 to open the bathroom door.
