Class 4 had green glitter germs on their hands and we looked at which was best for getting our hands "glitter germ free" - a dry paper towel, cold water with no soap or warm water with soap. Our hands were only be "glitter free" clean with warm water and soap! Be warned germs everywhere, Class 4 know how to beat you! "Wash, wash, wash your hands, Wash them nice and clean!" Wash the fronts, wash the backs, And wash the inbetweens!"
