Bar Soap as Emergency Deodorant

I remember 'umpteen' years ago my fifth grade assistant teacher told us girls, "If you're ever out of deodorant and need an emergency fix, wet a bar of soap and rub it under your arms." I have used this tip several times over the years and it really does work to help curb the odor - when in a pinch!:) This is also a good way to avoid using the aluminums found in antiperspirants.
