This is no ordinary duster (from the dollar store). This is a brain duster! When students have lost their focus or need to really pay attention I bring out the "brain duster" and gently dust the tops of each child's head. (Lice can't live in the synthetic fibers so don't worry.) If a child covers his or her head or pulls away they are not "dusted". There is no grabbing of the duster and only the teacher is allowed to use it. It is amazing how this actually works as a focus tool. Teacher's can dust their brains too!
