Researchers in Chicago recruited children and their parents to use a glowing hand gel to aide in hand hygiene while visiting an ED waiting room.  Half the group used the hand gel alone while the other half were also given proper hand washing instructions.  The gel is used, along with a black light, to determine the areas missed when hand washing.  Even the children who used the Glo Germ Gel alone, without further instruction, were able to improved their hand washing techniques.  Read more about the lasting effects of the study.
