Students in the Sedalia Community Center Headstart program, among them, from left, Joel Gutierrez, 4, Mariana Mosley, 5, Janiya Davis, 4, and Juan Buzanes, 5, got a chance Thursday to see how well of a job they did in washing their hands. Letty Rodriguez, an outreach event coordinator for HealthCare USA, pumped a bit of lotion, called Glitter Bug Potion, into each child's cupped hands, and told them to work it into their hands and then to go to the bathroom and wash it off. Upon returning to the classroom the kids slid their hands under a slot in the base of a box containing ultraviolet lamps and peered down another slot to view their hands. Traces of lotion remaining on the hands glowed under the lights. Rodriguez said that she was trying to instill in the kids a habit of attentive hand washing.
