Glo Germ™ gel is a unique "lotion" that shows how important proper hand washing is to prevent the spread of germs. Just rub the "simulated germ" gel onto your hands like lotion and then thoroughly wash your hands. Your hands look clean, but shine a UV black light on them and you can identify the places where hand washing was ineffective and the residual "glowing germs" show up a brilliant blue-white.
This is a great way to teach your children how to wash their hands well and reduce the spread of germs at home and school. Order with our economical UV black light, sold separately. One 8 ounce bottle is sufficient for 75-100 applications.
