Waterbuds were created by two families trying to prevent the spread of germs. A Waterbud is an inexpensive small charm that people can place on water bottles. The ring that goes around the neck of the bottle is made of latex free silicone, so it can tolerate washing, heat and cold. The charms are dishwasher safe, and could even be used with mugs, straws and cans. Waterbuds can be purchased online and in select stores in Virginia.
