My child came home from school saying they learned to cough and sneeze into their elbows with Germie Wormie, and I was totally taken aback. I always used my hands. But I went to the website, and now I get it, hands touch, elbows don't!! Kids can touch up to 300 surfaces in 1/2 an hour, and they hate to wash their hands. This is a simple thing that can make a huge difference. There is also an entertaining DVD that teaches kids how to do this and reinforces other important hygiene habits
