Under ‘Healthy India Mission’, in the first phase,100 rural schools on the outskirts of 20 cities across India were chosen on the basis of health reports of students. In school, children were handed out these special chalk sticks to write with. While writing, the chalk powder usually accumulates on their hands. At lunch break, when they put their hands under running water, the chalk powder on their hand turns into soap and washes their hands clean. In this process, kids take no extra effort. On Children's Day, this innovation was released as an online video.

Millions of children across rural India still don't have the habit of washing hands with soap before eating. Because they believe washing hands with water is enough. Since children do not take up new habits easily, Savlon, a brand associated with health and hygiene, needed to come up with an idea to help inculcate the habit of using soap when washing hands. Under Savlon’s ongoing school outreach initiative - ‘Healthy India Mission’, the task was to come up with a simple, low-cost solution that could be easily implemented in rural schools across the country.
