STEM Club is working on promoting the washing of hands in developing countries. The Unilever Bright Future project is coming on and they have many good ideas. For example, a ball of soap with water inside for places where the water might be dirty, soap strings that are fun for children to use and a gold solid bar of hand sanitizer.

Other ideas include having a bottle that holds both a sanitizer and liquid soap in a reusable bottle. The whole club makes sodium alginate bubbles to try out the water inside the soap idea. Our plan is to send a Google form to Soweto and ask them which of the ideas might work best in Africa.
