Because of water shortage in Africa, many people have to drink polluted water, which will easily lead to the outbreak of cholera.
We designed a portable water-purification kettle for purifying sewage with a shape of traditional African drum. When African people beat the drum and dance cheerfully with water-purification kettle, the acticarbon package and sewage will react with each other sufficiently and the sewage will be purified, so that African people can drink clean water at any time.
