As a result of water shortage in Africa, many people often drink polluted water, which easily leads to the outbreak of cholera.
We have designed a portable water purification kettle with a shape of traditional African drum that is able to purify sewage.
When African people beat the drum and dance cheerfully with water purification kettle on their backs, the charcoal package and sewage would be sufficiently reacted with each other and sewage would be purified, thus allowing them to drink pure water in time.
