A 9-year-old boy in Kenya has won a national award for his invention: a wooden hand-washing machine to help stop the spread of Covid-19 in communities.
Stephen Wamukota told the BBC he only has two machines but wants to make more.
He said he was "very happy" to receive a presidential award for his invention.
Stephen's machine uses a foot pedal to tip a bucket of water onto a user's hands, avoiding touching any surfaces and reducing infections.
