Charles Ofori Antipem is helping thousands of school children in Ghana learn science with a science kit the size of a textbook.
The race is on at Berekuso Junior High School.
Ofori: Who can get the buzzer to sound first?
Charles has sold 5,000 Science Set to 50 schools across Ghana. Being able to put the sets on the desks of the students and then see them perform science activities, see that glow in their eyes when they build their first electrical circuit. That is what keeps us going.
Charles wants every kid in the country to have access to one in the next two years.
