Do you see the connection between a merry-go-round and a water pump?
In rural and peri-urban communities where access to clear water is precious, the invention of PlayPump is such a life-changing innovation that provides easy access to clean drinking water and bring joy to children. How it works? It is a water pump connected to the merry-go-round installed near schools and powered by children at play.
I was amused when I read it from the magazine. Just a simple idea, and it changes the world.
