It's fun! Make the kids pump the water for the whole village and tell them it's a game. Really, this is serious.
"Play Pumps" are playground merry-go-rounds that pump underground water into large tanks, bringing clean water and a better life to African villages, and laughter to the children. Really, this is serious.
If you don't believe me, visit Play Pumps (dot org), learn how they work, and donate the money to build one. They've built nearly 700 of the things so far, and they won't stop until every African kid has the chance to save his village through playground antics. Really, this is serious.
