The PlayPump
The PlayPump is an incredibly simple but effective invention that helps people in Africa access clean drinking water. While children are playing on a merry-go-round up to 1,400 liters of clean water can be pumped into a tank that stands seven meters above the ground. The tank’s walls are used to place ad billboards while two sides are reserved for educational messages. The revenue from ad-sales is put into the maintenance of each pump.
