This is such a marvelous thing!
African waterwheel
Kids run in a circle and push a merry-go-round faster and faster. Those who are seated on the ride, get dizzy from the speed…laughing and giddy from the force of gravity.
These kids are having so much fun, they don’t seem to realize they’re working. Then again, that’s the idea behind the Play-Pump…a merry-go-round with a mission.
