Roundabout (play)

One type of roundabout which differs significantly in terms of how the rotary motion is provided is a Swedish device called the HAGS Pedal Roundabout, which resembles four small exercise bikes attached to a tubular steel ring, which travel on a circular steel rail on the ground.

[1]The names roundabout, merry-go-round, and carousel are also used, in varying dialects, to refer to a distinct fair or amusement park ride.

An inventor, Ronnie Stuiver, devised a pump powered by a turning children's roundabout, which premiered at an agricultural show in KwaZulu-Natal in 1989.

There are about 600 PlayPumps in South Africa, intended to provide clean drinking water to about one million impoverished people.

[3] UNICEF has released a comprehensive report on the current status of the PlayPump project.
