We meet Bob Selinger from Chatswood Sunrise Rotary  in Sydney whose club has paid for 156 Hippo Rollers to be made in Cape Town and sent to Pomfret a disadvantaged township in the north of South Africa. Hippo  Rollers are a 90 litre rigid plastic drum pulled with a handle along the ground, saving countless hours of time and replacing the traditional methods of fetching water in buckets and containers carried on the head. Usually by women and children. www.hipporoller.org A simple idea, changinglives.
