What's that golfball?

My favourite blog, Expolounge, uses the medium of film to explain the history of that giant golfball at Parc Jean-Drapeau - otherwise known as the United States Pavilion of Expo 67 or the Montreal Biosphère. The Biosphère is an environmental museum managed by the federal Government of Canada and is focussed on the ecosystem of the Saint-Lawrence River. It’s worth checking out.
