Cuban children have always built chivichanas for racing, using any wood to hand and ball bearings for wheels. During the hardship of the early 1990s, rural communities realised the potential of the toy and adapted it for personal and cargo transport, but in the streets of Havana it’s all about speed. Health and safety be damned, as up to five kids pile on and clatter downhill and around sharp corners at breakneck speed, steering the front wheel with an ingenious tiller. The film is a thunderous sound piece, too, with exhilarating moments of full immersion.
