Children weave in and out of scores of giant cones as they roll bicycle tyres around a rice processing plant. The wagon that they are riding is used by workers to transport the rice grains, but after work the children use it as their toy to play with. The kids sometimes help their parents to dry the rice and pack. The playful youngsters dart between the large 'topas' which protect the drying rice overnight. More than 30 children turned the rice mill in Brahmanbaria, Bangladesh, into an obstacle course.
