Pyramid-shaped covers used to protect rice in Bangladesh Over 100 of these pyramid-like mounds are seen in Brahmanbaria, Bangladesh! Workers in a rice mill create over 100 even piles of rice and sort them into even rows before downpours come.  The mounds of rice are covered with these pyramid-shaped hats.  The covers are made from bamboo and polythene and are meant to keep the rice dry during rainy nights.
