Originally, the boats were made of banana logs or bamboo but modern versions can be made of wood or synthetic materials. A boat’s length was about 8 to 10 meters. Inside the boat, there were sweets, steamed-sticky rice wrapped in banana leaves (Khao Tom Mud) and other offerings while the outside of the boat was decorated with flowers, joss-sticks, candles and lamps. At night the fire boats were launched on the Mekong River and illuminated in a spectacular display.
