Preparing a bamboo rocket for the flying contest during Pa'O people National Day in Demoso, Kayah State, Myanmar

The Pwe Lu-Phaing (Fire Rocket Festival), is celebrated from April to July. The purpose of the festival is to bring ample rain to the villages during the planting season. According to Pa'O tradition, rockets are fired to help the clouds make rain. The village headman determines the size of the rockets. The largest rockets can contain up to 20 kilograms of gunpowder and have a range of 5–6 miles. The rockets, originally made from bamboo, are currently made from iron. Prior to firing, the rocket is carried once around the local temple on someone's shoulder. The festival also demonstrates the unity and friendship among different villages as they gather together for one week. "Pwe" means festival, "Lue" means donation and "Phaing" means to remove sins.
