The fireballs coming out from the water’s surface can be seen once a year on the last night of the Lao Buddhist Lent. The Naga Rockets can be spotted where the Nam Ngum and the Mekong river meet in Thaprabath District, Bolikhamxay Province, as well as in Pak Ngum District, 60 kilometers east of Vientiane
