The Boun Bang Fai or Rocket Festival, which is celebrated throughout May, marks the sixth month of the lunar calendar. During the festival, Rockets are fired to tempt the gods to produce rain needed for rice cultivation and also to send the Naga from the banks of rivers into the rice fields to help attract rain.
Traditionally, rockets are made by stuffing gunpowder into elaborately decorated bamboo. The rockets are carried to a communal launch-pad. The rocket designed to carry prayers to the rain god during Boun Bang Fai, is known as a Hang or Meun-Saen.
On this occasion, there are special celebrations and dances all throughout Laos. To come and join this amazing celebration is truly a memorable experience for tourists during Green season.
