On the day of the festival, the Boun Bang Fai becomes a toughly contested completion, which generally only bamboo rockets are allowed to enter. First, each rocket is inspected and categorized. Scores are given for the highest flyer, the most beautiful decoration, and the most entertaining team; a category in which just about anything goes, from elaborate masks to men wearing women’s clothes, while women dance and sing. If any of the rockets fail to explode, the team’s technician and leader are forced to drink muddy water or Satho (rice whisky).
