Loi Krathong is an annual festival celebrated in Thailand, Laos and Burma. The name translates to "floating flower" and refers to the tradition of making flower parcels to float down rivers and canals. All very pretty and delicate, but the part of this festival that blew me away was the literal blowing away of thousands of lanterns.

Yi Peng is a northern Thai festival that coincides with Loi Krathong. So while there is a week of celebratory activities, including beauty contests, fireworks, and elaborate flower displays, there are also a whole lot of lanterns (khom loi) being let off into the sky.
