Loi Krathong (also written as Loy Krathong is a festival celebrated annually throughout Thailand and certain parts of Loas and Burma . The name could be translated "Floating Crown" or "Floating Decoration", and comes from the tradition of making buoyant decorations which are then floated on a river.

         Loi means 'to float', while krathong refers to a usually lotus-shaped container which floats on the water. Krathong has no other meaning in Thai besides these decorative floats, so Loi Krathong is very hard to translate, requiring a word describing what a Krathong looks like such as Floating Crown, Floating Boat, Floating Decoration. The traditional krathong are made of the layers of the trunk of a banana tree or a spider lilyplant. Modern krathongs are more often made of bread or styrofoam. A bread krathong will disintegrate after a few days and can be eaten by fish. Banana stalk krathong are also biodegradable, but styrofoam krathongs are sometimes banned, as they pollute the rivers and may take years to decompose. A krathong is decorated with elaborately-folded banana leaves, incense sticks, and a candle. A small coin is sometimes included as an offering to the river spirits. On the night of the full moon, Thais launch their krathong on a river, canal or a pond, making a wish as they do so. The festival may originate from an ancient ritual paying respect to the water spirits.
