The central event in Loy Krathong is the launching of krathongs. A krathong is a small lotus-shaped vessel made of banana leaves, flowers, candles, and three incense sticks. Don't be confused by this simple description. Many krathongs are elaborate vessels that take many hours to construct. People launch the krathongs into any "large" body of water to carry away their bad luck. Prior to launching they light the candle and incense and make a wish. It is considered good luck if the krathong floats away from you.
