Sky lanterns also known as Kongming Lantern. Made of rice paper with a bamboo frame and has a small candle which when lighted it created heats that cause the lantern to rise into the air. In Thailand, people use Sky Lantern for celebrations and other special occassions. I love the simple form of the sky lanterns and its beautiful light effects that rise and float in the sky at night. There is Yi Peng Lantern Festival every year in Thailand.
