Sky lanterns are typically found in East Asian cultures. This lantern is basically a paper balloon that uses a flame as it's source of fuel, it floats as long as it's flame is burning and will slowly returns when the flame dies. The science behind this is simple : as the flame heats the air inside of the lantern, its density is lowered causing the lantern to rise.
A little history...
According to popular folklore, the sky lantern was invented by a Chinese military strategist. They were first used at the turn of the 3rd century as a type of signaling balloon or as some say a sort of spy blimp. Later, they were used in Chinese and Thai festivals. For many Thai's the sky lantern represents their problems and worries floating away.
