The following information is from Wikipedia. A sky lantern, also known as Kongming lantern or Chinese lantern, is a small hot air balloon made of paper, with an opening at the bottom where a small fire is suspended. In Asia and elsewhere around the world, sky lanterns have been traditionally made for centuries, to be launched for play or as part of long-established festivities. The name "sky lantern" is a translation of the Chinese name Tian Deng. Sky lanterns have also been referred to as sky candles or fire balloons; the latter term, however, is also used to refer to balloon munitions used during World War II.
History of sky lantern According to the sinologist and historian of science Joseph Needham, the Chinese experimented with small hot air balloons for signaling from as early as the 3rd century BC, during the Warring States period. Traditionally, however, their invention is attributed to the sage and military strategist Zhuge Liang (181–234 CE) whose courtesy name was Kongming. He is said to have used a message written on a sky lantern to summon help on an occasion when he was surrounded by enemy troops. For this reason they are still known in China as Kongming lanterns . (However, some claim that the name actually comes from the lantern's resemblance to the hat Kongming is traditionally shown to be wearing.)
