Sky lanterns are traditionally made out of oiled rice paper stretched over a bamboo frame, containing a small candle. When you light the candle, the air heats up, and the lantern rises into the air. Sky lanterns will stay aloft for around fifteen minutes. These fascinating lanterns are popular in China and Thailand, and are used for special occasions and festivals. Sky lanterns are considered a symbol of good luck.
Sky lanterns, also known as Kongming Lantern are airborne paper lanterns traditionally found in some Asian cultures. They are constructed from oiled rice paper on a bamboo frame, and contain a small candle or fuel cell composed of a waxy flammable material. When lit, the flame heats the air inside the lantern, thus lowering its density causing the lantern to rise into the air.
The sky lantern is only airborne for as long as the flame stays alight, after which
the lantern floats back to the ground.
