Sky lanterns are small, lightweight balloons made of paper with a flame source at the bottom. When the flame heats the air inside, the lantern becomes buoyant and rises into the sky. Traditionally used in various cultures, they symbolize hope and good fortune. These lanterns are often released during festivals, celebrations, or special events. In some places, they are associated with Buddhism and are used to honor ancestors. However, safety concerns have arisen due to potential fire hazards and environmental impacts, leading to regulations in certain areas regarding their use.
