fire balloon

A fire balloon, also known as a fire or sky lantern, is a lightweight paper or fabric envelope attached to a small heat source, typically a candle or fuel cell. When lit, the heat causes the air inside to expand and become less dense, creating buoyancy that lifts the balloon into the sky. These devices are often used for celebrations, festivals, or rituals, and they can carry a message or simply serve as visual displays. Fire balloons are generally safe if handled properly, but they pose fire and environmental risks if not managed responsibly.
