The invention of the hot air balloon in ancient China is attributed to the Mongolian military general and inventor, Zhang Heng, during the Han Dynasty around the 2nd century AD. However, the early form of the hot air balloon was known as the "kongming lantern" or "sky lantern," which was used for signaling and celebration. These lanterns utilized heated air to rise, demonstrating the principles of buoyancy that would later be applied in modern hot air balloon design.
