    I’m wondering how hot air balloons were invented. Did someone in the past started a fire in their tent, and the tent flew away?

      The first hot air balloons were those sky lanterns which were used in China as military signals. It took 1500 years for some bored French guys to say “yeah, let’s make that but big enough to carry us”.
