How to light our lanterns

How to launch our chinese flying paper lanterns?
Sky lanterns are not that different from hot air balloons, it is the heated air that makes this chinese lantern fly.

Launching or sky lanterns is not difficult, all it takes is enough hot air inside the balloon. It is obvious that heating the air as shown on the left will not work out, these lanterns are grounded forever! However, the guy on the right either knows his natural sciences or simply did read the attached manual: this is how you do it! One person holds the lantern from the top while the other lights the fuel from below.

Hint: the more of the four angles you will light the sooner the lantern will fly, normally it takes about 90 seconds.

Making our lanterns fly is not that difficult at all!
