Q3: Why it can fly?
Ans: The Sky Lantern is the predecessor of the modern hot air balloon, light inside the air heated by burning off expansion. But why the hot air will float? We used Archimedes to explain it: When the object and the air with the same volume, and weight (density) than the hours can be launched into the air, and water the buoyancy of this truth is the same. Heating the air within the ball, the ball part of the air inside the thermal expansion due to air flow from the ball, so that the internal air density, smaller than the outside air, so full of hot air the ball will fly.
