it flew
the bag was not proper


Results:
Not all of the teabags flew because one did not have a proper bag. The materials of other bags easily burn out and so it had no time to fly.
The teabags flew because of the hot air inside the bag is lighter than the outside that pushed the bag to lift up.


Conclusion:

(class result) not all the tea bags flew
