OUR SCIENCE EXPERIMENT using a teabag

QUESTION ???   What happens when a teabag is lighted?

                                                            What do you think will happen ?

What happened?  
We saw ashes  
we saw smoke  
                                                       we saw the teabag rise and then come down again

We discovered that cold air is heavier than hot air.
We noticed that hot air rises
