TO PROVE THAT AIR IS NEEDED FOR BURNING

Let's see if air is needed for burning or not???


Materials:
Candle
Matches
Glass (make sure the glass is bigger than the candle)


Instructions
Light the candle with the help of matches.
Now cover the burning candle with a glass.


Observe: The flame of the burning candle goes of


What is happening???
The flame goes because of the shortage of the air. The flame is there for a little time after putting the glass as there was little air in the glass!!!


CAUTION: BURNING OF CANDLE UNDER ADULT SUPERVISION
