Was It Just Air?

Was it air that made the candle go out? The candle I'm talking about is the candle in our experiment.

   The experiment we did was to test and figure out why the candle went out while there was ethyl alcohol

 in the swoosh bottle. 

   So we had to put the ethyl alcohol in the swoosh bottle. Then Mr.L lit the candle and put it in the bottle with the alcohol in it. When it was in the bottle about close to the top, the candle went out.

   I was told that fire was made with oxygen, fuel, and heat. The candle went out because of the carbon dioxide in the bottle. The carbon dioxide was made by the ethyl alcohol's vapor. The carbon dioxide caused the candle to go out. We all were amazed.
   Our second experiment was related to gases as well.We had vinegar, baking soda, and two graduated cylinders.First Mr.L put baking soda in the first cylinder.Then he pour vinegar inside the cylinder.Afterwards, he lit the candle and lowering in to the cylinder. The candle went out.





Again, the candle went out because of carbon dioxide.
