My Science Fair

For the last few weeks I have been working on my science experiment. My title is Can Candles Bow Out By Themselves. I found out that they can because when you mix the vinegar and the bicarbonate soda together it forms carbon dioxide gas. When the carbon dioxide gas rises up the candle, it pushes the oxygen away from the flame and so the candle goes out. Candles can not burn without oxygen so they went out without me blowing them out. This was interesting to watch. I enjoyed this experiment a lot.
