How to Make a CO2 Fire extinguisher

How to make a CO2 Fire Extinguisher

What you will need: 

1 ice cream container
1 tea light
1 small candle
1 large candle
Vinegar
Baking Soda

What to do:

1.  Place the 2 candles and the tea light in the ice cream container using blue tak.
2.  Pour enough vinegar to make a 1cm deep pool in the ice cream container.
3.  Light the candles.
4.  Sprinkle 1 tsp worth of baking soda into the vinegar and stir.

What should happen:

When the vinegar and baking soda has been stirred the candles should go out after about 5 secs-20 secs.
This is because the baking soda and vinegar are creating CO2 getting rid of the oxygen (fire needs oxygen to burn) and smothering the flame.
