Students will create a simple homemade fire extinguisher by generating carbon dioxide from vinegar and baking soda. This project tests the effectiveness of CO2 in extinguishing a candle flame.
If carbon dioxide is generated from vinegar and baking soda, then it will extinguish a candle flame.

Pour 100 ml of vinegar into the plastic bottle using a funnel.
Add 2 tablespoons of baking soda into a balloon using a funnel.
Carefully attach the balloon to the bottle's mouth without spilling the baking soda.
Lift the balloon to drop the baking soda into the vinegar.
Observe the reaction and the balloon inflating with CO2.
Light the candle and place it on a stable surface.
Carefully tip the bottle to direct CO2 over the candle flame.
Observe whether the flame extinguishes and record the results.
The carbon dioxide generated from the reaction will displace oxygen around the candle, extinguishing the flame.

Conduct the experiment in a well-ventilated area. Keep flammable materials away from the flame.
Demonstrate the experiment live if possible.
Include a video of the flame extinguishing.
Explain the role of CO2 in fire suppression.
CO2 displaces oxygen, which is needed for combustion.
No, this method is only suitable for small flames, like candles.
The reaction between vinegar and baking soda produces carbon dioxide gas, inflating the balloon.
