This experiment involves an open flame and requires adult help. Never use matches without adult permission and supervision.
Did you know that fire extinguishers often contain carbon dioxide (CO2)––the same gas we exhale, that plants use in photosynthesis, and that's even found in soda? When we use a fire extinguisher or blow out a candle, we're replacing the oxygen around the fire with CO2. Fires need oxygen to burn, and when they run out of oxygen, they go out!
In this experiment, we're going to see how we can put our knowledge of chemical reactions to practical use. In the Fizz-Flator experiment, we saw that vinegar and baking soda combine to produce a large amount of CO2 gas. We're going to use this same reaction to create a simple fire extinguisher.
Hmm... it seems nobody's added a conclusion for this experiment yet. You can suggest one here.
