How to Make a Carbon Dioxide Gas Extinguisher?



 Overview 

As we all know without oxygen, the fire can’t live. Our Carbon Dioxide Gas Extinguisher will show your kids how it actually goes. The required material can be found in almost every home.

 Troubleshooting 

Why didn't I put out the fire? 
The amount of baking soda or vinegar is not enough. Double them. Make sure you use the conical flask to put out the fire as soon as you add the baking soda.


 Scientific Description 

The fire needs oxygen to support it. Adding baking soda into the vinegar creates carbon dioxide gas. When the mouth of the Erlenmeyer is moved near to the fire, the produced carbon dioxide goes out which will take the place of the air around the flame. Thus, there is no oxygen around the fire to support the fire and the fire goes out.


 Extensions 


Is there another way to create carbon dioxide? Lemon juice shares some character with vinegar.

 Disposal 


Pour the liquid into the sink.
