Answer:

Combine vinegar and baking soda to create a chemical reaction. Carbon dioxide (CO2) gas is formed during this chemical reaction. ... Pouring the heavy CO2 gas over the flame pushes away the oxygen from around the candle causing the fire to go out due to lack of oxygen.

Baking soda, (sodium bicarbonate) is used in class C fire extinguishers. When sodium bicarbonate (baking soda) is heated by the fire it becomes sodium carbonate. ... The carbon dioxide starves the fire of oxygen smothering the fire and the water that is released cools the heat source

How do you make a fire extinguisher with baking soda and vinegar?

Add vinegar to the bottle. Using a funnel, quickly drop the baking soda into the bottle. Being careful not to spill the mixture, hold the bottle at an angle so the carbon dioxide can flow out onto the fire. Notice how carbon dioxide is heavier than air and drops right onto the flame to extinguish it!
