DIY Fire Extinguisher

We all know how important fire extinguishers are in putting out fires. But how do they work? Fires are created when fuel (wood, gasoline, exc), heat and oxygen are combined. If you remove one of these elements you can stop a fire. Fire extinguishers work by removing oxygen which can make fires spread. One critical chemical in removing oxygen is carbon dioxide. Carbon dioxide is a chemical that is heavier than oxygen. When CO2 is put on a fire it sinks below the oxygen and separates it from the fire, which means no more fire! In this experiment, you and your kids can create CO2 at home by combining baking soda and vinegar. *Parents, children should only be observing this experiment and supervised at all times*

Materials
- 1 Tbsp baking soda
- 1/4 cup vinegar
- 1 tealight candle

Light a small candle. Pour the baking soda and vinegar into a cup and allow the fizz to settle (approximately 5 seconds).

Slowly tilt the cup above the flame. The CO2 gas created from the vinegar and baking soda will fill the cup and extinguish the flame. Do not pour any of the liquid onto the flame. Check out the video below to see this experiment. Have fun!
