Kate's Corner: Candle extinguisher

By  | 

BRIDGEPORT, W. Va. (WDTV) - In this Kate's Corner, we are going to extinguish a candle with a simple chemical reaction only.

Here's what you'll need:
- A candle
- A lighter or match (adult supervision too)
- A bowl
- Baking soda

With an adult's help, light your candle and place it in the center of your bowl.

Next, sprinkle some baking soda around the candle in the bowl. Then, just add some vinegar and watch what happens to your flame.

The candle goes out. Why is that?

Well, when the baking soda and the vinegar meet they create a chemical reaction. A product of that reaction is carbon dioxide. As the bubbles release the carbon dioxide, it engulfs the flame and cuts off all oxygen. Since oxygen is needed for a fire to burn, the candle extinguishes.
