Easy Science Experiments For Kids: Turn off a candle light with “air”

Here follow my instructions for the turn of a candle with air experiment. This is a really cool trick where it seems like you turn off the candlelight with an empty jug. But is that really the case?

Remember to start the experiment with a hypothesis, what do you think will happen?

Instructions for parents: Read this first.

Material included:

  • A candle
  • One tablespoon of vinegar
  • Two tablespoons of baking soda

Additional things you will need:

  • A lighter


  1. Light the candle.
  2. Pour a couple of tablespoons of vinegar and a tablespoon of baking soda into the jug.
  3. Stir around the vinegar and baking soda with a spoon.
  4. When the mix stops to bubble pour some air from the jug on the candle.
  5. What happens?


When mixing vinegar and baking soda, a chemical reaction starts that creates carbon dioxide. Carbon dioxide is heavier than air and will therefore not disappear from the jug.

To keep a fire alive there are three things are required:

  1. heat
  2. oxygen
  3. fuel

When you pour carbon dioxide over the light, it no longer gets any oxygen and will, therefore, be extinguished.
