Pour Air Onto A Candle (Creative Chemistry Experiments)

You will need:

q A candle
q A transparent glass
q Baking soda
q Vinegar
q Glass
q Tablespoon
q Matchstick

You may have poured water over a flame to put it out. But have you ever tried to pour air? Try this experiment to see how air can be poured over a flame.

INSTRUCTIONS

1. Light a candle and place it on a counter.
2. In the glass, take 4-5 tablespoonfuls of vinegar and when you are ready to extinguish the flame, add 1 teaspoonful of baking soda to the vinegar.
3. Gently, pour the gas that is produced onto the flame.
4. Do not pour the vinegar solution.

RESULT

When baking soda and vinegar are mixed, they produce carbon dioxide. Carbon dioxide is heavier than air, thus it sinks to the bottom. When we tip the glass onto the flame, we actually pour the heavy carbon dioxide gas from the glass onto the flame, which gets extinguished.
