How to Make Carbon Dioxide

    • 1). Use your funnel to pour about 1 inch of vinegar into your 2-liter soda bottle.

    • 2). Clean and dry your funnel.

    • 3). Use your funnel to slowly add 2 tablespoons of baking soda into the soda bottle. The baking soda and vinegar will fizz. The gas being given off is carbon dioxide. Keep adding the baking soda until there is no more fizzing. The carbon dioxide being given off is heavier than air. Thus, with the bottle upright, the gas will force the air out of the bottle, and the carbon dioxide will remain.

    • 4). Light the candle.

    • 5). Carefully pour the carbon dioxide from the soda bottle over the candle. Pour it just as though it was water or some other liquid. Because it is heavier than air, it will pour out of the bottle and over the flame of the candle and extinguish it. Be sure not to pour any of the vinegar or baking soda out of the bottle, just the gas.
