Carbon dioxide is a gas that we interact with every day. For instance, CO2 enables plants to perform photosynthesis, you exhale CO2 when you breathe, and CO2 can extinguish fire. You probably knew all those facts, but did you know that you can get really science-y and extremely creative when putting out flames with CO2? It’s as simple as pouring the gas onto fire. Pouring? You better believe it!

    Obviously it's because the baking soda and vinegar hate the smell of candles! Duh!

    fire goes out because it suffocates. fire needs to breath.

    fire needs oxygen but because we created the co2 from vinegar ang baking soda, the fire extinguishes.. 😀

    We did this I'm science. The vinegar and baking soda to through a chemical reaction and create CO2. The CO2 can extinguish the flames because it suffocates the flame and prevents it from getting any oxygen.

    We tried to replicate some of these demonstrations. Steve Spangler and his crew are just awesome inspiring and teaching people with these videos.

    Since co2 is a heavy gas, it stays in the cup and were you poor it, it is like poring water

    The co2! Because when you mix baking soda and vinegar it creates co2!

    well because mixing the 2 substance creates an invisable gas which makes the fire go out…

    the gasses that are produced by the chemical reaction is cutting the oxygen away from the candles.

    Vinegar is an acid while baking soda is a carbonate! Acid + Carbonate = Salt, Water and Carbon Dioxide. The presence of dense Carbon Dioxide extinguishes the candle fires

    Co2 is a fluid so it "flows" like water 😊
