Amazing science experiment: “nothing” put the candles out
What this video shows seems a magic trick but is pure science!
Baking soda (sodium bicarbonate) when is mixed up with vinegar (acetic acid) produces a gas called carbon dioxide. This gas fill the space around the candle flame and put it out because there is no oxygen, essential to combustion.
Some fire extinguishers use this kind of gas.
