Sodium bicarbonate (baking soda) mixed with acetic acid (vinegar) creates CO2 gas. This gas is actually heavier than the air around us and can be easily captured in a cup. When pouring this gas over an open flame the oxygen is displaced and the flame goes out. If you get enough CO2...you can put out A LOT of candles! — — — — — #science #sciences #scienceart #sciencefacts #edu #educational #education #stem #steam #experiment #experiments #nickuhas #candles #bakingsoda #makebakeshake #armandhammer #scienceexperiment #CO2
