To entertain children between the ages of 2 and 90, I enjoy popping corks from bottles containing vinegar and baking soda pour about 50 mL of vinegar into a 500-mL plastic bottle. Then I wrap about 5 g of baking soda which is sodium bicarbonate NaHCO3) in one layer of tissue and drop the tissue into the bottle. I place a cork tightly in the mouth of the bottle and step back. The chemical reaction generates CO2(g) that pressurizes the bottle and eventually bursts the cork into the air. Everyone smiles I
