What blows up with vinegar?

Answer 1

Baking soda. Mixed with vinegar it creates a large volume of gas. The only way it "blows up" is if you contain the expanding gasses in a container or bottle. Then the pressure builds up to a point that suddenly bursts the container apart. That's the sort-of explosion that involves no fire, no gunpowder.

Answer 2

GERD sufferers can find a likely ally in the fight for comfort from vinegar. By adding vinegar based dressings to salads or vegetables, acids that rise from the stomach can become neutralized. A teaspoonful of apple cider vinegar at the onset of chest discomfort caused by GERD also provides a quick remedy. Vinegar works by allowing the stomach to regulate natural digestive enzymes, thus preventing acids from rising into the esophagus. This also helps when inadequate amounts of acid are present, which can also cause uncomfortable chest discomfort.
