Gas forming cellulitis (video)

Has your stomach ever ached so bad you felt as if it was blown up like a balloon—maybe after the big Thanksgiving meal? You may have had a large amount of gas trapped in your stomach and intestines. But where does the gas come from that makes you feel so uncomfortable? And how does it disappear again? In this activity you will blow some bubbles to investigate how a specific compound can help battle those pockets of air.
Everything you eat ends up in your gastrointestinal, or digestive, tract. This includes your stomach, intestines and other organs that break down the food you eat so that it is useful to your body. Some bubbles of gas (which come from many helpful microorganisms that live inside your gastrointestinal tract to help your body digest food) occur naturally in everyone's body. As gas bubbles form, they can get trapped within the food being digested.
