Your favorite soda is packed with a sneaky gas called carbon dioxide (CO₂). That’s the “carbonation” part. During manufacturing, they pump CO₂ into the liquid under high pressure.
That pressure forces the gas to dissolve in the drink. It waits there, trapped, just itching to escape. Your soda can is basically a tiny, tasty prison for gas.

When you open the can, you release the pressure. The gas panics. It rushes to get out, forming all those wonderful bubbles you see.
But those bubbles don’t just stay in the glass. The moment you drink, they ride the liquid straight into your stomach. You’ve just swallowed a gas bomb.
Your stomach is a warm, churning place. The heat helps the CO₂ bubble expand even faster. It’s like a tiny chemistry lab in your gut.
