Why does soda fizz?
You crack open a can of soda and — pssshhht! — a cloud of mist escapes. Tiny bubbles race to the surface, tickling your nose. What are those bubbles, and why do they appear the instant you open the can?
The secret is a gas called carbon dioxide, or CO₂ for short. At the factory, workers force this gas into the soda under high pressure — like packing a suitcase so tightly the lid barely closes. The gas dissolves into the liquid, hidden, waiting.
