How does the fizz get into soda?

Browse → Stuff We Eat → Sweets & Treats

In order to be so bubbly and fizzy, sodas contain something special called “carbon dioxide,” which is a gas.

The carbon dioxide is put into the soda by a machine at the factory where the soda is being made. The carbon dioxide actually has to be forced into the bottle and then sealed in quickly, because otherwise the carbon dioxide will escape! – The reason the carbon dioxide tries to escape is because it will only stay mixed in with the soda when the bottle or can is sealed under pressure; once the container of soda is opened, the carbon dioxide rises to the top of the soda in the form of bubbles to try and get out!
