Mr Denn!s' Almost World Famous Homemade Orange Soda-Pop
This experiment's a real gas! And you'll see what I mean when you make a bubbly orange soda-pop that's delicious and good for you too.
Your homemade sodapop will be fizzy and taste like lemon or orange sodapop.
Why this happens:All that bubbling is the result of a chemical reaction between a base and an acid. A base is a compound that gives off negatively charged hydrogen ions when dissolved in water, and an acid is a compound that gives off positively charged hydrogen ions when dissolved in water. When you mix the baking soda (a base) with the lemon or orange juice (an acid), they react and produce a fizzy gas called carbon dioxide. (The bubbles in store-bought sodas are also created by carbon dioxide, but they're added under pressure to water.)
