Here’s an experiment that uses
Soda Can Fizzy Candy:
Fizzing Soda Candy
Does Soda Can Fizzy Candy really fizz like soda pop?
Materials Needed:
What to do:
- Pour some water into the bowl.
- Put in some Soda Can Fizzy Candy. What happens?
What’s happening:
Soda Can Fizzy Candy fizzes, but not like soda pop. This kind of candy doesn’t contain carbon dioxide bubbles. On the label you’ll see what really makes the bubbles: citric acid and sodium bicarbonate (baking soda). When these ingredients get wet and mix together, the reaction creates carbon dioxide bubbles, just like when you mix vinegar and baking soda.
Pop Rocks are actually closer to soda, because they contain carbon dioxide bubbles trapped in the candy. In fact, Pop Rocks were originally invented by a chemist who trapped carbon dioxide in candy tablets because he was trying to create a way for customers to stir up instant sodas. Although the soda idea didn't work, it became a popular candy.
